Find out what the numbers and letters on vehicle registration plates stand for, with information on legal requirements, replacements and personalised plates.
The current registration format is two letters and two numbers followed by three letters.
The first 2 letters are known as a 'DVLA memory tag' and identify where in the UK the vehicle was registered.
The two numbers are known as the 'age identifier'. The first number indicates whether the car was registered in March or September. From 2020 to 2030 the first digit is either 2 (for March) or 7 (for September). . The second number tells us what year the car was made.
The last 3 letters at the end are random.
For example, the number plate CA22 ABC is a vehicle registered in Cardiff, in March 2022.
You can find the full list of memory tag and age identified codes on the DVLA website.
Following the local memory tag and registration date is a space and three letters. This random sequence ensures each vehicle has its own unique identity.
Number plates registered during this time showed the age first, followed by a unique series of three digits specific to that vehicle, then the three-letter local memory tag. Such as A123 ABC.
An 'A' registration means that the vehicle was sold new in August 1983, a 'B' that it was sold new in August 1984 and so on. Until March 1999 new vehicles were only registered annually in August. Registrations from 'T' to 'Y' indicate the six month period they were first registered.
These registrations have the age identifier at the end of the number plate, rather than the start.
So you'd have the three-letter regional identity, the vehicle's unique three-digit number, then the age letter. Such as ABC 123A.
An 'A' registration during this period means the vehicle was sold new in January 1963, a 'B' that it was sold new in January 1964, and so on... The registration year ran from January to December until 1967 when it was moved to August, so 'E' registrations only ran from January 1967 to July 1967.
Personalised number plates can range from convenient standard registrations that happen to include your initials to non-date specific plates such as VIP 1.
There are three key rules for personalised number plates:
Personalised number plates can only be registered with the DVLA using either a V750, V778, V62 or V5C.
You can find out how to register, sell or transfer a personalised plate on the DVLA website.
It's best to buy a personalised plate straight from the DVLA website. Third party companies may add extras fees on top of the cost of the plate.
You can enter a word or letters you want to include on your new plate and then compare number plates to find the one you want.
The price of personalised plates ranges from £250 to hundreds of thousands, so be sure to check as many variations of the plate you want before you buy.
Drivers with personalised number plates should be aware that if their vehicle is stolen or written off then they could be at risk of losing the plate.
Out of the 325 comprehensive car insurance policies listed on Defaqto, only 17 cover the loss of a personalised plate if your car is written off. Exactly how much cover you’ll have depends on the policy – some offer over £5,000, while others only provide up to £2,999.
If your car insurance policy does include cover for personalised number plates and your car is stolen or written off, you'll get a settlement payout to cover the cost of the plate. However, then the insurer owns the vehicle that the registration number is assigned to and therefore owns the rights to the registration number.
You may be able to buy the plate back from your insurer, as long as they haven't already sold it on or destroyed the vehicle.
If your car and personalised plate are stolen, you’ll have to wait six months to get the number plate back and you have to report it stolen to the DVLA. You then have two years and six months to claim it. To reclaim the personalised plate, you’ll also have to prove that the car had a valid MOT and tax at the time of the theft.
If you've damaged or lost your number plate you'll need to find your local DVLA-approved number plate supplier.
To produce the replacement they will need original documentation to prove that you are the owner of the car (such as a V5 document) and proof of your identity and address
There are certain requirements every number plate needs to be legal. They must:
Failure to show your number plate can incur a £1,000 fine and your vehicle will fail its MOT.
Motorbikes only need to display a number plate on the rear.
There are also some rules around the characters on the number plates:
A full list of number plate rules can be found in this DVLA guide.
