Tribes Services

EPA provides three tribal data services to make it easy to comply with the Tribal Identifier Data Standard:

  • Tribes Names Service is the EPA tribal web service Software system designed to support interoperable machine-to-machine interaction over a network. It may use one of several technologies, including SOAP and REST. for non-geospatial systems. It automatically maintains accurate and current tribal information like current tribal names, BIA codes, EPA Internal Identifiers, and associated EPA regions.
  • Tribal Areas Service is the EPA tribal web service Software system designed to support interoperable machine-to-machine interaction over a network. It may use one of several technologies, including SOAP and REST. for geospatial systems. It includes geospatial data, current tribal names, BIA codes, and EPA Internal Identifiers.
  • Tribe Entity Mapping Spreadsheet (xlsx) (179.97 KB, 01/31/2025) is an Excel document that contains current and historic tribal data like tribal names, BIA codes, EPA Internal Identifiers, associated EPA regions, and lead EPA regions. 

Data provided by these services are regularly updated. Tribal names are obtained from BIA’s official list of federally recognized tribes that is published at least annually in the Federal Register The official daily publication for rules, proposed rules, and notices of federal agencies and organizations, as well as executive orders and other presidential documents. Access the FR online (https://www.govinfo.gov/).. The Tribes Services apply a unique EPA Internal Identifier to each tribe. This ensures the correct identification of tribal partners and can be used to identify name changes over time. EPA Internal Identifiers are more reliable and available that BIA codes, which are not currently provided for Alaska Native entities and some American Indian entities.
