## Established by Office of Management and Budget Circular A-16, the Federal Geographic Data Committee (FGDC) promotes the coordinated development, use, sharing, and dissemination of geographic data.

The FGDC is composed of representatives from the Departments of
Agriculture, Commerce, Defense, Energy, Housing and Urban Development,
the Interior, State, and Transportation; the Environmental Protection
Agency; the Federal Emergency Management Agency; the Library of
Congress; the National Aeronautics and Space Administration; the
National Archives and Records Administration; and the Tennessee Valley
Authority. Additional Federal agencies participate on FGDC subcommittees
and working groups. The Department of the Interior chairs the committee.

FGDC subcommittees work on issues related to data categories coordinated
under the circular. Subcommittees establish and implement standards for
data content, quality, and transfer; encourage the exchange of
information and the transfer of data; and organize the collection of
geographic data to reduce duplication of effort. Working groups are
established for issues that transcend data categories.

## 1.0 INTRODUCTION

Addresses provide a means of locating people, structures and other
spatial objects. More specifically, addresses are used to reference and
uniquely identify particular points of interest, to access and deliver
to specific locations, and as a means for positioning geographic data
based on location.

Most organizations maintain address lists or have databases or datasets
that contain addresses. In many organizations, the primary purpose for
creating and maintaining address lists and address information is mail
delivery. Organizations often have detailed specifications about the
structure of their address information without defining the content,
i.e., the elements that constitute an address within their system.
Knowledge of both structure and content is required to successfully
share information in a digital environment.

The purpose of this standard is to facilitate the exchange of address
information. The Address Data Content Standard (the Standard) simplifies
the address data exchange process by providing a method for documenting
the content of address information.

## 1.1 Objective

The objective of the Standard is to provide a method for documenting the
content of address information. As a data usability standard, the
Standard describes a way to express the content, applicability, data
quality and accuracy of a dataset or data element.

The Standard additionally codifies some commonly used discrete units of
address information, referred to as descriptive elements. It provides
standardized terminology and definitions to alleviate inconsistencies in
the use of descriptive elements and to simplify the documentation
process.

## 1.2 Scope

The Standard establishes the requirements for documenting the content of
addresses. It is applicable to addresses of entities having a spatial
component[^1]. The Standard does not apply to addresses of entities
lacking a spatial component and specifically excludes electronic
addresses, such as e-mail addresses.

## 1.3 Applicability

The Standard is to be used only in the exchange of addresses[^2]. The
Standard places no requirement on internal organization of use or
structure of address data. However, the principles of the Standard can
be extended to all addresses, including addresses maintained within an
organization, even if they are not shared.

## Related Standards

The Address Data Content Standard recognizes several existing
international, national, federal and agency standards from which
relevant information has been incorporated.

For dated references, only the edition cited applies. For undated
references, the latest edition of the reference document (including any
amendments) applies.

##### International Standards -- 

##### 

##### ISO 11180:1993 Standard for Postal Addressing provides mailing address structure requirements. 

ISO/TC 211 19111, [Geographic Information -- Spatial Referencing by
Coordinates]{.underline} describes the minimum data required to define
1-, 2-, and 3-dimensional coordinate systems that can be the basis for
geographic address types.

ISO/TC 211 19112 [Geographic Information -- Spatial Referencing by
Geographic Identifiers]{.underline} defines the conceptual schema for
spatial references based on geographic identifiers that can be the basis
for physical and postal address types.

1.  National Standards --

    1.  United States --

ANSI X3.61-1986 [American National Standard for Information Systems --
Representation of Geographic Point Locations for
Information]{.underline} defines the use of longitude and latitude
coordinates for geographic point locations.

1.4.2.2 United Kingdom --

BS 7666: [Part 3 Spatial Datasets for Geographic Referencing:
Specification for Address]{.underline} specifies a model and structure
for an address. BS 7666: Part 3 was used as a reference document.

##### FGDC Standards -- 

##### 

##### FGDC-STD-001-1998 Content Standard for Digital Geospatial Metadata (version 2.0) (CSDGM) defines the metadata, part of which documents addresses for contacts (persons and organizations) associated with a geospatial dataset. The CSDGM identifies the following metadata elements related to addresses: address type[^3], address, city, state or province, postal code, and country. A data producer complying with the requirements of both the CSDGM and the Standard will note one inconsistency; the Standard expands the CSDGM closed domain of address type by recognizing a third address type: geographic. This inconsistency should not effect compliance with the requirements of either standard.

