The Social Security numbers (SSN), originally created in 1936 to 
track workers' earnings and eligibility for Social Security	 
benefits is now used for many other purposes by both government  
and private sectors. The growth in electronic record keeping and 
the availability of information over the Internet, combined with 
the rise in identity theft, have heightened public concern about 
how their SSNs are being used. Federal agencies use SSNs to	 
manage records, verify the eligibility of benefit applicants,	 
collect outstanding debts, and do research and program		 
evaluation.  GAO found that federal laws designed to protect SSNs
are not being followed consistently, Moreover, courts at all	 
levels of government and offices at the state and county level	 
maintain records that contain SSNs for the purpose of making	 
these records available to the public. Recognizing that these	 
SSNs may be misused, some government entities have taken steps to
protect the SSNs from public display. At the same time, however, 
some government entities are considering making more public	 
records available on the Intranet. Ease of access to		 
electronically available files could encourage more information  
gathering from public records on a broader scale than possible	 
previously.

SOCIAL SECURITY

NUMBERS SSNs Are Widely Used by Government and Could Be Better Protected

Statement of Barbara D. Bovbjerg, Director Education, Workforce, and Income
Security Issues

GAO- 02- 691T

Page 1 GAO- 02- 691T

Chairman Shaw and Members of the Subcommittee: Thank you for inviting me
here today to discuss government use of Social Security Numbers (SSNs).
Although the SSN was originally created in 1936 as a means to track workers?
earnings and eligibility for Social Security benefits, today the number is
used for myriad non- Social Security purposes in both the private and public
sectors. Consequently, the public is concerned with how their personal SSNs
are being used and protected. Further, the growth in electronic record
keeping and the explosion of the availability of information over the
Internet, combined with the rise in reports of identity theft, have
heightened this concern.

We have previously reported that SSNs play an important role in public and
private sectors? ability to deliver services or conduct business. 1 Today, I
will focus on how federal, state, and local governments use SSNs.
Specifically, I will discuss (1) the extent and nature of government
agencies? use of SSNs as they administer programs to provide benefits and
services and the actions government agencies take to safeguard these SSNs
from improper disclosure and (2) the extent and nature of governments? use
of SSNs when they are contained in public records and the options available
to better safeguard SSNs that are traditionally found in these public
records. 2 My testimony is based on our ongoing work conducted at your
request and that of the Subcommittee on Technology, Terrorism and Government
Information, Senate Committee on the Judiciary. To address these issues, we
mailed surveys to programs in 18 federal agencies and those departments that
typically use SSNs in all 50 states, the District of Columbia, and the 90
most populous counties. 3 We also conducted site visits and in- depth
interviews at six selected federal

Commercial Use of the Social Security Number is Widespread, GAO/ HEHS- 99-
28 (Washington, D. C.: Feb. 16, 1999).

2 We found no commonly accepted definition of public records. For the
purposes of this statement, when we use the term public record, we are
referring to a record or document that is routinely made available to the
public for inspection either by a federal, state, or local government agency
or a court, such as those readily available at a public reading room,
clerk?s office, or on the Internet.

3 We did not survey state Departments of Motor Vehicles or state agencies
that administer state tax programs, because we have reported on these
activities separately. See U. S. General Accounting Office, Child Support
Enforcement: Most States Collect Drivers? SSNs and Use Them to Enforce Child
Support, GAO- 02- 239 (Washington, D. C.: Feb. 15, 2002) and Taxpayer
Confidentiality: Federal, State, and Local Agencies Receiving Taxpayer
Information, GAO- GGD- 99- 164 (Washington, D. C.: Aug. 30, 1999).

programs, three states, and three counties. We met with officials
responsible for programs, agencies, or departments (hereinafter referred to
generically as agencies) and courts that make frequent use of SSNs. We
conducted our work between February 2001 and March 2002 in accordance with
generally accepted government auditing standards.

In summary, in delivering services and benefits to the public, federal,
state, and county government agencies use SSNs to manage records, verify the
eligibility of benefit applicants, collect outstanding debts and conduct
research and program evaluation. Using SSNs for these purposes can save the
government and taxpayers hundreds of millions of dollars each year. As they
make use of SSNs for these purposes, government agencies are taking some
steps to safeguard the numbers. However, agencies are not consistently
following federal laws regarding the collection of personal information,
implementing safeguards to protect SSNs from improper disclosure, or
limiting the display of SSN on documents not intended for the public.
Moreover, courts at all three levels of government and certain offices at
the state and county level maintain records that contain SSNs for the
purpose of making them available to the public. Recognizing that these SSNs
may be misused by others, some government entities have taken steps to
protect the SSNs from public display. For example, some have modified forms
so that they can collect SSNs but keep them in a file separate from the
public portion of the record. Nonetheless, although public records have
traditionally been housed in government offices and court buildings, to
improve customer service some government entities are considering placing
more public records on the Internet. The ease of access the Internet affords
could encourage individuals to engage in information gathering from public
records on a broader scale than possible previously. In conclusion, we will
be reporting in more detail on these issues at the end of this month and
look forward to exploring additional options to better protect SSNs with you
as we complete our work.

