About FipsDecoder.com

FipsDecoder.com is a free reference tool for FIPS codes — the Federal Information Processing Standard codes assigned to US states, counties, congressional districts, metropolitan areas, and other geographic units by the US Census Bureau.

Each FIPS code page explains what the code identifies, its geographic coverage, and related codes. Data is sourced from the US Census Bureau ANSI/FIPS reference files, which are public domain.

This site is operated by Long Pattern LLC. We build reference tools on top of publicly available government datasets. FipsDecoder.com is not affiliated with the US Census Bureau or any government agency.