FGDC-STD-003, [Cadastral Data Content Standard]{.underline} (CDCS)
provides a model for storing information about geographic and physical
type addresses for cadastral data collections. The CDCS additionally
points to the CSDGM metadata elements to provide information about
locations of agents (persons, organizations or public agencies)
associated with parcels (see FGDC-STD-001-1998).

FGDC-STD-011-2001, [Standard for a United States National
Grid]{.underline} (SUSNG) defines a United States National Grid (USNG)
for use in spatial addressing applications. The SUSNG describes a system
for creating address types that is technically the same as the Military
Grid Reference System, utilizing the public domain system's use of the
Universal Transverse Mercator (UTM) grid. SUSNG addresses are geographic
addresses that can be successfully documented using the Standard's
address specification. The SUSNG applies to all spatial mapping
applications at scales of 1 to 1,000,000 and larger.

###### Agency Standards (United States) -- 

###### 

###### USPS

###### 

###### The United States Postal Service (USPS) maintains a standard, several manuals, and technical guidelines[^4] for mailing type addresses. 

USPS Publication 28, [Postal Addressing Standards]{.underline} provides
a standardized address format and content. It serves as the primary
reference for identifying USPS-recognized data elements and mail
delivery requirements.

USPS [Domestic Mail Manual]{.underline} provides definitions and
elements of a complete delivery address and other information about
domestic mail delivery.

USPS [International Mail Manual]{.underline} provides definitions and
elements of a complete delivery address and other information about mail
for delivery to foreign countries.

USPS [Address Element Correction Technical Guide]{.underline} describes
procedures for correcting USPS-recognized data elements in mailpieces
that have inaccurate or deficient addresses.

USPS [TIGER (Topologically Integrated Geographic Encoding and
Referencing) ZIP Zone Improvement Plan 1998]{.underline} documentation
provides information on the TIGER/ZIP file created by matching
information from the Census Bureau TIGER File to the USPS ZIP+4 Product
and was used as a translation reference source.

USPS [Addressing Standards for Puerto Rico and Virgin
Islands]{.underline} describes the proper format for mailpieces sent to
Puerto Rico and the U.S. Virgin Islands.

The USPS maintains several documents of USPS-recognized data element
domains. The Standard recognizes the USPS domains as approved domains
for mailing address type descriptive elements.

## 1.5 Standards Development Process

The Standard is a new standard; no prior versions exist. The FGDC
Subcommittee on Cultural and Demographic Data (SCDD) sponsored the
development of the Standard. Appendix E (informative) lists SCDD member
agencies. The Standard was drafted, reviewed and discussed at SCDD
meetings from 1996 through 2003. A Public Review was conducted in 2001.
Since then significant changes have been made to the standard that
requires, in the opinion of the SCDD Committee, a second Public Review.
Support from SCDD members included the contribution of agency
specifications in the early stages of development, circulating the
Standard throughout agencies for additional review and comment at
various stages of development, and ensuring a broad review of the
Standard.

Federal, state, local, and private sector organizations reviewed the
Standard and commented during its development.

Papers and presentations about the Standard and its development given
during the process are listed in Appendix E (informative).

## 2.0 DEFINITIONS AND ABBREVIATIONS

2.1 Definitions -- For the purposes of the Standard, the following
definitions apply.

[Address]{.underline} -- The means of referencing an object for the
purposes of unique identification and location.

> *\[ BS 7666: Part 3\]*

NOTE: The Standard does not apply to electronic mail objects.

[Addressee]{.underline} -- The final recipient to which a piece of mail
is addressed.

EXAMPLES 1. Occupant

> 2\. Mr. John Smith
>
> 3\. ABC Company

[Address Group]{.underline} -- A list, dataset or database containing
addresses.

[Address Specification]{.underline} -- The data content of an address
group. This includes an address purpose, an address type and descriptive
elements. If the address type is postal, the specification includes
address structures.

[Address Structure]{.underline} -- The USPS arrangement for the postal
address type that contains all the address elements necessary for
mailing a letter. The Standard identifies four address structures: A
Business Address Structure, a Residential Address Structure, a Military
Address Structure and a Puerto Rico Address Structure.

[Address Type]{.underline} -- The method of referencing an address. The
Standard identifies three address types: geographic, postal and
physical.

[Alias]{.underline} -- A descriptive element that is a name, differing
from the 'Name' descriptive element, commonly used by the data producer
to refer to the address information.

