The franking privilege, which allows Members of Congress to transmit mail matter under their signature without postage, has its roots in 17 th century Great Britain. The British House of Commons in stituted it in 1660 and free mail was available to many officials under the colonial postal system. In 1775, the First Continental Congress passed legislation giving Members mailing privileges so they could communicate with their constituents, as well as giving free mailing privileges to soldiers. Congress continues to use the franking privilege to satisfy an articulated public interest in facilitating official communications from elected officials to the citizens whom they represent. The communications may include letters in response to constituent requests for information, newsletters regarding legislation and Member votes, press releases about official Member activities, copies of the Congressional Record and government reports, and notices about upcoming town meetings organized by Members. Congress pays the U.S. Postal Service for franked mail through annual appropriations for the legislative branch. Each chamber uses a formula to allocate funds to Members from these appropriations. In the Senate, the allocation process is administered by the Committee on Rules and Administration; in the House, by the Committee on House Administration. In the Senate, each Senator's franked mail postage allowance is determined by a formula that gives a maximum allowance equal to the cost of one first-class mailing to every address in the Senator's state. If the total Senate appropriation for official mail is less than the amount required for the maximum allowance, each Senator's allowance is proportionally reduced. A Senate office that exceeds its allowance may supplement the allowance with official office account funds. Senators are, however, limited to $50,000 for mass mailings (defined as 500 or more identical pieces of unsolicited mail) in any fiscal year. In the House, the franked mail postage allowance is based on the number of addresses in each Member's district. Each Representative's mail allowance is combined with allowances for office staff and official office expenses to form a Member's Representational Allowance (MRA). Members may spend any portion of their MRA on franked mail, subject to law and House regulations. Within the limits of their MRA, House Members are not restricted as to the total amount they may spend on mass mailings. The franking privilege is regulated by federal law, House and Senate rules, orders of the Committee on House Administration and Senate Rules and Administration Committee, and regulations of the Senate Select Committee on Ethics and the House Commission on Congressional Mailing Standards. The franking privilege may only be used for matters of public concern or public service. It may not be used to solicit votes or contributions, to send mail regarding political campaigns or political parties, or to mail autobiographical or holiday greeting materials. Both House and Senate regulations specify limitations on the size and formatting of franked mail. Official funds must be used in the preparation of materials sent under the frank; no private funds may supplement printing, production, or other costs. Mass mailings are further restricted by law and chamber rules and regulations. Each mass mailing sent by a Member of Congress must bear the following notice: "Prepared, Published, and Mailed at Taxpayer Expense." Senators are prohibited from sending mass mailings fewer than 60 days prior to any primary election in which they are a candidate, as well as 60 days prior to any general election, regardless of whether or not they are a candidate. House Members are prohibited from sending mass mailings fewer than 90 days prior to any general or primary election in which they are a candidate, and are prohibited from sending unsolicited mass mailings outside their district. Franking regulations also require disclosure of individual Members' mass mailings costs. In the House, costs are reported quarterly in the Statement of Disbursements of the House as part of a total mass communications cost. Senate costs appear in the biannual Report of the Secretary of the Senate . During FY2015, Congress spent $8.3 million on official mail according to the U.S. Postal Service, representing slightly less than two-tenths of 1% of the $4.3 billion budget for the entire legislative branch for FY2015. House official mail costs ($6.8 million) were 82% of the total, whereas Senate official mail costs ($1.5 million) were 18% of the total. During FY2014, Congress spent $16.9 million on official mail. House official mail costs ($15.1 million) were 89% of the total, whereas Senate official mail costs ($1.8 million) were 11% of the total. During FY2013, Congress spent $7.6 million on official mail. House official mail costs ($6.2 million) were 82% of the total, whereas Senate official mail costs ($1.4 million) were 18% of the total. During FY2012, Congress spent $24.8 million on official mail. House official mail costs ($23.3 million) were 94% of the total, whereas Senate official mail costs ($1.5 million) were 6% of the total. These expenditures continue a historical pattern of Congress spending less on official mail costs during non-election years than during election years. However, analysis of monthly data on official mail costs indicates that, due to the structure of the fiscal year calendar, comparisons of election-year and non-election-year mailing data tend to overstate the effect of pre-election increases in mail costs, because it also captures the effect of a large spike in mail costs from December of the previous calendar year. Reform efforts during the past 30 years have