The FIPS county code is the five-digit Federal Information Processing Standard (FIPS) code which uniquely identifies counties and county equivalents in the United States.  The three-digit number is unique to each individual county within a state, but to be unique within the entire United States, it must be prefixed by the state code. This means that, for example, while Churchill County, Nevada is 001, Alameda County, California and Baker County, Oregon are also 001. To uniquely identify Churchill County, Nevada, one must use the state code of 32 plus the county code of 001; therefore, the unique nationwide identifier for Churchill County, Nevada is 32001. The links in the column FIPS County Code are to the Census Bureau Info page for that county.
