ISO country codes are three-letter alphabetic codes assigned to countries and territories by the International Organization for Standardization (ISO) to represent those entities uniquely in various contexts. These codes are used in international trade, communications, and various other fields where a standardized representation of countries is needed. For example, the United States is represented by the ISO country code “USA,” and the United Kingdom is represented by “GBR.”
The ISO 3166 standard defines these country codes. There are several parts to this standard:
- ISO 3166-1: This part defines the two-letter and three-letter country codes, as well as numeric codes, for representing countries and dependent territories.
- ISO 3166-2: This part defines codes for the principal subdivisions (e.g., states, provinces) of all countries coded in ISO 3166-1.
- ISO 3166-3: This part defines codes for former countries, which are no longer in existence.
- ISO 3166-4: This part defines codes for the representation of language, country, and currency names in a standardized manner.
For example, “USA” is the ISO 3166-1 alpha-3 code for the United States, “GBR” is for the United Kingdom, and “DEU” is for Germany.
These codes are widely used in various contexts, including in international shipping, internet domain names, and programming languages for localization and internationalization purposes.
Below is a complete list of all country ISO codes as described in the ISO 3166 international standard.
