As the Brexit Transition Period has now finished vehicles with UK number plates have new GB sticker requirements

If you’re in Spain, Cyprus or Malta, you must display a GB sticker no matter what is on your number plate.

In EU Countries other than the 3 mentioned above you do not need a GB sticker if your number plate includes the GB identifier on its own or with the Union flag.

You do not need to display a GB sticker to drive in Ireland.

Apart from the 3 countries mention above you must display a GB sticker clearly on the rear of your vehicle if your number plate has any of the following:

A Euro symbol

A national flag of England, Scotland or Wales

Numbers and letters only – no flag or identifier
