PCGN works in conjunction with the Foreign, Commonwealth & Development Office (FCDO) to determine the list of country names and official state titles for use by all government departments. Country names usually reflect current British usage. The official state title, (ie. the form used in formal, legal or diplomatic contexts), where different, is shown and reflects the name used by the state itself. It is translated into English where necessary.
The list is arranged alphabetically by country name.