## [Contact]{.underline} -- The person, firm, or establishment associated with an address.

NOTE: A contact for an address may or may not be the addressee of the
address. Differences between a contact and addressee are (1) an
addressee is commonly associated with only one type of address, a postal
address, while a contact can be associated with all types of addresses,
including a postal address, a geographic address or a physical address;
(2) by definition, an addressee's association with an address is
"limited" to receiving mail at an address while a contact's association
with an address can be much broader (refer to EXAMPLES); and (3) a
contact, in the case of a USPS delivery style postal address, does not
necessarily reside at the address, whereas an addressee is believed to
reside at a USPS delivery style postal address.

EXAMPLES 1. An owner responsible for paying the property tax for a
rented dwelling

> 2\. A renter living in a dwelling

3\. A federal agency maintaining a national monument

4\. A mining company leasing the mineral rights on a government land
parcel

5\. A business renting a post office box

[Coordinate Reference System]{.underline} -- A coordinate reference
system is a coordinate system that is related to the real

world by a datum *\[ISO 19111\]*

::: Definition
[Data Producer]{.underline} -- A person or organization that owns,
controls, or maintains an address group and has decided to share the
data.
:::

[Data User]{.underline} -- The person or organization receiving a data
transfer.

[Descriptive Elements]{.underline} -- Discrete units of address
information stored for an address group to document all the information
about an address, or addressee, or contact, that is stored to meet the
address purpose.

[Location]{.underline} -- A location is an identifiable place in the
real world *\[ISO 19112\]*

EXAMPLES 1. Eiffel Tower

#  REQUIREMENT FOR AN ADDRESS SPECIFICATION

An address specification shall accompany an address group distributed by
a data producer or maintenance agency to a data user. It documents the
data content of an address group, but does not assign an obligation to
the physical structure of the data. The address specification explains
why the address database was created, what type of addresses are in the
database, and what type of information or descriptive elements, are
stored in the database. The diagram used to develop the address
specification is presented in Appendix A (informative).

3.1 **Address Purpose** -- An address purpose identifies the data
producer's rationale for creating an address group. A minimum of one
address purpose shall be recorded for each address group, but more than
one address purpose may be recorded. When address groups are created for
multiple purposes, the primary address purpose shall be used, if only
one address purpose is recorded.

3.2 **Address Type** -- An address type identifies the method of
categorizing an address. The Standard recognizes three address types:
Geographic, Postal and Physical. The following table defines each
address type. A minimum of one address type shall be recorded using the
address type primary name.

  ------------ ------------ -----------------------------------------------
  Address type Address type Address type definition
  primary name alias        
               name(s)      

  Geographic   Positional   Set of precise and complete geographic
                            descriptors that use a coordinate reference
                            system to provide the unique location of an
                            object.

  Postal       Mailing      Set of precise and complete information on the
                            basis of which an item can be forwarded and
                            delivered to an addressee. (ISO 11180)

  Physical     Situs,       Set of precise and complete information that
               Delivery     indicates, by relationship or description, the
                            permanent and unique location of an object.
  ------------ ------------ -----------------------------------------------

Table 1. Address Types

Additionally, if an address belongs to more than one address type, all
applicable address types shall be recorded. An address group may contain
one set of addresses belonging to multiple address types (example 1b),
or multiple sets of addresses with each set belonging to a different
address type (example 2). In each case, when more than one applicable
address type exists it shall be recorded.

EXAMPLES 1. a) An address group contains one set of addresses consisting
of entry point (building

entrance) latitude/longitude coordinates. One address type is recorded:
geographic.

b\) An address group contains one set of addresses consisting of both
entry point

latitude/longitude coordinates and overnight delivery location. Two
address types

are recorded: geographic and physical.

2\. An address group contains two sets of addresses: one set consisting
of only entry point latitude/longitude coordinates and one set of
addresses consisting only of overnight delivery location. Two address
types are recorded: geographic and physical.

There is one exception to the requirement to record all address types:
an address can be both a postal address and a physical address. This
occurs when the postal address is an actual site location (such as a
street address) rather than a pick-up location (such as a post office
box). In this case, the data producer may record the primary address
type, based on the address purpose.

EXAMPLES 1. The address group contains street addresses of Federal
agencies (who often maintain post office boxes) for the purpose of
overnight parcel delivery. The addresses belong to both the physical and
postal address types. The data producer elects to record one address
type: physical.

