Country codes The following table shows the full list of ISO Country Codes as at March 2003, listed in alphabetical order of country, with some of the most commonly used codes shown at the top.

The zones are the UK, Europe (shown as 'E' below) and Zones 1 and 2. Please close this window when you are finished. |