The use of SSNs by government and the private sector has grown over time, in
part because of federal requirements. In addition, the growth in
computerized records has further increased reliance on SSNs. This growth in
use and availability of the SSN is important because SSNs are often one of
the ?identifiers? of choice among identity thieves. Although no single
federal law regulates the use and disclosure of SSNs by governments, when
federal government agencies use them, several federal laws limit the
Background

use and disclosure of the number. 4 Also, state laws may impose restrictions
on SSN use and disclosure, and they vary from state to state. Moreover, some
records that contain SSNs are considered part of the public record and, as
such, are routinely made available to the public for review.

Since the creation of the SSN, the number of federal agencies and others
that rely on it has grown beyond the original intended purpose. In 1936, the
Social Security Administration (SSA) created a numbering system designed to
provide a unique identifier, the SSN, to each individual. The agency uses
SSNs to track workers? earnings and eligibility for Social Security
benefits, and as of December 1998, SSA had issued 391 million SSNs. Since
the creation of the SSN, other entities in both the public and private
sectors have begun using SSNs, in part because of federal requirements. The
number of federal agencies and others relying on the SSN as a primary
identifier escalated dramatically, in part, because a number of federal laws
were passed that authorized or required its use for specific activities.
(See appendix I for examples of federal laws that authorize or mandate the
collection and use of SSNs.) In addition, private businesses, such as
financial institutions and health care service providers, also rely on
individuals SSNs. In some cases, they require the SSN to comply with federal
laws but, at other times, they routinely choose to use the SSNs to conduct
business.

In addition, the advent of computerized records further increased reliance
on SSNs. Government entities are beginning to make their records
electronically available over the Internet. Moreover, the Government
Paperwork Elimination Act of 1998 requires that, where practicable, federal
agencies provide by 2003 for the option of the electronic maintenance,
submission, or disclosure of information. State government agencies have
also initiated Web sites to address electronic government initiatives.
Moreover, continuing advances in computer technology and the ready
availability of computerized data have spurred the growth of new business
activities that involve the compilation of vast amounts of personal
information about members of the public, including SSNs, that businesses
sell.

4 In this review, we do not include criminal provisions that might apply to
the improper use of SSNs. SSN Use Has Grown, in

Part Because of Federal Requirements

Page 4 GAO- 02- 691T

The overall growth in the use of SSNs is important to individual SSN holders
because these numbers, along with names and birth certificates, are among
the three personal identifiers most often sought by identity thieves. 5
Identity theft is a crime that can affect all Americans. It occurs when an
individual steals another individual?s personal identifying information and
uses it fraudulently. For example, SSNs and other personal information are
used to fraudulently obtain credit cards, open utility accounts, access
existing financial accounts, commit bank fraud, file false tax returns, and
falsely obtain employment and government benefits. SSNs play an important
role in identity theft because they are used as breeder information to
create additional false identification documents, such as drivers licenses.

Recent statistics collected by federal and consumer reporting agencies
indicate that the incidence of identity theft appears to be growing. 6 The
Federal Trade Commission (FTC), the agency responsible for tracking identity
theft, reports that complaint calls from possible victims of identity theft
grew from about 445 calls per week in November 1999, when it began
collecting this information, to about 3,000 calls per week by December 2001.
However, FTC noted that this increase in calls might also, in part, reflect
enhanced consumer awareness. In addition, SSA?s Office of the Inspector
General, which operates a fraud hotline, reports that allegations of SSN
misuse increased from about 11,000 in fiscal year 1998 to more than 65,200
in fiscal year 2001. However, some of the reported increase may be a result
of a growth in the number of staff SSA assigned to field calls to the Fraud
Hotline during this period. SSA staff increased from 11 to over 50 during
this period, which allowed personnel to answer more calls. Also, officials
from two of the three national consumer reporting agencies report an
increase in the number of 7 year fraud alerts placed on consumer credit
files, which they consider to be reliable indicators of the incidence of
identity theft. 7 Finally, it is difficult to determine how many individuals
are prosecuted for identity theft because law enforcement

Identity Theft: Prevalence and Cost Appear to be Growing, GAO- 02- 363
(Washington, D. C.: Mar. 1, 2002). 7 A fraud alert is a warning that someone
may be using the consumer?s personal information to fraudulently obtain
credit. When a fraud alert is placed on a consumer?s credit card file, it
advises credit grantors to conduct additional identity verification before
granting credit. The third consumer reporting office offers fraud alerts
that can vary from 2 to 7 years at the discretion of the individual.
Identity Thieves Often Use

SSNs

Page 5 GAO- 02- 691T

entities report that identity theft is almost always a component of other
crimes, such as bank fraud or credit card fraud, and may be prosecuted under
the statutes covering those crimes.

