US Postal Service

The United States Postal Service, also known as the USPS, was a pre-War government agency responsible for transporting packages, letters and other mail across the United States. It is unknown how the Postal Service and the United States Post Office Department functioned together, or if the Postal Service replaced the Post Office Department as in reality.

Background
The USPS ran post offices across the country, and pre-War records of its policies and other information can be found on a terminal in the Clarksburg Post Office in Appalachia.

Appearances
The United States Postal Service is mentioned only in Fallout 76.
