This list used to be published by NIST as FIPS 6-4, it is now maintained by the U.S. Census Bureau. See the ANSI Codes for County Subdivisions at https://www.census.gov/library/reference/code-lists/ansi.html#cousub

Usage Note: There are different rules for managing counties in different states. The boundaries of most counties hardly ever change. But in some states county boundaries change often (e.g. Alaska may modify boundaries, eliminate or add counties based on the U.S. census to evenly distribute the population across their counties). So in states where changes are made to counties, the recorded county code may become out of date.
