The National Postal Museum was established in 1990 under an agreement between the Smithsonian and US Postal Service to preserve and display the National Philatelic Collection, formerly part of the National Museum of American History. The Postal Museum moved to the Washington City Post Office Building on Capitol Hill in 1993.
