How Oklahoma Counties and 5-Digit FIPS Codes Work
In U.S. Census Bureau TIGER/Line geography, Oklahoma (OK) is assigned the 2-digit state Federal Information Processing Series (FIPS) code 40 and covers 68,597 square miles of land area across 77 counties in the Central Time (CT) zone (with Oklahoma City as the state capital). Every county in the directory above carries a unique 5-digit GEOID formed by combining state prefix 40 with a 3-digit county code (ranging alphabetically from Adair County at 40001 to Woodward County at 40153).
Because U.S. Postal Service 5-digit ZIP Codes follow mail carrier delivery routes rather than local government borders, many postal addresses in Oklahoma 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 Oklahoma 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 77 administrative seats and 58 verified official government websites are cross-referenced from Wikidata (CC0). Need a clean outline worksheet without county labels, or want to verify which Oklahoma county a specific home or business address sits in?
