Please use ONLY the three-letter codes shown against the country. This is generally the “3-Character Country Codes” allocated by the ISO (International Standards Organisation). The list also includes historical ISO Country Codes which have now been withdrawn but are still used for family history purposes. We have also included codes for ‘groups’ of countries (such as South America) which you can use where you do not know the individual country.
DO NOT use the two-letter codes shown in italics in the end column. These are the “2-Character Country Codes” allocated by the ISO. These have been added solely to make this page into a comprehensive reference document which should help you discover what any code you may come across represents.