Most often, identity thieves use SSNs belonging to real people rather than
making one up; however, on the basis of a review of identify theft reports,
victims usually (75 percent of the time) did not know where or how the
thieves got their personal information. 8 In the 25 percent of the time when
the source was known, the personal information, including SSNs, usually was
obtained illegally. In these cases, identity thieves most often gained
access to this personal information by taking advantage of an existing
relationship with the victim. The next most common means of gaining access
were by stealing information from purses, wallets, or the mail. In addition,
individuals can also obtain SSNs from their workplace and use them
themselves or sell them to others. Finally, SSNs and other identifying
information can be obtained legally through Internet sites maintained by
both the public and private sectors and from records routinely made
available to the public by government entities and courts. Because the
sources of identity theft cannot be more accurately pinpointed, it is not
possible at this time to determine the extent to which the government?s use
of SSNs contributes to this problem as compared to use of SSNs by the
private sector.

No single federal law regulates the overall use or restricts the disclosure
of SSNs by governments; however, a number of laws limit SSN use in specific
circumstances. Generally, the federal government?s overall use and
disclosure of SSNs are restricted under the Freedom of Information Act and
the Privacy Act. The Freedom of Information Act presumes federal government
records are available upon formal request, but exempts certain personal
information, such as SSNs. The purpose of the Privacy Act, broadly speaking,
is to balance the government?s need to maintain information about
individuals with the rights of individuals to be protected against
unwarranted invasions of their privacy by federal agencies. Also, the Social
Security Act Amendments of 1990 provide some limits on disclosure, and these
limits apply to state and local governments as well. In addition, a number
of federal statutes impose certain restrictions on

SSN use and disclosure for specific programs or activities. 9 At the state
and county level, each state may have its own statutes addressing the
public?s access to government records and privacy matters; therefore, states
may vary in terms of the restrictions they impose on SSN use and disclosure.

In addition, a number of laws provide protection for sensitive information,
such as SSNs, when maintained in computer systems and other government
records. Most recently, the Government Information Security Reform
provisions of the Fiscal Year 2001 Defense Authorization Act require that
federal agencies take specific measures to safeguard computer systems that
may contain SSNs. 10 For example, federal agencies must develop an agency-
wide information security management program. These laws do not apply to
state and local governments; however, in some cases state and local
governments have developed their own statutes or put requirements in place
to similarly safeguard sensitive information, including SSNs, kept in their
computer systems.

In addition to the SSNs used by program agencies to provide benefits or
services, some records that contain SSNs are considered part of the public
record and, as such, are routinely made available to the public for review.
This is particularly true at the state and county level. Generally, state
law governs whether and under what circumstances these records are made
available to the public, and they vary from state to state. They may be made
available for a number of reasons. These include the presumption that
citizens need government information to assist in oversight and ensure that
government is accountable to the people. Certain records maintained by
federal, state, and county courts are also routinely made available to the
public. In principle, these records are open to aid in preserving the
integrity of the judicial process and to enhance the public trust and
confidence in the judicial process. At the federal level, access to

9 For example, the Internal Revenue Code, which requires the use of SSNs for
certain purposes, declares tax return information, including SSNs, to be
confidential, limits access to specific organizations, and prescribes both
civil and criminal penalties for unauthorized disclosure. For more
information, see GAO- GGD- 99- 164. Also, the Personal Responsibility and
Work Opportunity Act of 1996 explicitly restricts the use of SSNs to
purposes set out in the Act, such as locating absentee parents to collect
child support payments.

10 These provisions supplement information security requirements established
in the federal Computer Security Act of 1987, the Paperwork Reduction Act of
1995, the ClingerCohen Act of 1996, and Office of Management and Budget
guidance. SSNs Are Found in Some

court documents generally has its grounding in common law and constitutional
principles. In some cases, public access is also required by statute, as is
the case for papers filed in a bankruptcy proceeding. As with federal
courts, requirements regarding access to state and local court records may
have a state common law or constitutional basis or may be based on state
laws.

When federal, state, and county government agencies administer programs that
deliver services and benefits to the public, they rely extensively on the
SSNs of those receiving the benefits and services. SSNs provide a quick and
efficient means of managing records and are used to conduct research and
program evaluation. In addition, they are particularly useful when agencies
share information with others to verify the eligibility of benefit
applicants or to collect outstanding debts. Using SSNs for these purposes
can save the government and taxpayers hundreds of millions of dollars each
year. As they make this wide use of SSNs, government agencies are taking
some steps to safeguard the numbers; however, certain key measures that
could help protect SSNs are not uniformly in place at any level of
government. First, when requesting SSNs, government agencies are not
consistently providing individuals with key information mandated by federal
law, such as whether individuals are required to provide their SSNs. Second,
although agencies that use SSNs to provide benefits and services are taking
steps to safeguard them from improper disclosure, our survey identified
potential weaknesses in the security of information systems at all levels of
government. Similarly, sometimes government agencies display SSNs on
documents not intended for the public, and we found numerous examples of
actions taken to limit the presence of SSNs on documents. However, these
changes are not systematic and many government agencies continue to display
SSNs on a variety of documents.

