What is a county FIPS code?
County FIPS codes are standardized geographic identifiers used in many federal datasets. A county code contains five digits: the first two identify the state or equivalent area, and the last three identify the county or county-equivalent.
For example, Harris County, Texas uses FIPS code 48201. The state portion is 48 for Texas and the county portion is 201 for Harris County.
County-equivalents are included
The Census Bureau uses county-equivalent areas where a state or territory does not use ordinary counties. These can include parishes, boroughs, census areas, independent cities, municipalities, districts, and other legally or statistically equivalent areas.
Frequently asked questions
Is a county FIPS code always five digits?
For county-level identification, yes. Keep leading zeros. For example, Los Angeles County is 06037, not 6037.
Can two counties have the same last three digits?
Yes. The three-digit county portion only becomes unique when combined with the two-digit state FIPS code.
Are FIPS codes useful for Census and government data?
Yes. Geographic identifiers are commonly used to join county records across public datasets, mapping systems, statistical tables, and APIs.