reduced overall franking expenditures in both election and non-election years. Even-numbered-year franking expenditures have been reduced by over 85% from $113.4 million in FY1988 to $16.9 million in FY2014, while odd-numbered-year franking expenditures have been reduced by over 90% from $89.5 million in FY1989 to $8.3 million in FY2015. House mail costs have decreased from a high of $77.9 million in FY1988 to $6.8 million in FY2015. The Senate has dramatically reduced its costs, from $43.6 million in FY1984 to $1.5 million in FY2015. H.R. 1873 , the Ending Special Mail Privileges for Congress Act, would eliminate the traditional franking privilege of Members of Congress--the use of the Member's signature in lieu of prepayment for the mailing of letters related to official business. The bill, however, would continue to authorize the use of official funds for the purpose of Member official communications with constituents and others, as "congressional mail." It would also eliminate, without replacement, the franking privilege of survivors of Members of Congress. H.R. 1873 was introduced on April 16, 2015, by Representative Woodall and was referred to the House Committee on House Administration and the House Committee on Oversight and Government Reform. No further action has been taken. One piece of legislation was introduced in the 113th Congress that would have altered the franking privilege. H.R. 4872 , the Ending Special Mail Privileges for Congress Act of 2014, was substantively identical to H.R. 1873 from the 114th Congress. H.R. 4872 was introduced on June 17, 2014, by Representative Woodall and was referred to the House Committee on House Administration and the House Committee on Oversight and Government Reform. No further action was taken. S. 3528 would have repealed the authorization providing franking privileges to former Speakers of the House. Currently, former Speakers are authorized to use the frank for a period of five years after they leave Congress. Senator Jon Tester introduced S. 3528 on September 11, 2012. The bill was referred to the Committee on Rules and Administration. No further action was taken. Two bills introduced in the 111 th Congress-- H.R. 2056 and H.R. 5151 --would have altered the congressional franking privilege. Provisions of the two bills are discussed here. H.R. 2056 (the Clean Money, Clean Elections Act of 2009) would have amended election-year mass-mailing restrictions by altering the period of time during which Members are prohibited from franking any mass mailing and the statutory conditions under which the prohibition applies. If enacted, Members of both the House and Senate would have been prohibited from mailing any mass mailing during the period starting 90 days prior to a primary election in which such Member is a candidate for reelection to any federal office and ending on the day of the general election. Current law and chamber rules provide that a mass mailing may not be franked by a Senator fewer than 60 days, or by a House Member fewer than 90 days, immediately before the date of any primary or general election (whether regular, special, or runoff) in which such Member is a candidate for any public office. Senate rules further state that no Senator may frank mass mailings in the 60 days prior to the general election, regardless of whether or not he or she is a candidate for election. H.R. 2056 would also have prohibited a congressional committee or subcommittee from mailing any mass mailing during the same period individual Members are prohibited from franking any mass mailing, if either the chair or ranking member of the committee or subcommittee is a candidate for reelection to any federal office. Current law does not prohibit congressional committees and subcommittees from sending mass mailings during the election-year period in which individual Members are restricted from franking any mass mailing. Representative John Tierney introduced H.R. 2056 on April 22, 2009. The bill was referred to the Committees on House Administration, Energy and Commerce, Ways and Means, and Oversight and Government Reform. No further action was taken. Previously, similar legislation has been introduced in the 110 th Congress ( H.R. 1614 , S. 936 , and S. 1285 ). Had the legislation been enacted, it would have amended the election-year mass-mailing restrictions on Members by extending the period during which mass mailings were prohibited. H.R. 1614 , introduced by Representative Tierney, was referred to the Committees on House Administration, Energy and Commerce, Ways and Means, and Oversight and Government Reform. No further action was taken. S. 936 , introduced by Senator Richard Durbin, was referred to the Committee on Finance. No further action was taken. S. 1285 , also introduced by Senator Durbin, was referred to the Committee on Rules and Administration. The committee held a hearing on S. 1285 on June 20, 2007. No further action was taken. H.R. 5151 (the Congressional Oversight and Spending Transparency Act of 2010) would have amended existing statutes to prohibit the use of funds of the House of Representatives for official mail of a Member of the House for any material other than a document transmitted under the official letterhead used for Members' stationery. Current law allows Members to send mailings in various forms (newsletters, questionnaires, press releases, notices) without accompaniment of official letterhead. H.R. 5151 would have also required the quarterly reports by the Chief Administrative Officer that disclose expenditures for official mail of the House to include a breakdown of the costs incurred for each category of mass mailing and mass communication. Under current chamber rules and regulations, only the total