No for GB. Yes for UK

Motorists must remove any GB stickers or magnets from their number plates when driving in Europe, according to a new law.

From today (Tuesday, September 28) road users will instead have to use a UK sticker, to represent the change in identifying British vehicles whilst abroad from 'GB' to 'UK'.

If a number plate has any kind of GB identifier - the Union Jack, a Euro symbol, a national flag of England, Scotland or Wales, or numbers and letters - a UK sticker is additionally required.

The update has been outlined by the United Nations, which said it had received "a notification that the United Kingdom is changing the distinguishing sign that it had previously selected for display in international traffic on vehicles registered in the United Kingdom, from 'GB' to 'UK'".
