When do you need to display a GB sticker?
Drivers do not need a GB sticker if their number plate includes the GB identifier on its own or with the Union flag.
Vehicles registered in Great Britain or Northern Ireland do not need to display a GB sticker to drive in Ireland.
Drivers must display a GB sticker clearly on the rear of vehicles and trailers if their 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
When driving in Spain, Cyprus or Malta, drivers must display a GB sticker no matter what is on their number plate.
However from 28 September 2021, vehicles registered in the UK must display the letters ‘UK’ when driven abroad (excluding Ireland). All the rules remain the same it is just that “GB” is replaced by “UK”.
