What this tool does
Look up FIPS codes for all US states and counties
Every US state and county has an official FIPS code, and all of them are here, including DC and the territories.
Search by state name, abbreviation, county name, or FIPS code itself
Search by state name, two-letter abbreviation, county name or the code itself, so it works whichever end you are starting from.
All official 2-digit state and 5-digit county FIPS codes included
State codes are two digits and county codes are five, and both are the official values that census and federal datasets use.
Results as you type
The list narrows with every keystroke rather than waiting for a search button, so finding one county in three thousand takes a second.
Runs fully in your browser with no upload and no sign-up
The whole table is held in the page, so nothing is uploaded and the lookup works with no connection.
Frequently asked questions
What is a FIPS code used for?
FIPS codes appear on US Census Bureau data, CDC health statistics, federal grant applications, USDA reports, tax documents, geographic information systems (GIS), epidemiological tracking, and countless government databases. They provide a standardised numeric ID so different agencies can reliably match data about the same location.
How is a county FIPS code structured?
A 5-digit county FIPS code is the 2-digit state FIPS code followed by a 3-digit county code. For example Los Angeles County, California is 06 (California) + 037 = 06037. The county portion is assigned in rough alphabetical order within each state.
Are FIPS codes the same as ZIP codes?
No. ZIP codes are postal routing codes assigned by USPS and can cross county and state lines. FIPS codes are strictly geographic and administrative - one FIPS code per county, no overlaps.
Is anything uploaded?
No. All data is built into this page and runs entirely in your browser offline.
