Our BLOG is dedicated to sharing behind-the-scenes stories, thoughts, and interesting discussion about our museum and our renowned collection. We very much look forward to participating in engaging conversations with people from around the world!

The National Postal Museum, part of the Smithsonian Institution, was established in 1990 through an agreement between the Smithsonian Institution and the United States Postal Service. The museum opened to the public on July 30, 1993 in the historic City Post Office building adjacent to Union Station near the U.S. Capitol in Washington, DC.

The museum occupies 100,000 square feet, with 35,000 square feet devoted to exhibition space. The museum also houses a 6,000 square foot research library, a United States Postal Service philatelic retail store, and a museum gift shop.

The National Postal Museum has the largest philatelic and postal history collection of any museum in the world and the second largest collection within the Smithsonian.

The National Philatelic Collection contains more than six million postage and revenue stamps, stamped envelopes and postal stationery, rare and unique philatelic proofs and essays. The Postal History Collection features a wide range of objects related to the history of the post, including mailboxes, mail sorting equipment, patent models, and historic postal vehicles.

The museum features highly interactive rotating and permanent exhibitions and is noted for providing a fun, family-friendly educational experience for visitors of all ages. In addition to its many exhibits, the museum also offers a full range of public programs, lectures, and workshops and hosts numerous special events. The museum also has an award-winning website that offers special online exhibits, access to the collections and resources and information about the museum, stamps and stamp collecting, and the history of the post.
