The United States Postal Service was inaugurated in 1971, and is currently headed by Megan Brennan, Postmaster General

History of the US Post Office

The U.S. Mail traces its roots to 1775 during the Second Continental Congress, where Benjamin Franklin was appointed the first Postmaster General. The Post Office Department was created in 1792 from Franklin's operation, elevated to a cabinet-level department in 1872, and transformed in 1971 into the U.S. Postal Service as an independent agency under the Postal Reorganization Act.
