United States Postal Service

The United States Postal Service (USPS), also known as the Post Office, U.S. Mail, or Postal Service, is an independent agency of the executive branch of the United States federal government responsible for providing postal service in the U.S., its insular areas, and its associated states. It is one of the few government agencies explicitly authorized by the Constitution of the United States. As of 2023, the USPS has 525,469 career employees and 114,623 non-career employees.[4]: 3

The USPS has a monopoly on traditional letter delivery within the U.S. and operates under a universal service obligation (USO), both of which are defined across a broad set of legal mandates, which obligate it to provide uniform price and quality across the entirety of its service area.[5] The Post Office has exclusive access[6] to letter boxes marked "U.S. Mail" and personal letterboxes in the U.S., but has to compete against private package delivery services, such as United Parcel Service, FedEx, and DHL.[7]

Universal service obligation and monopoly status[edit]

Legal basis and rationale[edit]

Article I, section 8, Clause 7 of the U.S. Constitution grants Congress the power to establish post offices and post roads,[142] which has been interpreted as a de facto Congressional monopoly over the delivery of first-class residential mail—which has been defined as non-urgent residential letters (not packages). Accordingly, no other system for delivering first-class residential mail—public or private—has been tolerated, absent Congress's consent. The mission of the Postal Service is to provide the American public with trusted universal postal service. While not explicitly defined, the Postal Service's universal service obligation (USO) is broadly outlined in statute and includes multiple dimensions: geographic scope, range of products, access to services and facilities, delivery frequency, affordable and uniform pricing, service quality, and security of the mail. While other carriers may claim to voluntarily provide delivery on a broad basis, the Postal Service is the only carrier with a legal obligation to provide all the various aspects of universal service.[143]


Proponents of universal service principles claim that since any obligation must be matched by the financial capability to meet that obligation, the postal monopoly was put in place as a funding mechanism for the USO, and it has been in place for over a hundred years. It consists of two parts: the Private Express Statutes (PES) and the mailbox access rule. The PES refer to the Postal Service's monopoly on the delivery of letters, and the mailbox rule refers to the Postal Service's exclusive access to customer mailboxes.[144]


Proponents of universal service principles further claim that eliminating or reducing the PES or mailbox rule would affect the ability of the Postal Service to provide affordable universal service. If, for example, the PES and the mailbox rule were to be eliminated, and the USO maintained, then either billions of dollars in tax revenues or some other source of funding would have to be found.[144]


Some proponents[145] of universal service principles suggest that private communications that are protected by the veil of government promote the exchange of free ideas and communications. This separates private communications from the ability of a private for-profit or non-profit organization to corrupt. Security for the individual is in this way protected by the United States Post Office, maintaining confidentiality and anonymity, as well as government employees being much less likely to be instructed by superiors to engage in nefarious spying. It is seen by some as a dangerous step to extract the universal service principle from the post office, as the untainted nature of private communications is preserved as assurance of the protection of individual freedom of privacy.[146]


However, as the recent notice of a termination of mail service to residents of the Frank Church–River of No Return Wilderness indicates, mail service has been contracted to private firms such as Arnold Aviation for many decades. KTVB-TV reported:[147]

Financial services[edit]

Postal money orders provide a safe alternative to sending cash through the mail, and are available in any amount up to $1,000. Like a bank check, money orders are cashable only by the recipient. Unlike a personal bank check, they are prepaid and therefore cannot be returned because of insufficient funds.[254] Money orders are a declining business for the USPS, as companies like PayPal, Venmo and others are offering electronic replacements.


From 1911 to 1967, the Postal Service also operated the United States Postal Savings System, not unlike a savings and loan association with the amount of the deposit limited.[255]


A January 2014 report by the inspector general of the USPS suggested that the agency could earn $8.9 billion per year in revenue by providing financial services, especially in areas where there are no local banks but there is a local post office, and to customers who currently do not have bank accounts.[256]

, also referred to as mailmen or mail carriers, prepare and deliver mail and parcels. They are divided into two categories: City Letter Carriers, who are represented by the NALC, and Rural Letter Carriers, who are represented by the NRLCA. City Carriers are paid hourly with automatic overtime paid after 8 hours or 40 hours a week of duty. City Carriers are required to work in any kind of weather, daylight or dark and carry three bundles of mail (letters in one hand with magazines and other larger mail pieces) on the forearm carrying the mail. Advertisement mail, Every door direct (EDD) and smaller parcels all go in the carriers satchel). Larger parcels, up to a total of 70 lbs. may be delivered at various times of the day or with the mail. Mail routes are outfitted with a number of scanpoints (mailbox barcodes) on random streets every 30 to 40 minutes apart to keep track of the carriers whereabouts in real-time.

Letter carriers

Rural carriers are under a form of salary called "evaluated hours", usually with overtime built into their pay. The evaluated hours are created by having all mail counted for a period of two or four weeks, and a formula used to create the set dollar amount they will be paid for each day worked until the next time the route is counted.

Mail handlers and processors, prepare, separate, load and unload mail and parcels, by delivery ZIP code and station, for the clerks. They work almost exclusively at the plants or larger mail facilities now after having their duties assessed and reassigned to clerks in Post Offices and Station branches.

Clerks, have a dual function by design of where their assignment is. Window clerks directly handle customer service needs at the counter, sort box mail and sort first-class letters, standard and bulk-rate mail for the carriers on the work floor. Clerks may also work alongside mail handlers in large sorting facilities, outside of the public view, sorting mail. Data Conversion Operators, who encode address information at Remote Encoding Centers, are also members of the clerk craft. Mail handlers and Clerks are represented by the NPMHU and the APWU, respectively.

In the film (1947), the identity of Kris Kringle (played by Edmund Gwenn) as the one and only "Santa Claus" was validated by a state court, based on the delivery of 21 bags of mail (famously carried into the courtroom) to the character in question. The contention was that it would have been illegal for the United States Post Office to deliver mail that was addressed to "Santa Claus" to the character "Kris Kringle" unless he were, in fact, the one and only Santa Claus. Judge Henry X. Harper (played by Gene Lockhart) ruled that since the U.S. Government had demonstrated through the delivery of the bags of mail that Kris Kringle was Santa Claus, the State of New York did not have the authority to overrule that decision.

Miracle on 34th Street

The novel (1971), written by poet and novelist Charles Bukowski, is a semi-autobiographical account of his life over the years as a letter carrier. Bukowski would, under duress, quit and years later return as a mail clerk. His personal account would detail the work at lengths as frustrating, menial, boring, and degrading.
