United States Postal Service

The United States Postal Service is the federal office which provides mail delivery to individuals and businesses within the United States. It is often known as just the Post Office.

By the US Constitution, the Post Office has a monopoly on many mail services, although it argues this is necessary to ensure that all Americans can receive mail.

The United States Postal Service (USPS) has a large number of support staff (custodians, office workers, computer operators, mechanics ) in addition to the operations staff who are directly responsible for collecting, sorting, distributing and delivering the mail.

Mail is delivered by City and Rural Carriers Mail is sorted by Mail Handler and Mail Processing Clerks Mail is distributed by Motor Vehicle or Tractor-trailer Operator (driver) Distribution in this case means transportation between post offices or mail processing centers. There are also Clerks at smaller Post Offices who perform a mixture of duties.

Mail is handled according to a category, such as General letter, media mail, postcard or package. Each category has restrictions on content, weight, dimensions and is charged accordingly.
