About Us:

The Museum supports a wide variety of interdisciplinary research projects which address topics of importance such as current and future postal operations, as well as philatelic and postal history. Our efforts are a resource and point of reference for research and wider investigation by historians throughout the United States and the world.

The National Postal Museum is divided into galleries that explore America's postal history from colonial times to the present. Visitors learn how mail has been transported and the wondrous diversity of postage stamps. 

The national collection illustrates and invites research into United States philately and postal operations. It contains prestigious postal issues and specialized collections, archival postal documents and three-dimensional objects that trace the evolution of the postal services.
