How Louisiana Parishes and 5-Digit FIPS Codes Work
In U.S. Census Bureau TIGER/Line geography, Louisiana (LA) is assigned the 2-digit state Federal Information Processing Series (FIPS) code 22 and covers 43,221 square miles of land area across 64 parishes in the Central Time (CT) zone (with Baton Rouge as the state capital). Every parish in the directory above carries a unique 5-digit GEOID formed by combining state prefix 22 with a 3-digit county code (ranging alphabetically from Acadia Parish at 22001 to Winn Parish at 22127).
Because U.S. Postal Service 5-digit ZIP Codes follow mail carrier delivery routes rather than local government borders, many postal addresses in Louisiana 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 Louisiana are determined by the legal parish 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 64 administrative seats and 59 verified official government websites are cross-referenced from Wikidata (CC0). Need a clean outline worksheet without county labels, or want to verify which Louisiana parish a specific home or business address sits in? Open the Blank Map of Louisiana, 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.
