What do number plates mean?

Ever wondered what the characters on your car registration plate stand for? Read our guide to find the key to decoding number plates and learn about the number plate rules introduced in 2021.

60-second summary

Here’s what you need to know about UK car number plates in a nutshell:

  • UK registration plates are used to identify vehicles so they can be registered, taxed and recognised by police.

  • There have been a few different number plate formats over the years, but the current system has been in place since 2001.

  • You can tell when and where your car was first registered by looking at the ‘age identifier’ characters on your number plate.

  • Registration numbers are allocated by the DVLA, but you can buy a personalised number plate if you want.

  • UK number plates created after September 2021 are subject to strict design rules that govern the font, colour, spacing and national identifying symbols.

  • You could get a fine and your car will fail its MOT if your number plates aren’t displayed properly or are obscured.

  • If your number plate is stolen, you’ll need to report it to the police, your insurance provider and the DVLA, and get a replacement from an authorised dealer.

Why do we have number plates?

Number plates are used to identify vehicles so they can be registered and taxed. They’re also used to identify vehicles for law-enforcement purposes.

Number plates come with the vehicle, not the person who owns it, so when you sell your vehicle the number plate goes with it unless you apply to keep it. Number plates are allocated by the DVLA and officially owned by the Secretary of State.

When did number plates first start?

Number plates were first introduced in the UK as part of the Motor Act of 1903. In the early days of UK licence plates, registration numbers consisted of a single or double letter and a number from 1 to 9999.

Within a few decades, these combinations were all used up as more and more cars hit UK roads, and the format was extended to three numbers and three letters – a system that lasted from 1932 through to the sixties.

Between 1963 and 1965, a new element was added – a letter at the end of the plate that indicated the vehicle’s age. This was moved to the beginning of the plate in 1983 and was followed by three numbers, a serial code and an area code.

This system was replaced by the UK number plate format we recognise today in 2001. The current series of number plates are sometimes called ‘Millennium’ or ‘new-style’ plates.

What do number plate characters mean now?

The number plate registration format we know today was introduced in September 2001. It has three elements:

The DVLA memory tag

  • This is two letters at the beginning of the plate. They identify the region where the vehicle was first registered. There are 19 regions covering England, Scotland and Wales.

  • Northern Ireland uses a different system to the rest of the UK, but it also uses two letters to identify the county where the vehicle was first registered, all of which contain either an I or a Z.

  • I, Q and Z aren’t used in these memory tags in England, Scotland or Wales because they look too similar to other characters and could cause confusion.

  • Q plates are used if a vehicle’s age or identity is in doubt, and may be used for radically modified cars, rebuilt classic cars and kit cars.

The age identifier

  • This is two numbers telling you when the vehicle was first registered. It doesn’t appear on Northern Ireland plates.

  • The age identifier tells you when your vehicle was first registered, within a six-month period.

  • The age identifier for new registration plates changes on 1 March and 1 September every year.

Three randomly generated letters

  • Although it is excluded from the memory tag, Z may be included as a random letter.

  • In Northern Ireland plates can include up to four random numbers.

How can I find out the age of a pre-2001 vehicle?

Cars registered between 1983 and 1 September 2001 used a ‘prefix registration’ format in this sequence:

  • One letter (age identifier) – symbolising the year the car was first registered

  • Random numbers

  • Three letters (area code).

Cars registered between 1963 and 1982 used a ‘suffix registration format’ in this sequence:

  • Three letters (area code)

  • Random numbers

  • One letter (age identifier) – the year the car was first registered.

The car registration years chart below shows how old a car is depending on the suffix (1963-1982) or prefix (1983-2001) formats.

Other ways to check the age of your car

If you don’t fancy decoding your number plate, there are other ways to find out how old it is.

Look in your V5C logbook

The V5C logbook can tell you when the car was first registered. To find out when your car was first registered, go to the ‘Vehicle Details’ section.

Get info on your car directly from DVLA

You can find out a whole heap of interesting information about your car on the DVLA website.

What our expert says...

“Number plate characters have meaning – they can tell you where a car was registered, as well as how old it is. Altering a number plate is against the law, but you can buy your own personalised number plate.”

What’s a personalised number plate?

A personalised plate is one you choose for yourself. Also known as a private number plate, it will often have the characters arranged to spell something like a name or to show a significant date, such as a birthday.

