Do you need a passport to go to Jersey?
Jersey is part of the Common Travel Area, therefore if you’re a British Citizen you do not need a passport to travel to Jersey in the Channel Islands as there are no formal immigration controls.
The Common Travel Area is an agreement between the UK, the Crown Dependencies (Bailiwick of Jersey, Bailiwick of Guernsey, and the Isle of Man) and Ireland which allows citizens residing in these locations to move freely between one another.
