Buying a private registration is the easy part. Getting it onto the car involves the DVLA, a certificate, a rule about vehicle age and a set of plates from a registered supplier, and the order matters. An online assignment takes effect straight away, and from then on the car cannot be driven until the new plates are on, so the smoothest route is to have the plates ready before you apply. This guide walks through the process from certificate to fitted plates.
Step 1: the certificate
When you buy a private registration, from the DVLA, at a DVLA auction, or from a dealer or private seller, your right to it is held on one of two documents. A V750 certificate of entitlement is issued when a number is bought from the DVLA and has not yet been put on a vehicle. A V778 retention document is issued when a number is taken off a vehicle to be kept. Either one names the person entitled to the registration, and either one is what the DVLA asks for when you assign it. Most dealers will put the number on your car for you; if you would rather do it yourself, ask the dealer for the V750 or V778.
Keep the certificate safe and check its expiry date. A V750 or V778 lasts ten years. Renewing it is free, and you can apply up to 28 days before it expires, but no earlier. Miss the expiry date and the right to the number is lost permanently. The DVLA explains how to renew a private number certificate.
Step 2: the age rule
The DVLA will not assign a private registration that would make a vehicle look newer than it is. A registration with a 26 age identifier cannot go on a car first registered before March 2026, for example. Dateless registrations, which have no year identifier, can go on a vehicle of any age, and that is much of their appeal. Prefix and suffix registrations carry a year letter, so the same rule applies to them: a Y-prefix registration from 2001 cannot go on a car first registered in 1995. No private number can go on a Q-registered vehicle at all. The rules are set out in the DVLA’s guide to assigning a private number, and our guide to the age identifier explains how to read one.
Step 3: order the plates first
A registered supplier can make plates for a private registration as soon as you can show entitlement to it, and a V750 or V778 counts. So order the plates before you assign, and they will be ready when you apply. We need a photo of the V750 or V778 and proof of your identity, such as your driving licence or a recent bill; our guide to the documents we need lists everything we can take. Upload a phone photo of each after you order, with no need to post originals, and we verify them before manufacture.
Check the age rule before you order. The plates are made to your registration, so they are no use if the DVLA will not put that registration on your car.
Plates are typically dispatched within one to two working days once the documents are verified, by free Royal Mail Tracked 48, with the tracking number emailed to you.
Step 4: assigning it through the DVLA
The assignment is done with the DVLA, online or by post, using the vehicle’s V5C and your V750 or V778. It is free: the DVLA’s £80 fee is charged earlier, when a registration is bought from it or taken off a vehicle to be kept. The vehicle must be registered with the DVLA, able to move under its own power and of a type that needs an MOT or heavy goods vehicle test. It must be taxed or have a SORN in place now, and have been taxed or SORN continuously for the past five years. A historic vehicle also needs a current MOT, and the DVLA may ask to inspect the vehicle first.
Who applies depends on the car. If it is registered to you, apply online or by post. If it is a used car you have just bought, wait for the V5C in your name before you apply. If it is brand new, give your V750 or V778 to the dealer and ask them to apply.
If the car already carries a private registration, take that off first. It is a separate £80 DVLA application that puts the number on a V778, and if you assign a new number over it you could lose the right to the old one.
Online assignments usually take effect straight away, unless the DVLA needs to inspect the vehicle. A new V5C follows in the post, usually after about four weeks, and you must not sell the car until it arrives. The car’s original registration is not lost: it normally goes back on the car if you take the private number off later, so keep the old plates.
Step 5: fit the plates before you drive
Until the assignment has gone through, the registration is not yours to display, and driving on the new plates before then is driving on the wrong plates. Once it has gone through, the car must carry the new plates before it is driven again. With the plates ordered first, you can assign online on the day they arrive and fit them before your next journey.
If you assign first, the DVLA’s online service lets you download an eV948 authorisation certificate, which we also accept. It is valid for 3 working days and can only be used once, so send it to us straight away. Otherwise you will be waiting for the new V5C, and the car cannot be driven on its old plates in the meantime.
You must also tell your insurer the new registration, and update any automatic payment accounts, such as for the Congestion Charge, ULEZ, Dart Charge or a Clean Air Zone.
Choosing a finish for a private plate
Many private registrations are shorter than seven characters, and a short plate makes the most of that: the plate is sized to the registration instead of leaving a wide blank space on either side. The plate builder shows any registration in every finish, from Printed at £29.99 a pair to the layered 4D finishes, and on standard, short and hex shapes, so you can see the combination before you order.
If you take the registration off again
Taking a private registration off a vehicle, to keep it for another car or to sell it, is also done through the DVLA. It costs £80, the number goes on a V778 retention document, and if you apply online the car usually goes back to its original registration straight away. You must have the V778 and the new V5C before you sell or scrap the car, or the right to the number is lost. The car then needs plates for its original registration before it is driven. Refit the old plates if you kept them. If not, order new ones with the eV948 you can download after applying online (valid for 3 working days), or with the new V5C when it arrives, which can take 4 to 6 weeks. The DVLA’s guide to taking a private number off has the details.
