The United States Postal Service (USPS) is an independent branch of the federal government responsible for providing Postal Service in the United States. The USPS handles the mailing of letters and packages, sorting and delivering mail, and selling postal products like stamps, mailing supplies and commemoratives.

People mail their letters and packages by placing them in a mailbox or taking them directly to the post office. At the post office, postal workers sort the mail by size. Letters go through a machine that cancels the stamps. Postal workers then sort the mail according to its destination (the place where it is going).

A postal service is a shipping company that’s normally operated by national governments. Postal services can be used for delivery of your parcels and important documents, but many businesses prefer to use them to send non-urgent, routine communications to business partners and customers.

The Post Office Department was created in 1792 with the passage of the Postal Service Act. It was elevated to a cabinet-level department in 1872, and was transformed by the Postal Reorganization Act of 1970 into the United States Postal Service as an independent agency.

In the more than two centuries since Benjamin Franklin was appointed our first Postmaster General in 1775, the Postal Service™ has grown and changed with America, boldly embracing new technologies to better serve a growing population.