Most of the agencies we surveyed at all levels of government reported using
SSNs extensively to administer their programs. 11 As shown in table 1, more
agencies reported using SSNs for internal administrative purposes, such as
using SSNs to identify, retrieve, and update their records, than for any
other purpose. SSNs are so widely used for this purpose, in part, because
each number is unique to an individual and does not change,

11 Of the respondents to our survey, 14 state program departments and 13
county program departments reported that they do not obtain, receive, or use
the SSN of program participants, service recipients, or individual members
of the public. We did not verify this information. SSNs Are Widely Used

addresses.

Table includes departments and agencies that administer programs and

It excludes state departments of motor vehicles and tax administration.

Many agencies also use SSNs to share information with other entities to
bolster the integrity of the programs they administer. For example, the
majority of agencies at all three levels of government reported sharing
information containing SSNs for the purpose of verifying an applicant?s
eligibility for services or benefits. Agencies use applicants? SSNs to match
the information they provide with information in other data bases, such as
other federal benefit paying agencies, state unemployment agencies, the
Internal Revenue Service, or employers. As unique identifiers, SSNs help
ensure that the agency is matching information on the correct person. Also,
some agencies at each level of government reported sharing data containing
SSNs to collect debts owed them. Using SSNs for these purposes can save the
government and taxpayers hundreds of millions of dollars, such as when SSA
matched its data on Supplemental Security Income recipients with state and
local correctional facilities to identify prisoners who were no longer
eligible for benefits. 12 Doing so helped identify more than $150 million in
Supplemental Security Income overpayments and prevented improper payments of
more than $170 million over an 8- month period. Finally, SSNs along with
other program

disabled.

data, are sometimes used for statistical programs, research, and evaluation,
in part because they provide government agencies and others with an
effective mechanism for linking data on program participation with data from
other sources. 13

When government agencies that administer programs share records containing
individuals? SSNs with other entities, they are most likely to share them
with other government agencies. 14 After that, the largest percentage of
federal and state program agencies report sharing SSNs with contractors (54
and 39 percent respectively), and a relatively large percentage of county
program agencies report sharing with contractors as well (28 percent).
Agencies across all levels of government use contractors to help them
fulfill their program responsibilities, such as determining eligibility for
services and conducting data processing activities. In addition to sharing
SSNs with contractors, government agencies also share SSNs with private
businesses, such as credit bureaus and insurance companies, as well as debt
collection agencies, researchers, and, to a lesser extent, with private
investigators.

In addition, all government personnel departments we surveyed reported using
their employees? SSNs to fulfill at least some of their responsibilities as
employers. Aside from requiring that employers report on their employees?
wages to SSA, federal law also requires that states maintain employers?
reports of newly hired employees identified by SSN. The national database is
used by state child support agencies to locate parents who are delinquent in
child support payments. In addition, employers responding to our survey said
they use SSNs to help them maintain internal records and provide employee
benefits. To provide these benefits, employers often share data on employees
with other entities, such as health care providers or pension plan
administrators.

13 In some cases, records containing SSNs are sometimes matched across
multiple agency or program databases. The statistical and research
communities refer to the process of matching records containing SSNs for
statistical or research purposes as ?record linkage.? See U. S. General
Accounting Office, Record Linkage and Privacy: Issues in Creating New
Federal Research and Statistical Information, GAO- 01- 126SP (Washington, D.
C.: Apr. 2001).

14 On the federal level, data sharing often involves computerized record
matching. The Computer Matching and Privacy Protection Act of 1988, which
amended the Privacy Act, specifies procedural safeguards affecting agencies?
use of Privacy Act records in performing certain types of computerized
matching programs, including due process rights for individuals whose
records are being matched. These due process rights were further clarified
in the Computer Matching and Privacy Protection Amendments of 1990.

Page 10 GAO- 02- 691T

When a government agency requests an individual?s SSN, the individual needs
certain information to make an informed decision about whether to provide
their SSN to the government agency or not. Accordingly, section 7 of the
Privacy Act requires that any federal, state, or local government agency,
when requesting an SSN from an individual, provide that individual with
three key pieces of information. 15 Government entities must

 tell individuals whether disclosing their SSNs is mandatory or voluntary;

 cite the statutory or other authority under which the request is being
made; and

 state what uses government will make of the individual?s SSN. This
information, which helps the individual make an informed decision, is the
first line of defense against improper use.

