Intergovernmental Reference Guide (IRG)
The Intergovernmental Reference Guide (IRG) offers access to resource information for the child support community as well as the public. It provides

The IRG also contains Federal Information Processing (FIPS) codes for states, Bureau of Indian Affairs (BIA) codes for tribes, and International Standards Organization (ISO) codes for international countries, used as identifiers in child support activities.
