Ever wondered how the UK number plate system works? Understanding number plates can help you identify a vehicle’s age, registration location, and even help when valuing a car.
Number Plates Explained
New vehicle registrations are released twice each year in the UK — in March and September. These registration updates often coincide with the release of new vehicle models and updated designs from manufacturers.
The current number plate system was introduced in September 2001 and follows a standard format:
Two letters – Two numbers – Three letters
For example:
AB22 CDE
Each section of the plate has a specific meaning.
What Do the Numbers Mean?
The two numbers in the middle of the registration identify the vehicle’s age.
March Registrations
Cars registered between March and August use the current year.
For example:
- 16 plate = March 2016
- 24 plate = March 2024
September Registrations
Cars registered between September and February use the current year plus 50.
For example:
- 66 plate = September 2016
- 74 plate = September 2024
This system helps quickly identify when a vehicle was first registered.

What Do the Letters Mean?
The first two letters on the number plate are called the local memory tag.
These letters identify where the vehicle was originally registered.
- The first letter represents the region
- The second letter identifies the DVLA registration office
For example, vehicles registered in London commonly begin with:
- LA
- LB
- LC
- LY
Interestingly, the letter Z is not used in regional area codes and is typically reserved for random allocation purposes.
What Do the Last Three Letters Mean?
The final three letters are randomly assigned when the vehicle is first registered.
These characters help make each registration unique and are usually allocated in batches to dealerships during the registration process.
Why Number Plates Matter
Vehicle registration plates can reveal useful information about a car’s age and registration history.
They are also commonly used when:
- Checking vehicle details
- Getting insurance quotes
- Obtaining MOT information
- Valuing a vehicle online