Although nearly all government entities we surveyed collect and use SSNs for
a variety of reasons, many of these entities reported they do not provide
individuals the information required under section 7 of the Privacy Act when
requesting their SSNs. Federal agencies were more likely to report that they
provided the required information to individuals when requesting their SSNs
than were states or local government agencies. Even so, federal agencies did
not consistently provide this required information; 32 percent did not
inform individuals of the statutory authority for requesting the SSN and 21
percent of federal agencies reported that they did not inform individuals of
how their SSNs would be used. At the state level, about half of the
respondents reported providing individuals with the required information,
and at the county level, about 40 percent of the respondents reported doing
so.

15 Section 7 of the Privacy Act is not codified with the rest of the act,
but rather is found in the note section to 5 U. S. C. 552a. Many Government
Entities

Collect SSNs without Providing Required Information

Page 11 GAO- 02- 691T

When government agencies collect and use SSNs as an essential component of
their operations, they need to take steps to mitigate the risk of
individuals gaining unauthorized access to SSNs or making improper
disclosure or use of SSNs. Over 90 percent of our survey respondents
reported using both hard copy and electronic records containing SSNs when
conducting their program activities. When using electronic media, many
employ personal computers linked to computer networks to store and process
the information they collect. This extensive use of SSNs, as well as the
various ways in which SSNs are stored and accessed or shared, increase the
risks to individuals? privacy and make it both important and challenging for
agencies to take steps to safeguard these SSNs.

No uniform guidelines specify what actions governments should take to
safeguard personal information that includes SSNs. However, to gain a better
understanding of whether agencies had measures in place to safeguard SSNs,
we selected eight commonly used practices found in information security
programs, and we surveyed the federal, state, and county programs and
agencies on their use of these eight practices. Responses to our survey
indicate that agencies that administer programs at all levels of government
are taking some steps to safeguard SSNs; however, potential weaknesses exist
at all levels. Many survey respondents reported adopting some of the
practices; however, none of the eight practices were uniformly adopted at
any level of government. In general, when compared to state and county
government agencies, a higher percentage of federal agencies reported using
most of the eight practices. However, despite the federal government?s self-
reported more frequent use of these practices relative to the state and
counties, it is important to note that since 1996 we have consistently
identified significant information security weaknesses across the federal
government. We are not aware of a comparable comprehensive assessments of
information security for either state or county government. (For additional
information on the eight practices we selected and how they fit into the
federal framework for an information security program, see appendix II.)

Further, when SSNs are passed from a government agency to another entity,
agencies need to take additional steps to continue protections for sensitive
personal information that includes SSNs, such as imposing Many Agencies
Using SSNs

Place

Page 12 GAO- 02- 691T

restrictions on the entities to help ensure that the SSNs are safeguarded.
16 Responses to our survey indicate that, when sharing such sensitive
information, most agencies reported requiring those receiving personal data
to restrict access to and disclosure of records containing SSNs to
authorized persons and to keep records in secured locations. However, fewer
agencies reported having provisions in place to oversee or enforce
compliance with these requirements.

In the course of delivering their services or benefits, many government
agencies occasionally display SSNs on documents that may be viewed by
others, some of whom may not have a need for this personal information.
These documents include payroll checks, vouchers for tax credits for
childcare, travel orders, and authorization for training outside of the
agency. Also, some personnel departments reported displaying employees? SSNs
on their employee badges (27 percent of federal respondents, 5 percent of
state, and 9 percent of county). Notably, the Department of Defense (DOD),
which has over 2. 9 million military and civilian personnel, displays SSNs
on its military and civilian identification cards. On the state level, the
Department of Criminal Justice in one state, which has about 40,000
employees, displays SSNs on all employee identification cards. According to
department officials, some of their employees have taken actions such as
taping over their SSNs so that prison inmates and others cannot view this
personal information.

SSNs are also displayed on documents that are not employee- related. For
example, some benefit programs display the SSN on the benefit checks and
eligibility cards, and over one- third of federal respondents reported
including the SSN on official letters mailed to participants. Further, some
state institutions of higher education display students? SSNs on
identification cards. Finally, SSNs are sometimes displayed on business
permits that must be posted in public view at an individual?s place of
business.

In addition to these examples of SSN display, we also identified a number of
instances where the Congress or governmental entities have taken or are
considering action to reduce the presence of SSNs on documents that may be
viewed by others. For example, the DOD commissary stopped

16 In some cases, where federal agencies administer programs that provide
federal funds to states and counties, the federal agency has spelled out
program- specific requirements for information security that state and
county government agencies are expected to follow when they use federal
funds to operate these programs. Government Agencies

Display SSNs on Documents Not Intended for the Public

requiring SSNs on checks written by members because of concerns about
improper use of the SSNs and identity theft. 17 Also, a state comptroller?s
office changed its procedures so that it now offers vendors the option of
not displaying SSNs on their business permits. Finally, some states have
passed laws prohibiting the use of SSNs as a student identification number.

