This question already has an answer here:
Are there any web services or DBs available that will be able to return the ISO 3166-1 and ISO 3166-2 (Country & region) codes given a particular address or latitude/longitude coordinates?
I'm currently using the Google Geocode API in a PHP app, and would like to augment that info with the above mentioned ISO codes.
Thanks very much.
