FIPS Code Information

  1. The Federal Information Processing Standards (FIPS) Codes are numerical designations used for identifying and reporting purposes as well as case management. Each country, tribal nation, and all of the states and territories in the United States have a five-character identifier code. FIPS codes may also be called locator or location codes.
  2. In the United States, each state has a two-character state identifier code along with a three-character county identifier code. For example, Arizona has a FIPS code of 04.  Maricopa County has a FIPS code of 13. The full FIPS code for Maricopa County, Arizona is 04 013; the FIPS code for Los Angeles County, CA is 06 037.
  3. Tribal FIPS codes are defined by the Bureau of Indian Affairs (BIA).  Their two-character identifier code is always 90, followed by a three-character tribal code designated by the BIA. For example, the FIPS code for the Navajo Nation is 90 780; the FIPS code for the Cherokee Nation is 90 905.
  4. International FIPS codes are defined by the International Standards Organization (ISO).  Their two-character code is always 80 (with the exception of the FIPS codes Canada, which can be found here), followed by a three-character country code identifiers designated by the ISO. For example, the FIPS code for Australia is 80 036; the FIPS code for El Salvador is 80 222.
  5. The Intergovernmental Reference Guide (IRG) contains the FIPS codes of all of the U.S. states and territories, the tribal IV-D agencies, and the foreign reciprocating and Hague treaty countries. The IRG may be accessed through the State Services Portal. 
  6. ATLAS has also added two-digit codes to designate the destination of a payment.  This two-digit code is not part of the federally assigned codes.