These efforts to reduce display suggest a growing awareness that SSNs are
private information, and the risk to the individual of placing an SSN on a
document that others can see may be greater than the benefit to the agency
of using the SSN in this manner. However, despite this growing awareness and
the actions cited above, many government agencies continue to display SSNs
on a variety of documents that can be seen by others.

Regarding public records, many of the state and county agencies responding
to our survey reported maintaining records that contain SSNs; however
federal program agencies maintain public records less frequently. At the
state and county levels, certain offices, such as state licensing agencies
and county recorders? offices, have traditionally been repositories for
public records that may contain SSNs. In addition, courts at all three
levels of government maintain public records that may contain SSNs.
Officials who maintain these records told us their responsibility is to
preserve the integrity of the record rather than protect the privacy of the
individual SSN holder. However, we found examples of some government
entities that are trying innovative approaches to protect the SSNs in such
records from public display. Moreover, the general public has traditionally
gained access to public records by visiting the office that maintains the
records, an inconvenience that represents a practical limitation on the
volume of SSNs any one person can collect. However, the growth of electronic
record- keeping places new pressures on agencies to provide their data to
the pubic on the Internet. Although few entities report currently making
public records containing SSNs available on the Internet, several officials
told us they are considering expanding the volume and type of such records
available on their Web site. This would create new opportunities for
gathering SSNs on a broader scale. Again, some entities

17 As of March 2002, the Navy Commissary still requires SSNs on checks.
Officials told us they hope to implement a system similar to the DOD
Commissary by the end of 2002. Open Nature of

are considering alternatives to making SSNs available on such a wide scale,
while others are not.

As shown in table 2, more than two- thirds of the courts, county recorders,
and state licensing agencies that reported maintaining public records
reported that these records contained SSNs. 18 In addition, some program
agencies also reported maintaining public records that contain SSNs.

agencies. It excludes state departments of motor vehicles and tax
administration.

County clerks or recorders (hereinafter referred to as recorders) and
certain state agencies often maintain records that contain SSNs because
these offices have traditionally been the repository for key information
that, among other things, chronicles various life events and other
activities of individuals as they interact with government. 19 SSNs appear
in these public records for a number of reasons. They may already be a part
of a document that is submitted to a recorder for official preservation. For
example, military veterans are encouraged to file their discharge papers,
which contain SSNs, with their local recorder?s office to establish a
readily available record of their military service. 20 Also, documents that
record financial transactions, such as tax liens and property settlements,
contain

18 Of the respondents to our survey, 20 county recorders and courts and 5
state courts reported that they do not obtain, receive, or use the SSN of
program participants, service recipients, or individual members of the
public. We did not verify this information.

19 It differs from state- to- state as to whether certain records, such as
marriage licenses and birth certificates, are maintained in county or state
offices. Certain documents, however, such as land and title transfers, are
almost always maintained at the local, or county, level.

20 Veterans are advised that these are important documents which can be
registered/ recorded in most states or localities for a nominal fee making
retrieval easy. In October 2001, DOD added a cautionary statement that
recording these documents could subject them to public access in some states
or localities. Many State and County

Public Records Contain SSNs

SSNs to help identify the correct individual. In other cases, government
officials are required by law to collect SSNs. For example, to aid in
locating non- custodial parents who are delinquent in their child support
payments, the federal Personal Responsibility and Work Opportunity
Reconciliation Act of 1996 requires that states have laws in effect to
collect SSNs on applications for marriage, professional, and occupational
licenses. Moreover, some state laws allow government entities to collect
SSNs on voter registries to help avoid duplicate registrations. Although the
law requires public entities to collect the SSN as part of these activities,
this does not necessarily mean that the SSNs always must be placed on the
document that becomes part of the public record.

Courts at all three levels of government also collect and maintain records
that are routinely made available to the public. Court records overall are
presumed to be public; however, each court may have its own rules or
practices governing the release of information. 21 As with recorders, SSNs
appear in court documents for a variety of reasons. In many cases, SSNs are
already a part of documents that are submitted by attorneys or individuals.
These documents could be submitted as part of the evidence for a proceeding
or could be included in documents, such as a petition for an action, a
judgment or a divorce decree. In other cases, courts include SSNs on
documents they and other government officials create, such as criminal
summonses, arrest warrants, and judgments, to increase the likelihood that
the correct individual is affected (i. e. to avoid arresting the wrong John
Smith). In some cases federal law requires that SSNs be placed in certain
records that courts maintain, such as records pertaining to child support
orders, divorce decrees, and paternity determinations. Again, this assists
child support enforcement agencies in efforts to help parents collect money
that is owed to them. These documents may also be maintained at county clerk
or recorders? offices.

