The U.S. Postal Service’s Use of Contractors
to Deliver Mail

Analyst in American National Government
Government and Finance Division
Summary
During the 110th Congress, three measures, H.Res. 282, S. 1457, and H.R. 4236,
have been introduced to address the U.S. Postal Service’s (USPS’s) use of private
contractors to deliver mail. This report provides information on the USPS’s authority
to contract and data on the USPS’s use of private contractors to deliver mail. It notes
that the USPS has statutory authority to contract, although the extent of that authority
has been contested. It also shows that the USPS has increased its use of contractors in
recent years, but that the USPS employees continue to serve more than 98% of all U.S.
homes and businesses. This report will be updated as developments warrant.
Recent Concerns and Legislation
Some members of the 110th Congress have expressed concern about the USPS’s
practice of contracting with private individuals and firms, often called “contractors” and
“subcontractors,” for the collection and delivery of mail.1
Contractors have transported mail between postal facilities since at least 1792 (1
Stat. 233), and according to the USPS, contractors have delivered mail to homes since
1900.2 Today, contractors transport mail between postal facilities via land, air, water, and
rail.3 One type of land (i.e., “surface”) mail transportation contract is the “highway

contract route” (HCR).4 HCR contracts come in three subtypes. Under “transportation”
contracts, private “suppliers”5 transport mail between postal facilities. “Combination”
contracts require suppliers to make a small number of mail deliveries in the course of
transporting mail between the USPS’s facilities. “Contract delivery service” (CDS)
contracts compensate suppliers for collecting and delivering mail in rural areas.6 This
latter subtype of contract has been the focus of recent controversy.
In 2007, the leaders of some of the USPS employee unions suggested that the USPS
was expanding its use of CDS carriers. For example, John Hegarty, National President
of the National Postal Mail Handlers Union (NPMHU), claimed that, “From all
indications, there is a contracting-out virus that seems to be infecting Postal Service
Headquarters.”7 William Young, President of the National Association of Letter Carriers
(NALC), which represents city carriers, called upon Congress to “stop the cancer of
contracting out before it spreads.”8 Both the NALC and the National Rural Letter Carriers
Association (NRLCA) alleged that contractors cannot be trusted to deliver the mail.9 The
unions also claimed that CDS carriers were delivering mail in suburban and urban
locales.10
4 HCR contractors are sometimes called “star contractors.” In 1845, Congress first mandated that
the Postmaster General openly bid mail transportation contracts and award them to the lowest
bidders who tendered “sufficient guarantees for faithful performance, without other reference to
the mode of such transportation than may be necessary to provide for the due celerity, certainty,
and security of such transportation” (5 Stat. 738). To save time and effort, postal clerks often
substituted asterisks for the words “celerity, certainty, and security” when they recorded these
postal contracts in ledgers; hence, the terms “star contracts” and “star contractors.” National

USPS, meanwhile, denied that it was greatly expanding the use of CDS carriers and
argued that contract mail delivery was “not new.” According to the USPS, contractors
collect and deliver mail mostly in rural areas. The USPS noted that contractors are less
expensive to employ than career delivery carriers, and that using them makes business
sense.11 The USPS also declared that it is not replacing career carriers with contractors.
Rather, the USPS reported that it considers assigning only new delivery routes to
contractors.12
On March 28, 2007, Representative Albio Sires introduced H.Res. 282, which
expressed “the sense of the House of Representatives that the United States Postal Service
should discontinue the practice of contracting out mail delivery services.” H.Res. 282
was referred to the House Committee on Oversight and Government Reform (HCOGR).
Nearly two months later, the first of two bills that would limit the USPS’s authority to
contract for mail delivery appeared. S. 1457, introduced by Senator Tom Harkin on May
23, 2007, would forbid the USPS from entering “into any contract ... with any motor
carrier or other person for the delivery of mail on any route with 1 or more families per
mile.” The bill would permit all existing CDS contracts to remain in effect and to be
renewed. S. 1457 was referred to the Senate Committee on Homeland Security and
Governmental Affairs. A second bill, H.R. 4236, was introduced by Representative
Stephen F. Lynch on November 15, 2007. The bill would curtail the USPS’s contracting
authority by requiring it to bargain with postal unions before entering into any “contract
providing for mail processing, mail handling, or surface transportation of mail, if such
contract would, for any 12-month period, involve the equivalent of 50 or more workyears
of work that would otherwise be performed by career postal employees.”13 H.R. 4236 was
referred to the HCOGR’s Subcommittee on Federal Workforce, Postal Service, and the
District of Columbia, which held a hearing to examine the issue on July 19, 2007.14
The controversy over the USPS’s contracting of mail delivery raises two basic
questions: (1) by what authority may the USPS contract for mail delivery; and (2) to what
extent is the USPS using CDS carriers to deliver mail? The answers follow in the next
sections.

