21 Series Registration Plates

Become the owner of a "21" registration number

There are currently some 2,184,209 registrations in the 21 series to choose from. Although you need a vehicle registered on, or after, 1st March 2021 to display a 21 reg on, you don't actually need to be in possession of a suitable vehicle to own a 21 registration plate.

You can purchase a 21 registration and keep it on certificate indefinitely, assigning it to a suitable vehicle in the future, or simply retain it on certificate as an investment.

Select a set of letters below and search for matching 21 series number plates.
