2001 – today

## Current Style Number Plates Explained

The AB51 CDE system: how the two-digit age identifier works, what the memory tag tells you about where a car was registered, and which letters you will never see.

 **Memory tag**
 Region + office

 **Age identifier**
 Six-month code

 **Random letters**
 Personal element

Two letters for the region, two digits for the six-month period of issue, then three random letters. It is the only format with a numeric age code.

 Where it came from

## History of the format

The current format arrived on 1 September 2001, designed around three goals: more combinations, a clearer age code, and a layout that witnesses could recall more easily. Research had shown people remember the start of a plate best, so the two-letter **memory tag** comes first and encodes the region and DVLA office where the vehicle was first registered.

The **age identifier** follows. From March to August it is simply the last two digits of the year (02, 15, 24). From September to February it is that number plus 50 (52, 65, 74), which is why a car registered in autumn 2023 carries “73”. The three closing letters are random and are the part a private plate buyer personalises.

The system has enough capacity to run until 2050, and because the age code is numeric it is the easiest format to read. It is also the only format where the plate can never go on a vehicle older than the code — which is exactly what makes a well-chosen current-style plate a subtle upgrade rather than a shout.

 Reading the year

## Age identifiers by period

Find the identifier on the plate and read the period straight off. Any vehicle first registered in that period **or later** can carry the plate. Not sure? [Type the registration into the year checker](https://buyprivateplates.uk/number-plate-year-checker/).

 The gaps in the alphabet

## Letters that were never used

The age identifier never uses 01 to 50 as a September code and never 51 to 99 as a March code — so “AB01” does not exist and 51 was the very first. In the random three letters, **I** and **Q** are excluded to avoid confusion with 1 and 0; **Z** is allowed. As a memory-tag first letter, **I** and **Z** remain reserved for Northern Ireland, **Q** for vehicles of indeterminate age, and **J**, **T**, **U** and **X** are unallocated.

 Where the letters point

## Regional codes and memory tags

The first letter of the memory tag is a mnemonic for the region; the second letter narrows it to an office. The full table is below — useful for checking where a used car started life, and for spotting that “LA” on a plate means Wimbledon rather than Lancashire.

| Letter | Mnemonic | Offices |
| --- | --- | --- |
| A | Anglia | AA–AN Peterborough · AO–AU Norwich · AV–AY Ipswich |
| B | Birmingham | BA–BY Birmingham |
| C | Cymru | CA–CO Cardiff · CP–CV Swansea · CW–CY Bangor |
| D | Deeside to Shrewsbury | DA–DK Chester · DL–DY Shrewsbury |
| E | Essex | EA–EY Chelmsford |
| F | Forest & Fens | FA–FP Nottingham · FR–FY Lincoln |
| G | Garden of England | GA–GO Maidstone · GP–GY Brighton |
| H | Hampshire & Dorset | HA–HJ Bournemouth · HK–HY Portsmouth (HW reserved for the Isle of Wight) |
| K | — | KA–KL Borehamwood · KM–KY Luton |
| L | London | LA–LJ Wimbledon · LK–LT Stanmore · LU–LY Sidcup |
| M | Manchester & Merseyside | MA–MY Manchester |
| N | North | NA–NO Newcastle · NP–NY Stockton |
| O | Oxford | OA–OY Oxford |
| P | Preston | PA–PT Preston · PU–PY Carlisle |
| R | Reading | RA–RY Reading |
| S | Scotland | SA–SJ Glasgow · SK–SO Edinburgh · SP–ST Dundee · SU–SW Aberdeen · SX–SY Inverness |
| V | Severn Valley | VA–VY Worcester |
| W | West of England | WA–WJ Exeter · WK Truro · WL–WY Bristol |
| Y | Yorkshire | YA–YK Leeds · YL–YU Sheffield · YV–YY Beverley |

 The one rule that matters

## Which vehicles can carry this format

Read the two digits, convert them to a date with the table above, and the plate can be assigned to any vehicle first registered in that six-month period **or later**. A “19” plate suits any car from March 2019 onward. Buyers often choose a current-style plate that matches or slightly pre-dates their car, keeping the age impression accurate while hiding the exact month.

 From the trade

## Buying tips

- Look for three random letters that spell initials or a short word — that is where the personal value sits.
- A plate whose age code is a little older than your car is legal and often cheaper than a matching one.
- Memory tags that read as words (BOB, GAZ) add a second layer of meaning for little extra money.
- Because every period releases millions of combinations, current-style plates are the most affordable way into a “name” registration.

 Common questions

## Current Style Number Plates Explained: FAQ

**What do the two numbers on a current plate mean?**

The six-month period the vehicle was first registered. March to August uses the year (e.g. 24 for 2024); September to February uses the year plus 50 (74 for autumn 2024).

**What do the first two letters mean?**

The memory tag: the region and DVLA office where the vehicle was first registered. See the table on this page for every code.

**Can I buy a current-style plate for an older car?**

Only if the car was first registered in or after the period the age code represents. A 2015 plate cannot go on a 2012 car.

**Will the current format run out?**

Not for a long time. It has capacity until 2050, at which point DVLA will need a new scheme.
