What UK number plates show and how to read them

A UK number plate contains seven characters that tell you when the car was registered and where. The format is two letters, two numbers, and three letters — for example, AB12 CDE. The two numbers in the middle are the key: they show the registration month and year. The first number is the decade (0 for 2000–2009, 1 for 2010–2019, 2 for 2020–2029), and the second number shows which half of the year: 0 or 1 for March to August, 5 or 6 for September to February.

The first two letters identify the local DVLA office where the vehicle was registered. AB is Anglia, BA is Birmingham, BN is Brighton, and so on. These letters no longer reflect where the owner lives — you can register a car anywhere — but they remain on the plate. The final three letters are random and have no meaning beyond making each plate unique.

Older plates use a different format: three letters followed by up to three numbers, then one or two letters at the end (for example, ABC 123 DE). These were issued before 2001 and the numbers show the year of first registration. A plate ending in a single letter was issued between 1963 and 1983; two letters means 1983 to 2001.

Key Takeaways

  • The two numbers in the middle of a modern UK plate show the registration month and year in a specific code: the first digit is the decade, the second is the half-year.
  • The first two letters show which DVLA office processed the registration, not where the owner lives.
  • Plates issued before 2001 use an older format with the year shown differently, and you can identify the age by counting the letters at the end.
  • Personalised plates (also called private or cherished plates) can display almost any combination of letters and numbers, but must still follow DVLA rules and cannot be offensive or misleading.
  • When you sell a car, you can transfer the plate to another vehicle, keep it on a retention document, or leave it with the car for the new owner to use.

How the registration numbers work in detail

The two-digit code in the middle of the plate is the most useful part for dating a vehicle. The first digit represents the decade: 0 or 1 for the 2000s, 2 or 3 for the 2010s, 4 or 5 for the 2020s, and so on. The second digit shows which half of the year: 03, 04, 05, 06, 07, 08 for March to August, or 53, 54, 55, 56, 57, 58 for September to February.

So a plate reading AB08 CDE was registered between March and August 2008. A plate reading AB58 CDE was registered between September 2008 and February 2009. This system has run since 2001 and repeats every 20 years, so a plate with 28 in the middle could be from 2028 or theoretically from 2008 — but the condition of the car and other documents would confirm the actual year.

The DVLA introduced this system to replace the older letter-based age identifier, which used a single letter at the end of the plate (A for 1983, B for 1984, and so on, cycling through the alphabet). That system ran from 1963 to 2001 and made it very straightforward to spot a car's age at a glance, but it also meant all cars registered in the same month had the same letter, which limited the number of unique plates available.

Personalised and private plates

A personalised plate (also called a private or cherished plate) is a registration number that does not follow the standard format or that spells out a word or name. You can buy these from the DVLA or from private dealers who hold them. Common examples include plates that spell initials, dates of birth, or words — though the DVLA has strict rules about what is allowed.

The DVLA will not issue a plate that is offensive, that impersonates a government vehicle, that could be misleading (such as looking like a police car), or that breaches copyright. Plates must still contain at least two letters and two numbers to be legal on UK roads. You cannot use a plate that looks too similar to a standard registration, as this could confuse enforcement cameras.

Personalised plates cost between £250 and several thousand pounds depending on how desirable the combination is. You can transfer a personalised plate to a new car, or you can put it on a retention document (held by the DVLA) for up to ten years while you own a different vehicle, then transfer it back later. If you sell a personalised plate to someone else, the DVLA handles the transfer and charges a fee.

What happens to your plate when you sell the car

When you sell a vehicle, you have three options for the registration plate. You can leave it with the car for the new owner to use — this is the simplest route and requires no action from you beyond telling the DVLA you have sold the vehicle. You can transfer the plate to a different car you own by notifying the DVLA and paying a small fee. Or you can keep the plate by putting it on a retention document, which preserves your right to use it on a future vehicle.

To transfer a plate between your own vehicles, you need the V5C registration document (the logbook) for both cars, and you must notify the DVLA using form V317. The process takes a few weeks. If you want to keep a plate without using it, you explore for a retention document using form V750, which costs money and is valid for ten years. After ten years, if you have not transferred the plate to a vehicle, it returns to the DVLA and becomes available for others to buy.

