Country Codes ISO 3166 description

This app is based on the ISO 3166-1 system (published by the International Organization for Standartization) and defines a short alphabetic or numeric geographical codes (geocodes) developed to represent countries for use in data processing and communications.


The official name of the standard is Codes for the representation of names of countries - Part 1: Country codes. It defines three sets of country codes:

ISO 3166-1 alpha-2 - two-letter country codes which are the most widely used of the three, and used most prominently for the Internet's country code top-level domains (with a few exceptions).
ISO 3166-1 alpha-3 - three-letter country codes which allow a better visual association between the codes and the country names than the alpha-2 codes.
ISO 3166-1 numeric - three-digit country codes which are identical to those developed and maintained by the United Nations Statistics Division, with the advantage of script (writing system) independence, and hence useful for people or systems using non-Latin scripts.
