How Wisconsin Counties and 5-Digit FIPS Codes Work
In U.S. Census Bureau TIGER/Line geography, Wisconsin (WI) is assigned the 2-digit state Federal Information Processing Series (FIPS) code 55 and covers 54,168 square miles of land area across 72 counties in the Central Time (CT) zone (with Madison as the state capital). Every county in the directory above carries a unique 5-digit GEOID formed by combining state prefix 55 with a 3-digit county code (ranging alphabetically from Adams County at 55001 to Wood County at 55141).
Because U.S. Postal Service 5-digit ZIP Codes follow mail carrier delivery routes rather than local government borders, many postal addresses in Wisconsin carry a neighboring city’s mailing name or sit inside a multi-county ZIP Code Tabulation Area (ZCTA). Property tax assessments, deed recording, circuit and county court venue, voter registration precincts, sheriff jurisdiction, and county sales tax rates in Wisconsin are determined by the legal county boundary shown on the map above rather than the postal city name on an envelope.
Land area figures in square miles and internal centroid coordinates (INTPTLAT, INTPTLON) come directly from the U.S. Census Bureau’s current TIGERweb State_County benchmark, while 72 administrative seats and 72 verified official government websites are cross-referenced from Wikidata (CC0).
