American National Standards Institute (ANSI), Federal Information Processing Series (FIPS), and Other Standardized Geographic Codes
American National Standards Institute (ANSI), Federal Information Processing Series (FIPS), and Other Standardized Geographic Codes
American National Standards Institute (ANSI) codes are standardized numeric or alphabetic codes whose documentation is issued by ANSI to ensure uniform identification of geographic entities through all government agencies. ANSI oversees the issuance of the following two code series used by the Census Bureau: 1) InterNational Committee for Information Technology Standards (INCITS) codes, and 2) Geographic Names Information System (GNIS) codes. INCITS codes are formerly known as Federal Information Processing Standards (FIPS) codes. GNIS codes, referred to as the National Standards (NS) codes, were established by the United States Geological Survey (USGS) and are assigned by them with INCITS and ANSI oversight. The Census Bureau also assigns and issues codes for a number of geographic entities for which INCITS or GNIS codes are not available, and sometimes in addition to INCITS and GNIS codes.
The majority of the tables included on this webpage provide INCITS and GNIS codes, but there are four exceptions:
- The American Indian areas table provides 4-digit codes assigned and maintained by the Census Bureau.
- The county subdivisions and places tables provide the 5-digit Federal Information Processing Series (FIPS) codes, formerly referred to as FIPS55, assigned and maintained by the Census Bureau.
- The school district table provide the local education agency (LEA) codes assigned by the U.S. Department of Education.
- The voting district table includes codes assigned by individual states.
The USGS provides a tool for searching the Geographic Names Information System for National Standards codes. It is linked to under "Other Resources" below.
