Enter your current registration mark to limit results to registration marks that you can legally assign.

A registration mark must never make a vehicle look newer than it is. The age is carried in the mark itself, so DVLA will not assign one that post-dates the vehicle.

AB76 ABC carries the 76 identifier, which is issued from 1 Sept. 2026. It cannot be assigned to a vehicle first registered as new before that date, though it can go on anything registered on or after it.

A dateless or Northern Irish mark carries no age at all, so it fits a vehicle of any age and is never hidden here.

Why these results?

Prefix private plates. The private plates below start with a single letter followed by a number from 1 to 999 and three letters, like S10 OLK. The first letter decides the oldest vehicle it can go on. Add your vehicle’s current registration mark above to remove registrations you cannot use.

Why these results?

These are shown because the registration mark starts with your initials SO, giving them immediate prominence. The two numbers are the age identifier, followed by three letters, with the strongest matches often featuring your initials again, such as SO11 SAO.

Why these results?

These are selected because SO appears at both ends of the registration mark, creating a balanced or mirrored appearance. We also look for characters in the middle that can be read visually as numbers or letters, producing combinations such as SO11 BSO.

Why these results?

These are prefix-style private plates where your initials SO appear prominently at the end. We prioritise combinations where the preceding characters complement rather than obscure them, such as S13 OSO.
