## United Kingdom (UK)

This was historically called the United Kingdom of Great Britain and Ireland (1801–1922) after which it became the United Kingdom of Great Britain and Northern Ireland or UK for short.
It has never been a philatelic term, any more than England has, because the worldwide consensus among philatelists and postal authorities has been that the issuer of British stamps is called Great Britain.