2.  The address group contains USPS-recognized postal addresses within
    the city of Baltimore, MD for the purpose of delivering bulk-rate
    promotional material for a dry-cleaner. A large number of the
    addresses belong to both the physical and postal address types. The
    data producer elects to record one address type: postal.

3.2.1 **Address Structures** -- The USPS identifies four address
structures. This structure is an USPS arrangement that contains all the
elements necessary for mailing a letter using the postal address type.
There are four address structures: Residential Address Structure,
Business Address Structure, Puerto Rico Address Structure and Military
Address Structure. Each structure has a unique set of address
information for achieving a complete postal address[^5]. A decision tree
showing the appropriate structure is shown in Appendix A (informative).

3.  **Descriptive Elements** -- A descriptive element identifies a
    discrete unit of information stored for an

address group. Descriptive elements document all the information about
an address, an addressee, or a contact that has been stored to meet the
address purpose. Appendix B (normative) lists descriptive elements
recognized by the Standard as commonly stored discrete units of
information for an address group. These descriptive elements are
organized by address type. Appendix C (normative) records the recognized
descriptive elements' name, definition and source documentation.

All descriptive elements deemed relevant by the data producer shall be
recorded in an address specification. The amount of information that
shall be recorded for a descriptive element varies, and depends upon
whether or not the descriptive element is recognized by the Standard and
is listed in Appendix C (normative). The recorded information shall
include:

(Normative)

CONFORMANCE TO THE STANDARD:

THE ADDRESS SPECIFICATION

Conforming to the Address Data Content Standard involves three parts.
The first necessary component is the address group; the data that is to
be exchanged. The second part involves explaining the data in the form
of an address specification. Thirdly, metadata is necessary for
documenting the data. The final product of the data transfer shall
include all three parts: the address group, the address specification
and the metadata. Note that the Standard does not impact the internal
structure of the address group nor does it describe distribution
processes.

**Part 1** is the address group. This is the database of addresses that
are to be exchanged. This structure may be in any form that the data
producer chooses.

**Part 2** outlines the procedures the data producer shall use to create
an address specification. The address specification describes the
address group sent by the data producer. It contains four parts:
purpose, address type, address structures and descriptive elements
(Figure A.1). Parts 1, 2 and 4 of the specification apply to all address
groups, regardless of their address type. Part three is only relevant if
the address type is postal.

1\. [Address Purpose]{.underline} -- the data producer's reason for
creating the address group. *(Section. 3.1)*

2\. [Address Type]{.underline} -- the method of categorizing an address.
These addresses can either be geographic,

postal or physical. *(Section. 3.2)*

3\. [Address Structure]{.underline} -- the USPS sanctioned address lines
in the address group. An address

> structure must be identified if the address type is postal. There are
> four address structures: business, residential, military or Puerto
> Rico. (*Section. 3.2.1)* Use the Postal Address Structure Decision
> Tree (Figure A.2) to choose the appropriate address structure

4\. [Descriptive elements]{.underline} -- the discrete units of
information that are in the address group. The descriptive elements
recognized by the standard are listed in Appendix C. If a data producer
uses a descriptive element not recognized by the standard, the data
producer will give the descriptive element's name, the corresponding
ADCS descriptive element if applicable or a definition and reference.
*(Section 3.3)*

> .

**Part 3** is the Metadata. The metadata that accompanies the address
data shall conform to the FGDC [Content Standard for Digital Geospatial
Metadata, Version 2]{.underline}. This metadata shall provide
information about the quality, condition, source and other important
characteristics of the address group.

Figure F. UML Address Specification Model

[^1]: FGDC-approved standards apply to geospatial data. However, data
    associated with an address is clearly georeferenced and therefore
    is, through the address, considered to be geospatial data.

[^2]: The Standard does not require addresses be shared and does not
    provide guidelines for determining whether addresses can be shared.
    Some organizations are prohibited by statute, from sharing addresses
    or some part of address information due to requirements for
    confidentiality and security.

[^3]: The CSDGM domain for address type is "mailing", "physical",
    "mailing or physical", free text. The ADCS uses the term "postal
    address type" in place of "mailing address type" because "postal" is
    defined in ISO 11180, and hence is the preferred definition.

    ^4^Many USPS standards, manuals and technical guidelines are
    available on the Internet (URL =
    [http://www.usps.gov](http://www.usps.gov/))

[^4]:

[^5]: The USPS considers a complete postal address to be all
    USPS-recognized data elements necessary to allow an exact match with
    the current USPS ZIP+4 file to obtain the finest level of ZIP+4
    code.