If you are buying a car with a personalised plate that you want to keep, make sure the seller has the retention document or that they transfer the plate to you formally through the DVLA. A plate is not yours just because it is on the car — the registration document shows who owns it.

Displaying your plate correctly

UK law requires that your number plate is clearly visible, not obscured by dirt, damage, or objects. The characters must be in black on a white background (for the front plate) or white on black (for the rear plate). The font is standardized — you cannot use a different typeface or spacing to make letters look like numbers or vice versa, as this is illegal and can result in a fine.

The plate must be mounted flat and at an angle no greater than 30 degrees from vertical. It cannot be bent, cracked, or faded to the point where characters are hard to read. If your plate is damaged, you can order a replacement from the DVLA or from an approved number plate supplier. The DVLA does not issue physical plates itself — it issues the registration, and you buy the physical plate from a supplier and fit it yourself or have a garage do it.

Covers, frames, or anything else that obscures any part of the plate are illegal, even if they are transparent. This includes covers that claim to prevent speed camera detection — these are illegal and can result in prosecution. The only legal addition is a small EU flag or national identifier on the left side of the plate (showing the UK flag or country code), which is optional.

Plates for different vehicle types

Motorcycles, mopeds, and three-wheelers have smaller plates than cars, and the format is the same but the physical size is different. Motorcycles use a vertical plate (taller than it is wide), while cars use a horizontal plate. Trailers have their own registration plates and do not share the towing vehicle's number.

Historic vehicles (generally those over 40 years old) can display a plate in the old format if the owner chooses, or they can use a modern plate. Some owners of classic cars prefer the older style for authenticity. The DVLA allows this, and you can explore to use a historic plate format if your vehicle qualifies.

Vehicles registered in Northern Ireland have a slightly different format: they use the letters GB or NI at the left, followed by the standard seven-character registration. Plates from Northern Ireland are legal throughout the UK, and UK plates are legal in Northern Ireland.

Reading plates from other countries

If you see a car with a non-UK plate, the format varies by country. European plates are typically longer and narrower than UK plates, and they show a country code on the left (D for Germany, F for France, NL for Netherlands, and so on). The format and what the numbers mean differ by country — there is no universal system.

A car with a foreign plate can be driven in the UK temporarily (usually for up to six months), but if it is to be kept permanently in the UK, it must be registered with the DVLA and given a UK plate. The DVLA will not allow a foreign plate to be the permanent registration for a vehicle based in the UK.

Frequently Asked Questions

How do I know what year a car was registered from its plate?

Look at the two numbers in the middle of the plate. The first digit is the decade (0–1 for 2000s, 2–3 for 2010s, 4–5 for 2020s). The second digit shows the half-year: 03–08 for March to August, 53–58 for September to February. So 15 means September 2015 to February 2016. For plates older than 2001, count the letters at the end: one letter means 1963–1983, two letters means 1983–2001.

Can I change my number plate to a personalised one?

Yes. You can buy a personalised plate from the DVLA or from a private dealer. The DVLA charges a one-off fee (currently £250 for a standard personalised plate), and you can then use that plate on any vehicle you own. You must notify the DVLA of the change, and the process takes a few weeks. The plate must still follow DVLA rules — it cannot be offensive or misleading.

What if my number plate is damaged or faded?

You can order a replacement from an approved number plate supplier — the DVLA does not issue physical plates. You fit it yourself or have a garage do it. The registration number stays the same; you are just replacing the physical plate. If the plate is so damaged that characters are unreadable, you should replace it promptly, as driving with an illegible plate can result in a fine.

Do I have to transfer my plate when I sell my car?

No. You can leave the plate with the car for the new owner to use, or you can transfer it to another vehicle you own, or you can keep it on a retention document for up to ten years. If you do nothing, the plate stays with the car. To transfer it or retain it, you must notify the DVLA using the appropriate form.

Can I use a plate from another country if I move to the UK?

You can drive with a foreign plate temporarily (usually up to six months), but if you are keeping the car in the UK permanently, you must register it with the DVLA and get a UK plate. The DVLA will not allow a foreign plate as a permanent registration for a UK-based vehicle.
