Parcel Return Service, DC

ZIP code 56935 is a special-purpose postal code associated with Washington, D.C., rather than a conventional neighborhood with a defined residential area. As a result, landmarks cannot be reliably identified as being within the ZIP code itself. The U.S. Capitol, the White House, the National Mall, and the Smithsonian museums are major landmarks in Washington, but their presence in the city does not establish that they are located in 56935.
