⚡ TL;DR — Skip to what matters
Since 28 September 2021, the correct country identifier for UK vehicles abroad is 'UK' — not 'GB'. If your number plate already shows the UK identifier with the Union flag (as most modern UK plates do), you do not need a separate sticker in most countries. However, in Spain, Cyprus and Malta, a UK sticker must always be displayed regardless of what is on your number plate. You never need a sticker or identifier to drive in Ireland.

Why the change from GB to UK?
The 'GB' (Great Britain) identifier on vehicles refers to England, Scotland and Wales — it does not include Northern Ireland. Following the updating of the UK's country identifier under international road traffic conventions, 'UK' is now the correct designation covering the whole of the United Kingdom. The change took effect on 28 September 2021. Vehicles displaying old 'GB' stickers abroad are technically displaying an incorrect identifier — replace them with 'UK' stickers.
Does your number plate replace the sticker?
Most UK number plates issued in recent years show the UK identifier (a Union flag with 'UK') on the left-hand side of the plate. If your plate shows this identifier, you do not need a separate UK sticker in most EU countries — your plate acts as the country identifier.
However, check your specific plate — older UK plates may show 'GB' with a Euro symbol (the blue band with yellow stars), or may have no identifier at all. In these cases, you need a separate UK sticker on the rear of the vehicle.
Country-by-country sticker requirements
| Country | UK sticker required? | Notes |
|---|---|---|
| Ireland (Republic) | No | No identifier required at all |
| Most EU countries | Only if plate lacks UK identifier | Modern plates with UK + Union flag are exempt |
| Spain | Always — regardless of plate | UK sticker must be displayed even with UK identifier plate |
| Cyprus | Always — regardless of plate | UK sticker must be displayed even with UK identifier plate |
| Malta | Always — regardless of plate | UK sticker must be displayed even with UK identifier plate |
| Non-EU (Turkey, Morocco etc.) | Check locally | Rules vary — check gov.uk or destination country embassy |
Trailers and caravans
If you are towing a trailer or caravan, the UK sticker (or identifier requirement) applies to the rear of the trailer as well as the rear of the towing vehicle. The trailer must display its own UK identifier — the vehicle's plate or sticker alone is not sufficient.
Frequently asked questions
I have an old GB sticker — can I just use that?
No — GB stickers are no longer the correct identifier and are not valid internationally since September 2021. You risk a fine in some countries if stopped by police with a GB sticker instead of UK. Replace it with a UK sticker before travelling.
What size should the UK sticker be?
The sticker must be clearly legible. Standard commercial UK stickers meet the international requirements. The letters 'UK' must be in black on a white ellipse. Coloured or novelty stickers (including those with flags other than the Union flag) do not meet the formal requirement — use a standard white/black UK oval sticker if in doubt.
Do motorcycles need a UK sticker?
Yes — the same rules apply to motorcycles. If the motorcycle's plate does not show the UK identifier with Union flag, a UK sticker must be displayed on the rear of the bike. Many older motorcycles have number plates without any country identifier.
I'm driving through multiple EU countries — do the Spain/Cyprus/Malta rules apply only there?
Spain, Cyprus and Malta specifically require a UK sticker regardless of plate. If Spain is on your route, a UK sticker must be visible when driving through Spain. It is simplest to display a UK sticker at all times when driving abroad — it covers all eventualities.
What is the fine for not displaying the correct identifier?
Fines vary by country and at the discretion of the officer. In Spain, driving without the correct country identifier can result in an on-the-spot fine. The amount varies but is typically €90–€200. Carry a UK sticker to avoid this easily preventable penalty.
