 | | The United States Postal Service (USPS) is an "independent establishment of the executive branch" of the United States government (see 39 U.S.C.) responsible for providing postal service in the United States; it is generally referred to within the United States as "the post office." |
 | | The USPS is the third-largest employer in the United States (after the United States Department of Defense and Wal-Mart), and operates the largest civilian vehicle fleet in the world, with an estimated 170,000 vehicles, the majority of which are the easily identified "mail trucks," as shown in the pictures to the right. |
 | | It does, however, receive compensation from taxpayer funds for certain services that it is mandated to provide for free or at a discount, including free mail for the blind, military mail, nonprofit mail and overseas ballots. |
