English Español

ZIP code 21404 covers Annapolis, Maryland. It has no Census ZIP Code Tabulation Area, which is how the Census Bureau treats ZIP codes that are not residential neighbourhoods — PO box-only ranges, military addresses, and codes assigned to a single large organisation. There are no population or income figures for it because nobody is counted as living there.
