South Carolina County Statistics & Summary

How South Carolina Counties and 5-Digit FIPS Codes Work

In U.S. Census Bureau TIGER/Line geography, South Carolina (SC) is assigned the 2-digit state Federal Information Processing Series (FIPS) code 45 and covers 30,064 square miles of land area across 46 counties in the Eastern Time (ET) zone (with Columbia as the state capital). Every county in the directory above carries a unique 5-digit GEOID formed by combining state prefix 45 with a 3-digit county code (ranging alphabetically from Abbeville County at 45001 to York County at 45091).

Because U.S. Postal Service 5-digit ZIP Codes follow mail carrier delivery routes rather than local government borders, many postal addresses in South Carolina 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 South Carolina 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 46 administrative seats and 45 verified official government websites are cross-referenced from Wikidata (CC0).