cost of all mass communications is required to be disclosed. Representative Jeff Flake introduced H.R. 5151 on April 27, 2010. The bill was referred to the Committee on House Administration. No further action was taken. In addition to H.R. 1614 , S. 936 , and S. 1285 described above, two other bills-- H.R. 2687 and H.R. 2788 --were introduced in the 110 th Congress that would have altered the congressional franking privilege. H.R. 2687 would have effectively prohibited Representatives from mass mailing newsletters, questionnaires, or congratulatory notices. The prohibition would not have covered certain other types of mass mailings made by Members, including federal documents (such as the Congressional Record ) or voter registration information. The legislation would have applied only to Representatives; it would not affect mass mailings made by Senators. Current law allows Members to send mass mailings in various forms (newsletters, questionnaires, press releases, notices) on a variety of topics, including but not limited to the impact of laws and decisions, public and official actions taken by Members of Congress, proposed or pending legislation or governmental actions, the positions of the Members of Congress on legislation or other public issues, and other related matters of public concern or public service. H.R. 2687 was introduced June 12, 2007, by Representative Ray LaHood, and was referred to the Committee on House Administration and the Committee on Oversight and Government Reform. No further action was taken. Previously, Representative LaHood introduced similar legislation ( H.R. 3121 , 109 th Congress), which was referred to the Committee on House Administration and the Committee on Government Reform. No further action was taken. H.R. 2788 would have required that each individual piece of franked mail contained in a mass mailing made by a Member of the House contain a statement indicating the aggregate cost of producing and mailing the mass mailing. Each piece of franked mail would have contained the statement, "The aggregate cost of this mailing to the taxpayer is _____," with the blank space containing the total cost of producing and franking the mass mailing. The legislation would not have affected mass mailings made by Senators. Current law requires each mass mailing sent by a Member of Congress to bear the following notice: "Prepared, Published, and Mailed at Taxpayer Expense." H.R. 2788 does not amend the current law; if enacted, mass mailings made by Members of the House would contain both statements. H.R. 2788 was introduced on June 20, 2007, by Representative Jeff Flake, and was referred to the Committee on House Administration. No further action was taken.

Summary:
The congressional franking privilege, which dates from 1775, allows Members of Congress to transmit mail matter under their signature without postage. Congress, through legislative branch appropriations, reimburses the U.S. Postal Service for the franked mail it handles. Use of the frank is regulated by federal law, House and Senate rules, and committee regulations. Reform efforts during the past 30 years have reduced overall franking expenditures in both election and non-election years. Even-numbered-year franking expenditures have been reduced by over 85% from $113.4 million in FY1988 to $16.9 million in FY2014, while odd-numbered-year franking expenditures have been reduced by over 90% from $89.5 million in FY1989 to $8.3 million in FY2015. House mail costs have decreased from a high of $77.9 million in FY1988 to $6.8 million in FY2015. The Senate has dramatically reduced its costs, from $43.6 million in FY1984 to $1.5 million in FY2015. During the 114 th Congress, one piece of legislation ( H.R. 1873 ) has been introduced that would eliminate the traditional franking privilege of Members of Congress--the use of the Member's signature in lieu of prepayment for the mailing of letters related to official business. The bill, however, would continue to authorize the use of official funds for the purpose of Member official communications with constituents and others, as "congressional mail." It would also eliminate, without replacement, the franking privilege of survivors of Members of Congress. An identical bill ( H.R. 4872 ) was introduced in the 113 th Congress. During the 112 th Congress, one piece of legislation was introduced that would have altered the franking privilege for former Speakers of the House. S. 3528 would have repealed the authorization providing franking privileges to former Speakers of the House. During the 111 th Congress, two pieces of legislation were introduced that would have altered the franking privilege for Members. H.R. 5151 would have restricted Representatives' use of the frank to documents transmitted under the official letterhead used for the Member's stationery. H.R. 2056 would have prohibited Senators and Representatives from sending mass mailings during a period starting 90 days prior to a primary and ending on the day of the general election for any election in which the Member is a candidate for reelection. During the 110 th Congress, five pieces of legislation were introduced to alter the franking privilege for Members. One bill would have required that all pieces of mail sent in a mass mailing include a statement indicating the cost of producing and mailing the mass mailing. Another bill would have prohibited mass mailings in the form of newsletters, questionnaires, or congratulatory notices. Three bills would have prohibited Senators and Representatives from sending mass mailings during a period starting 90 days prior to a primary and ending on the day of the general election for any election in which the Member is a candidate for reelection.