The USPS’s Authority to Contract
The Postal Reorganization Act of 1970 (PRA; P.L. 91-375; 84 Stat. 725) replaced
the U.S. Post Office Department with the U.S. Postal Service, an independent
establishment of the executive branch (39 U.S.C. 201). PRA requires the USPS to
“maintain an efficient system of collection, sorting, and delivery of the mail nationwide”
(39 U.S.C. 403(b)(1)). PRA provides the USPS with considerable discretion over its
operations. Among its many authorities, the USPS has the power to (1) “enter into and
perform contracts” (39 U.S.C. 401); (2) “provide for the collection, handling,
transportation, delivery, forwarding, returning, and holding of mail” (39 U.S.C.
404(a)(1)); and (3) “establish mail routes and authorize mail transportation service
thereon” (39 U.S.C. 5203(a)).15
Some postal unions have contended that the USPS’s use of CDS instead of career
delivery carriers “violates the spirit of the nation’s basic postal law.”16 PRA states,
It shall be the policy of the Postal Service to maintain compensation and benefits for
all officers and employees on a standard of comparability to the compensation and
benefits paid for comparable levels of work in the private sector of the economy (39
U.S.C. 1003(a)).
Career delivery carriers are civil servants and, under PRA, are entitled to wages
established through contracts collectively bargained by the USPS and postal unions (39
U.S.C. 1001(b) and 39 U.S.C. 1201 et seq.). Using contractors, the unions argue,
circumvents the collective bargaining process and opens the door for the USPS to replace
all career delivery carriers with contractors. The USPS has responded that its contracts
with the postal unions recognize USPS’s authority to use contractors.17
The Extent of the USPS’s Use of CDS Carriers
to Deliver Mail

Between 1998 and 2007, the number of carrier routes18 served by CDS carriers rose
from 5,424 to 6,531, or 20.4% (Table 1). However, throughout this period, the USPS
career city and rural carriers delivered mail on the vast majority of postal carrier routes
(Table 1 and Table 2). Similarly, between 1997 and 2006, the USPS city and rural
delivery carriers served the vast majority of delivery points (Table 3 and Table 4). Thus,
although the USPS has increased its use of CDS carriers to deliver mail, these contractors

Outlook
For the time being, it appears that the USPS and the NALC have settled their dispute
over the use of contractors to deliver mail.
On October 9, 2007, the NALC and the USPS signed a new collective bargaining
agreement. The agreement included memoranda of understanding that instituted a six-
month moratorium “on any new subcontracting of delivery in offices in which city letter
carriers are currently employed.” The agreement also committed the USPS and the
NALC to establishing a “joint committee” to study “the problems” of the contracting out
of mail delivery that will lead “towards a meaningful evolutionary approach to the issue
of subcontracting.”20 The NALC has reported that it and the USPS drew up a list of 3,600
post offices that will be “protected” from contracting. According to the NALC, the USPS
is obliged to terminate any CDS contracts at these offices.21
The moratorium was extended by the two parties until September 30, 2008. The
next month, the USPS and the NALC announced that they had signed two memoranda of
agreement that extend the moratorium until 2011 and set up processes by which the two
parties can reach decisions over the use of contractors in some areas.22
