ISO 3166-1 decoding table

This decoding table provides the user of ISO 3166-1 with an easy access to the definition of all 676 code elements available in the alpha-2 code of ISO's country code standard.

The content of this document is taken from two sources: The official code list of ISO 3166-1 and the list of reserved ISO 3166-1 code elements which contains information on code allocations which are not officially part of ISO 3166-1 (see "Reserved code elements"). The reserved code elements have different statuses with regard to restrictions on use within ISO's country code system. Some may be used - others must not be used.

These statuses - and their approximate meanings for the user of ISO 3166-1 - are described and colour-coded in Table 1. Tables 2 gives a colour coded, clickable matrix of all ISO 3166-1 alpha-2 code elements which is linked to Table 3 which gives the definition of the code element.

For more detailed information please refer to the section on "Reserved code elements" on our Website.
