What is a FIPS number? Know more about FIPS codes

For identifying geographic areas in USA there are a lot of different instruments, including FIPS numbers. In this article you will know what it is.

What does FIPS code mean?

FIPS is the abbreviation of the term “Federal Information Processing System” (FIPS), which used to designate a specific county or state. FIPS codes look like the combinations of numbers, which match with exact geographic areas.

By the number of digits in FIPS codes you can determine the level of geography:

  • State-level FIPS codes consist of 2 digits.
  • County-level FIPS codes consist of 5 digits.

FIPS code example

FIPS county codes combination always starts with 2 digits of FIPS state codes (of the state to which the county belongs). Example: county FIPS code of Jackson County is 01071. It means that it is situated in the state with FIPS code 01 i.e in Alabama.

ZIP codes and FIPS codes — what’s difference?

FIPS code is a term that is used in a broader sense than ZIP Codes have. Each county has only one own FIPS code, while containing dozens of ZIP Codes.

By the way, there is a big difference in classification principle:

  • FIPS codes usually appear in alphabet order (within a state if we speak about county FIPS codes). County-level FIPS codes are often (but not always) odd numbers, so that new or changed county names can be fit in their alphabetical sequence slot.
  • ZIP codes are formed in another way. The database is just the list of mail delivery routes that the USPS uses to organize delivery processes.
