How Michigan Counties and 5-Digit FIPS Codes Work
In U.S. Census Bureau TIGER/Line geography, Michigan (MI) is assigned the 2-digit state Federal Information Processing Series (FIPS) code 26 and covers 56,613 square miles of land area across 83 counties in the Eastern Time (ET); four Upper Peninsula counties bordering Wisconsin are in Central Time (CT) zone (with Lansing as the state capital). Every county in the directory above carries a unique 5-digit GEOID formed by combining state prefix 26 with a 3-digit county code (ranging alphabetically from Alcona County at 26001 to Wexford County at 26165).
Because U.S. Postal Service 5-digit ZIP Codes follow mail carrier delivery routes rather than local government borders, many postal addresses in Michigan 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 Michigan 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 83 administrative seats and 83 verified official government websites are cross-referenced from Wikidata (CC0). Need a clean outline worksheet without county labels, or want to verify which Michigan county a specific home or business address sits in?
