How Oregon Counties and 5-Digit FIPS Codes Work
In U.S. Census Bureau TIGER/Line geography, Oregon (OR) is assigned the 2-digit state Federal Information Processing Series (FIPS) code 41 and covers 95,997 square miles of land area across 36 counties in the Pacific Time (PT); most of Malheur County is in Mountain Time (MT) zone (with Salem as the state capital). Every county in the directory above carries a unique 5-digit GEOID formed by combining state prefix 41 with a 3-digit county code (ranging alphabetically from Baker County at 41001 to Yamhill County at 41071).
Because U.S. Postal Service 5-digit ZIP Codes follow mail carrier delivery routes rather than local government borders, many postal addresses in Oregon 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 Oregon 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 36 administrative seats and 34 verified official government websites are cross-referenced from Wikidata (CC0). Need a clean outline worksheet without county labels, or want to verify which Oregon county a specific home or business address sits in?
