Parcel Return Service, DC

ZIP code 56972 is a special-use postal code associated with Washington, D.C., rather than a conventional neighborhood with defined geographic boundaries. As a result, landmarks cannot be reliably identified as lying within the ZIP code itself. Major landmarks in Washington, D.C., include the White House, the U.S. Capitol, the Washington Monument, and the National Mall, but they should not be assumed to be within 56972.