When federal, state, or county entities, including courts, maintain public
records, they are generally prohibited from altering the formal documents.
Officials told us that their primary and mandated interest is in preserving
the integrity of the record rather than protecting the privacy of the
individual named in the record. Officials told us they believe they have no

21 In some states, for example, adoption records, grand jury records, and
juvenile court records are not part of the public record. In addition, some
court documents pertinent to the cases may or may not be in the public
record, depending on local court practice. Finally, the judge can choose to
explicitly seal a record to protect the information it contains from public
review.

Page 16 GAO- 02- 691T

choice but to accept the documents with the SSNs and fulfill the
responsibility of their office by making them available to the general
public.

When creating public documents or records, such as marriage licenses, some
government agencies are trying new innovative approaches that protect SSNs
from public display. For example, some have developed alternative types of
forms to keep SSNs and other personal information separate from the portion
of a document that is accessible to the general public. 22 Changing how the
information is captured on the form itself can help solve the dilemma of
many county recorders who, because they are the official record keepers of
the county, are usually not allowed to alter an original document after it
is officially filed in their office. For example, a county recorder told us
that Virginia recently changed its marriage license application so that the
form is now in triplicate, and the copy that is available to the general
public does not contain the SSN. However, an official told us even this
seemingly simple change in the format of a document can be challenging
because, in some cases, the forms used for certain transactions are
prescribed by the state. In addition to these efforts at recorders offices,
some courts have made efforts to protect SSNs in documents that the general
public can access through court clerk offices. For example, one state court
offers the option of filing a separate form containing the SSN that is kept
separate from the part of the record that is available for public
inspection.

These solutions, however, are most effective when the recorder?s office,
state agencies, and courts prepare the documents themselves. In those many
instances where others file the documents, such as individuals, attorneys,
or financial institutions, the receiving agency has less control over what
is contained in the document and, in many cases, must accept it as
submitted. Officials told us that, in these cases, educating the individuals
who submit the documents for the record may help to reduce the appearance of
SSNs. This would include individuals, financial institutions, title
companies, and attorneys, who could begin by considering whether SSNs are
required on the documents they submit. It may be possible to limit the
display of SSNs on some of these documents or, where SSNs are deemed
necessary to help identify the subject of the documents, it may be possible
to truncate the SSN to the last four digits.

22 In some cases, however, the law requires that the SSN appear on the
document itself, as on death certificates. Alternatives to Displaying

SSNs in Public Records Exist

Page 17 GAO- 02- 691T

While the above options are available for public records created after an
office institutes changes, fewer options exist to limit the availability of
SSNs in records that have already been officially filed or created. One
option is redacting or removing SSNs from documents before they are made
available to the general public. In our fieldwork, we found instances where
departments redact SSNs from copies of documents that are made available to
the general public, but these tended to be situations where the volume of
records and number of requests were minimal, such as in a small county. Most
other officials told us redaction was not a practical alternative for public
records their offices maintain. Although redaction would reduce the
likelihood of SSNs being released to the general public, we were told it is
time- consuming, labor intensive, difficult, and in some cases would require
change in law. In documents filed by others outside of the office, SSNs do
not appear in a uniform place and could appear many times throughout a
document. In these cases, it is a particularly lengthy and labor- intensive
process to find and redact SSNs. Moreover, redaction would be less effective
in those offices where members of the general public can inspect and copy
large numbers of documents without supervision from office staff. In these
situations, officials told us that they could change their procedures for
documents that they collect in the future, but it would be extremely
difficult and expensive to redact SSNs on documents that have already been
collected and filed.

Traditionally, the public has been able to gain access to SSNs contained in
public records by visiting the recorder?s office, state office, or court
house; however, the requirement to visit a physical location and request or
search for information on a case- by- case basis offers some measure of
protection against the widespread collection and use of others? SSNs from
public records. 23 Yet, this limited access to information in public records
is not always the case. We found examples where members of the public can
obtain easy access to larger volumes of documents containing SSNs. Some
offices that maintain public records offer computer terminals on site where
individuals can look up electronic files from a site- specific database. In
one of the offices we visited, documents containing SSNs that were otherwise
accessible to the public were also made available in bulk to certain groups.
When asked about sharing information containing SSNs with other entities, a
higher percentage of county recorders reported sharing information
containing SSNs with marketing companies,

23 Some jurisdictions also permit citizens to request public records through
the mail. Traditional Access to

Public Records Has Practical Limitations That Would Not Exist if the Records
Were Placed on the Internet

Page 18 GAO- 02- 691T

collection agencies, credit bureaus, private investigators, and outside
researchers.

