2 Letter Country Codes

Postby hairyal on Thu Mar 01, 2007 8:12 am


Just wondering if the two letter country codes (e.g. US for the United States) given by api.hostip.info/country.php follow any particular standard, or if they are proprietary. I thought perhaps they might follow ISO 3166-1 alpha-2, but was hoping for confirmation/denial of this.

Generally, yes, it's ISO3166. But there are specific cases where obsolete or invalid codes are used, largely because the source of the information (the various NICs or the netblock owner) don't validate or update it.

Examples: AP (Asia Pacific), EU (European Union), UK (instead of GB), YU, etc.

Cool - I had noticed GB, hence the question. Do you have a complete list of which codes don't match the ISO standard?

Try this: http://www.iana.org/root-whois/index.html

They keep a current list of country codes.