If you’re thinking about getting a private number plate, there are a few factors to bear in mind. For example, if your personalised plate has an age identifier, you can put it on a vehicle of that age or a newer one. But you can’t put it on an older vehicle as this could make it appear newer than it is.

There are also rules about what number plates can say. Combinations spelling out offensive words are banned, for example, as you might expect.

Number plate rules

Plates can’t be altered and there are strict rules on:

  • Fonts

  • The spacing between letters

  • Colours (must have a white background at the front of the vehicle and a yellow background at the back)

  • Letters must be solid and black – two-tone letter styles that are made to look 3D were banned from September 2021

  • The material the number plate is made from must be reflective.

All UK number plates for vehicles registered after September 2021 must now show who supplied the number plate and be marked with a new British Standard Number, for example, ‘BS AU 145e’. The new plates are made from a more durable material that makes them more resistant to damage.

Number plates must only be displayed on the back of motorbikes, if they were registered on or after 1 September 2001. Bikes registered before may also display a number plate on the front, although they don’t have to.

Rules on flags and nationality letters

You can choose to have a flag and identifying nationality letters on your number plate if you want. Permitted flags are:

  • Union flag, known as the Union Jack

  • Cross of St George

  • Cross of St Andrew, known as the Saltire

  • Red Dragon of Wales.

You can show the following national identifier letters, below the flag:

  • UNITED KINGDOM, United Kingdom or UK

  • GREAT BRITAIN, Great Britain or GB

  • CYMRU, Cymru, CYM or Cym

  • ENGLAND, England, ENG, Eng

  • SCOTLAND, Scotland, SCO or Sco

  • WALES or Wales.

It’s vital that you display your number plate correctly. If you don’t, you could be fined as much as £1,000 and your vehicle will fail its MOT.

FAQs

Are Northern Ireland number plates different to the rest of the UK?

Yes, Northern Ireland plates have a different format to the rest of the UK. They show three letters – a serial letter followed by a two-letter code indicating the county – followed by a number sequence of up to four digits.

Northern Ireland number plates don’t indicate the age of the vehicle.

How much does it cost to buy a personalised number plate?

Prices vary widely, but a personalised plate is likely to cost several hundred pounds and possibly even thousands. Some private number plates are available to buy for a fixed price online, but the DVLA also holds regular auctions for its most popular numbers

How do I replace a damaged licence plate?

You can only buy UK number plates from a registered supplier. You can find an authorised number plate dealer in your area using the postcode search tool on GOV.UK. You’ll need to show evidence that you own the vehicle – normally the V5C log book – as well as proof of identity and proof of address.

To get a replacement number plate you’ll need to show evidence that you own the vehicle – normally the V5C log book – as well as proof of identity and address.

It’s an offence to drive with an obscured or illegible licence plate, so if your number plate is damaged and is no longer clear to read, you’ll need to replace it as soon as possible to avoid a fine of up to £1,000.

What should I do if my licence plate is stolen?

If your licence plate is stolen, you should contact the police and your insurance provider as soon as possible and let the DVLA know. Unfortunately, if the police are unable to return your stolen plates, you’ll need to buy a replacement.

What is licence plate cloning?

Licence plate cloning is when criminals copy the registration of a car and use it on a stolen car of the same make, model and colour to make it seem legitimate.

If you start receiving bills or fines that you weren’t responsible for, then you may be a victim of licence plate cloning.

In such a case, you should contact the police, return any fines to the issuer with a letter stating your case, and contact the DVLA in writing with the crime reference number given to you by the police.

What are green number plates?

If you have a zero-emission vehicle you can show off your green credentials with the help of a green number plate. They show a green flash on the left-hand side of the number plate.

Can I have two-tone letters on my licence plate?

According to DVLA rules, vehicles registered after 1 September 2021 must show solid black lettering on their licence plate only. These rules ban the two-tone style that used different shades to give the characters on a registration plate a 3D effect.

This change is designed to make it easier for Automatic Number Plate Recognition (ANPR) cameras to read the registration on UK number plates.

Do I need a number plate for my trailer?

Yes, if you’re towing a trailer, you’ll need to fix a number plate on the back with the same registration number as the vehicle you’re using to tow it.

If your trailer weighs over 3,500kg in gross weight, you may need to register your trailer with the DVLA if you plan on driving it abroad in certain countries in Europe.

Once a trailer has been registered with the DVLA it gets its own unique registration number.