Finally, few agencies reported that they place records containing SSNs on
their Internet sites; however, this practice may be growing. Of those
agencies that reported having public records containing SSNs, only 3 percent
of the state respondents and 9 percent of the county respondents reported
that the public can access these documents on their Web site. In some cases,
such as the federal courts, documents containing SSNs are available on the
Internet only to paid subscribers. However, increasing numbers of
departments are moving toward placing more information on the Internet. We
spoke with several officials that described their goals for having records
available electronically within the next few years. Providing this easy
access of records potentially could increase the opportunity to obtain
records that contain SSNs that otherwise would not have been obtained by
visiting the government agency.

While planning to place more information on the Internet, some courts and
government agencies are examining their policies to decide whether SSNs
should be made available on documents on their Web sites. In our fieldwork,
we heard many discussions of this issue, which is particularly problematic
for courts and recorders, who have a responsibility to make large volumes of
documents accessible to the general public. On the one hand, officials told
us placing their records on the Internet would simply facilitate the general
public?s ability to access the information. On the other hand, officials
expressed concern that placing documents on the Internet would remove the
natural deterrent of having to travel to the courthouse or recorder?s office
to obtain personal information on individuals.

Again, we found examples where government entities are searching for ways to
strike a balance. For example, the Judicial Conference of the United States
recently released a statement on electronic case file availability and
Internet use in federal courts. They recommended that documents in civil
cases and bankruptcy cases should be made available electronically, but SSNs
contained in the documents should be truncated to the last four digits.
Also, we spoke to one county recorder?s office that had recently put many of
its documents on their Web site, but had decided not to include categories
of documents that were known to contain SSNs. In addition, some states are
taking action to limit the display of SSNs on the Internet. Given the likely
growth of public information on the Internet, the time is right for some
kind of forethought about the inherent risk

Page 19 GAO- 02- 691T

posed by making SSNs and other personal information available through this
venue.

SSNs are widely used in all levels of government and play a central role in
how government entities conduct their business. As unique identifiers, SSNs
are used to help make record- keeping more efficient and are most useful
when government entities share information about individuals with others
outside their organization. The various benefits from sharing data help
ensure that government agencies fulfill their mission and meet their
obligation to the taxpayer by, for example, making sure that the programs
serve only those eligible for services. However, the gaps in safeguarding
SSNs that we have identified create the potential for SSN misuse. Although
the extent to which the government?s broad use of SSNs contributes to
identity theft is not clear, measures to encourage governments to better
secure and reduce the display of SSNs could at least help minimize the risk
of SSN misuse. It is important to focus on ways to accomplish this. We will
be reporting in more detail on these issues at the end of this month and
look forward to exploring additional options to better protect SSNs with you
as we complete our work.

Certain federal laws lay out a framework for federal agencies to follow when
establishing information security programs to protect sensitive personal
information, such as SSNs. 1 The federal framework is consistent with
strategies used by private and public organizations that we previously
reported have strong information security programs. 2 This framework
includes four principles that are important to an overall information
security program. These are to periodically assess risk, implement policies
and controls to mitigate risks, promote awareness of risks for information
security, and to continually monitor and evaluate information security
practices. To gain a better understanding of whether agencies had in place
measures to safeguard SSNs that are consistent with the federal framework,
we selected eight commonly used practices found in information security
programs- two for each principle. Use of these eight practices could give an
indication that an agency has an information security program that follows
the federal framework. 3 We surveyed the federal, state, and county programs
and agencies on their use of these eight practices:

Periodically assess risk

 Conduct risk assessments for computer systems that contain SSNs

 Develop written security plan for computer systems that contain SSNs 1 See
federal Government Information Security Reform provisions of the fiscal year
2001 Defense Authorization Act, the federal Computer Security Act of 1987,
the Paperwork Reduction Act of 1995, the Clinger- Cohen Act of 1996, and
Office of Management and Budget guidance.

2 U. S. General Accounting Office, Executive Guide: Information Security
Management, Learning From Leading Organizations, GAO/ AIMD- 98- 68
(Washington, D. C.: May 1998) reported on strategies used by private and
public organizations- a financial services corporation, a regional utility,
a state university, a retailer, a state agency, a nonbank financial
institution, a computer vendor, and an equipment manufacturer- that were
recognized as having strong information security programs. The information
security strategies discussed in the report were only a part of the
organizations? broader information management strategies.

3 States may also require any number of the eight practices, but the
requirements would vary from state to state. Appendix II: Our Eight
Practices and How

They Fit Into the Federal Framework for an Information Security Program

 Control access to computerized records that contain SSNs, such as
assigning different levels of access and using methods to identify employees
(e. g., use ID cards, PINS, or passwords)

Promote awareness of risks for information security

 Provide employees training or written materials on responsibilities for
safeguarding records

 Take disciplinary actions against employees for noncompliance with
policies, such as placing employees on probation, terminating employment, or
