Mississippi County Statistics & Summary

How Mississippi Counties and 5-Digit FIPS Codes Work

In U.S. Census Bureau TIGER/Line geography, Mississippi (MS) is assigned the 2-digit state Federal Information Processing Series (FIPS) code 28 and covers 46,925 square miles of land area across 82 counties in the Central Time (CT) zone (with Jackson as the state capital). Every county in the directory above carries a unique 5-digit GEOID formed by combining state prefix 28 with a 3-digit county code (ranging alphabetically from Adams County at 28001 to Yazoo County at 28163).

Because U.S. Postal Service 5-digit ZIP Codes follow mail carrier delivery routes rather than local government borders, many postal addresses in Mississippi 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 Mississippi 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 82 administrative seats and 79 verified official government websites are cross-referenced from Wikidata (CC0).
