A National ANSI File is available for download.
This file contains comma-delimited records for each state and county. The records are of the format:
State Abbreviation, State ANSI, County ANSI, County Name, ANSI Class Code
For example:
FL,12,011,Broward,H1
An ANSI lookup tool for counties and equivalent entities is currently under construction. The FIPS lookup tool is still available, but users must refer to the change notes for updates.
