National flags on number plates are optional, popular and, unusually for plate styling, fully legal when done correctly. The rules are specific about which flags are permitted, which letters can accompany them and where they go. Here is the complete picture.
The four permitted flags
A road legal UK number plate may display one of the following flags, accompanied by a permitted national identifier:
- The Union flag, with UK, United Kingdom, GB or Great Britain
- The Cross of St George, with ENG or England
- The Cross of St Andrew, the Saltire, with SCO or Scotland
- The Red Dragon of Wales, with CYM, Cymru, WALES or Wales
Zero emission vehicles may additionally display the green flash panel, which sits in the same position at the left hand end.
Where the flag goes
The flag and identifier occupy a band at the left hand end of the plate, ahead of the registration characters. The flag sits above the letters. The panel must not intrude on the registration or eat into the required margin around the characters.
Note that the identifier band is not a general purpose sticker area. Only the permitted combinations above are allowed.
What is not permitted
- Flags of other countries, including the Irish tricolour and EU member state flags
- The EU flag and the old Euro band with country letters, on plates supplied now
- County and regional flags, such as Yorkshire or Cornwall
- Football club crests, manufacturer logos and club badges
- Any flag placed on the right hand side of the plate
- Any identifier letters not on the permitted list
Do you have to display a flag?
No. Flags and national identifiers are entirely optional on a UK number plate. A plate with no flag panel at all is perfectly legal, and it gives you slightly more width to work with on shorter plates.
Flags and driving abroad
This is where the choice becomes practical rather than decorative. When taking a UK registered vehicle to Europe, a plate displaying the UK identifier with the Union flag generally removes the need for a separate UK sticker. A plate showing a GB identifier, a Euro symbol, one of the national flags of England, Scotland or Wales, or nothing but characters, means you need to display a UK sticker on the rear.
There is an exception worth remembering. In Spain, Cyprus and Malta you must display a UK sticker regardless of what appears on the plate. Always check current guidance before you travel, since requirements can change.
Choosing between them
If you travel to Europe regularly, the Union flag with UK is the most practical choice. If the car never leaves the country, pick whichever identity you prefer. Many owners match the flag colour to the vehicle, which works particularly well with a colour matched border.
You can add any permitted flag to our standard plates, 3D gel plates or 4D plates.
Frequently asked questions
Can I have a different flag on the front and rear?
Each plate must be individually compliant, but there is no requirement for them to match. Most people keep them the same.
Is the old GB Euro plate still legal?
Existing plates are not automatically unlawful, but the Euro symbol no longer serves its original purpose and will not exempt you from displaying a UK sticker abroad. New plates should use a permitted UK identifier.
Can I have a flag on a motorcycle plate?
Space is tight on a reduced size plate, and the registration and margins take priority. Ask us what will fit before ordering.
Can I add a flag that is not on the permitted list?
Not on a road legal plate. Only the four permitted flags and their identifier letters may appear on a vehicle used on a public road.
