Legal Flags

Number plates can show no flag, a national identifier flag or a green flash if it's a zero-emission vehicle.

Flags must be printed to the far left of the plate and must not obscure any of the registration number.

National identifier flags and travelling overseas rules

Another legal option is display any of the following national flags:

  • the Union Flag - the only legal option for overseas driving from 28th September
  • the Cross of St George
  • the Scottish Saltire
  • the Red Dragon of Wales

The flags must be accompanied by one the matching letters:

  • Great Britain or GB
  • United Kingdom or UK - the only legal option for overseas driving from 28th September
  • ENGLAND, England, ENG or Eng
  • SCOTLAND, Scotland, SCO or Sco
  • CYMRU, Cymru, CYM or Cym
  • WALES or Wales

Before September 28th, 2021, if using one of the national identifier flags in Europe, motorists must also display a GB oval sticker on their vehicle.  After that, the oval must show UK, or plates must be the Union Flag plates + UK initials.  More information on this change is available in our news article.

 

Green flash number plates

Zero emissions vehicles can show plates with a green flash in place of a flag.  View our news article for more information.
