Mobile, AL

ZIP code 36621 is a PO Box ZIP associated with Mobile, Alabama, rather than a conventional residential area with defined neighborhood boundaries. As a result, landmarks cannot be reliably assigned to the ZIP itself. Major landmarks in the broader city include USS Alabama Battleship Memorial Park, the Cathedral Basilica of the Immaculate Conception, Fort Conde, and GulfQuest National Maritime Museum. These are Mobile attractions, not necessarily within 36621.
