The Smithsonian National Postal Museum preserves and interprets postal and philatelic collections to educate, challenge, and inspire audiences about the breadth of American experiences. Based in Washington, DC, it forms part of the Smithsonian’s network of museums in the Museums, Historical Sites, and Zoos sector. The institution serves a public audience of visitors and researchers interested in postal history and philately, offering exhibitions and interpretive programs that place artifacts in context. In 2025 the museum announced it would host the 22nd Maynard Sundman Lecture, scheduled for November, with in-person and online attendance. The organization employs a small to mid-sized staff, reflecting its operations within the Smithsonian system.
