How Indiana Counties and 5-Digit FIPS Codes Work
In U.S. Census Bureau TIGER/Line geography, Indiana (IN) is assigned the 2-digit state Federal Information Processing Series (FIPS) code 18 and covers 35,825 square miles of land area across 92 counties in the Eastern Time (ET); parts of northwest and southwest Indiana are in Central Time (CT) zone (with Indianapolis as the state capital). Every county in the directory above carries a unique 5-digit GEOID formed by combining state prefix 18 with a 3-digit county code (ranging alphabetically from Adams County at 18001 to Whitley County at 18183).
Because U.S. Postal Service 5-digit ZIP Codes follow mail carrier delivery routes rather than local government borders, many postal addresses in Indiana 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 Indiana 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 92 administrative seats and 92 verified official government websites are cross-referenced from Wikidata (CC0). Need a clean outline worksheet without county labels, or want to verify which Indiana county a specific home or business address sits in? Open the Blank Map of Indiana, run a street-segment check on Address to County Lookup, check multi-county postal overlap on ZIP Code to County Lookup, or browse all 50 states on the National U.S. County Map.
