The geoip_region_name_by_code() function will return the region name corresponding to a country and region code combo.
In the United States, the region code corresponds to the two-letter abbreviation of each state. In Canada, the region code corresponds to the two-letter province or territory code as attributed by Canada Post.
For the rest of the world, GeoIP uses FIPS 10-4 codes to represent regions. You can check » http://www.maxmind.com/app/fips10_4 for a detailed list of FIPS 10-4 codes.
This function is always available if using GeoIP Library version 1.4.1 or newer. The data is taken directly from the GeoIP Library and not from any database.

The two-letter (or digit) region code (see geoip_region_by_name())
Returns the region name on success, or FALSE if the country and region code combo cannot be found.
