List of country codes

A trigramme or trigram (from τρι- "three", γράμμα "letter") is a three-letter code used as a shorthand to designate nations in international sporting events. These codes are generally consistent across different events, but in some cases may differ between events such as the IFCF and Olympic Games. Usually, only the 26 letters in the international basic Latin alphabet can be used in trigrammes, though exceptions may be made for certain events.
