Fort Smith, AR

ZIP code 72918 is a PO-box-only postal designation for Fort Smith, Arkansas, rather than a mapped residential area, so it has no clearly defined set of landmarks. Fort Smith’s notable sites include Fort Smith National Historic Site, Miss Laura’s Visitor Center, the Fort Smith Museum of History, and the U.S. Marshals Museum, but they should not be assumed to lie within 72918 without a specific street address.
