What Does the '71' Plate Mean?
The '71' on a car's registration plate is an age identifier that precisely indicates when the vehicle was first registered in the UK. Specifically, the '71' plate was introduced in September 2021 and applies to all new vehicles registered between September 2021 and the end of February 2022. This two-digit code is crucial for quickly determining a car's age without needing to consult its documentation.
How the Age Identifier Works
The UK's number plate system operates on a biannual cycle, with new age identifiers released twice a year: in March and in September. This ensures that new vehicles registered within these six-month periods carry a distinct marker of their age. The way the numbers are calculated differs slightly depending on the release month:
- March Releases: For vehicles registered between March and August, the age identifier simply uses the last two digits of the year. For example, cars registered in March 2021 received a '21' plate.
- September Releases: This is where the '71' comes in. For vehicles registered between September and February of the following year, the age identifier is calculated by adding 50 to the last two digits of the year. So, for September 2021, the calculation is 21 + 50 = 71. This is why the '71' plate signifies a car registered in late 2021 or early 2022.
This clever system allows the Driver and Vehicle Licensing Agency (DVLA) to continue using a two-digit age identifier without running out of unique codes for many decades. The current format is designed to last until February 2051, at which point the DVLA will likely implement a new system.
The Full Structure of a UK Registration Plate
Beyond the age identifier, a standard UK registration plate (post-2001 format) comprises several elements, each providing specific information about the vehicle. Understanding these components offers a comprehensive insight into a car's origins.
The Local Memory Tag (First Two Letters)
The first two letters on a UK registration plate form what's known as the local memory tag. These letters indicate the regional office where the vehicle was first registered. This can be a useful piece of information for potential buyers, offering a hint about where the car has spent its life, which might influence considerations like local climate or typical driving conditions.
It's important to note that certain letters are intentionally omitted from these memory tags to avoid confusion or undesirable combinations. The letters I, Q, and Z are not used in the memory tag identifiers.
| Letter | Region | DVLA Local Memory Tag Identifier |
|---|---|---|
| A | Anglia | AA-AY |
| B | Birmingham | BA-BY |
| C | Cymru (Wales) | CA-CY |
| D | Deeside to Shrewsbury | DA-DY |
| E | Essex | EA-EY |
| F | Forest & Fens | FA-FY |
| G | Garden of England | GA-GY |
| H | Hampshire & Dorset | HA-HY (HW for Isle of Wight) |
| K | Borehamwood-Northampton | KA-KY |
| L | London | LA-LY |
| M | Manchester & Merseyside | MA-MY (MN, MAN for Isle of Man) |
| N | North | NA-NY |
| O | Oxford | OA-OY |
| P | Preston | PA-PY |
| R | Reading | RA-RY |
| S | Scotland | SA-SY |
| V | Severn Valley | VA-VY |
| W | West of England | WA-WY |
| Y | Yorkshire | YA-YB |
The Random Dealer Indicator (Last Three Letters)
The final three letters on a UK registration plate serve as a dealer indicator. These characters are randomly generated by a computer system once the vehicle has been registered. Before allocation to dealers, they undergo a manual check by human operators to ensure that no offensive or inappropriate word combinations are inadvertently created. This random sequence helps to provide a unique identifier for each vehicle within its registration period and location.
An important exception to this standard structure is personalised registration plates. These bespoke plates allow vehicle owners to pay an additional fee to choose a unique sequence of letters and numbers, often reflecting names, dates, or significant words. While they offer a distinct personal touch, they typically do not conform to the standard age and origin identification rules, as they can be transferred between vehicles.
How the Plate Change Affects You: Buying and Selling
The biannual plate change isn't just a bureaucratic formality; it has tangible implications for both car buyers and sellers. Understanding these dynamics can help you make more informed decisions when it comes to vehicle transactions.
Benefits of Buying a New Car with the Latest Plate
For many, owning a car with the very latest registration plate is highly desirable. A new plate immediately signals that your vehicle is brand new, often implying it's equipped with the newest features, gadgets, and performance enhancements available. This can be a significant draw for car enthusiasts, business professionals, or individuals who simply enjoy showcasing the most current models.

If you're considering a new car, timing your purchase to coincide with a new plate release (March or September) means your vehicle will carry the most current age identifier, potentially making it more desirable at the point of resale compared to a car bought just before a plate change.
Bargains on Used Cars Before a New Plate Release
Conversely, the periods directly preceding a new plate release – typically February and August – can be prime times to snag a bargain on a used car. During these months, car dealerships often experience a slowdown in sales as many buyers hold out for the upcoming new plates. To stimulate sales and clear existing stock, dealers are frequently more amenable to offering better deals, discounts, and greater flexibility during price negotiations. This creates a buyer's market for those looking for a pre-owned vehicle, as dealers are keen to move cars off their forecourts before they are perceived as 'a year older' by the market.
Wise Time to Sell Your Car
The plate change also impacts sellers. Due to the perceived depreciation of older cars when a new batch of vehicles is released, selling your car just before a plate change can be a strategic move. For instance, if you sell your car before the 1st of September, it is still considered to be on the 'previous year's' plate rather than suddenly appearing 'a year older' when the new '71' (or subsequent) plates arrive. This timing can potentially allow you to secure a better resale price for your vehicle, maximising your return before the market adjusts to the introduction of the latest age identifiers.
Frequently Asked Questions About UK Registration Plates
Q: Can I put an older registration plate on a newer car?
A: No, the DVLA regulations strictly prohibit assigning an older registration plate to a newer vehicle. The age identifier on a number plate must always accurately reflect the age of the vehicle, or be newer than the vehicle. This rule is in place to prevent misrepresentation of a vehicle's age.
Q: What if my car has a personalised registration plate? How do I tell its age?
A: If a car has a personalised registration plate, its age cannot be determined by the plate itself, as these plates do not follow the standard age identifier system. To find the car's true age, you would need to check its Vehicle Registration Document (V5C logbook) or conduct an online vehicle check using its Vehicle Identification Number (VIN).
Q: When do new registration plates typically come out in the UK?
A: New registration plates are released twice a year in the UK: on the 1st of March and the 1st of September. For example, '21' plates were released in March 2021, and '71' plates in September 2021.
Q: Are all letters and numbers used on UK plates?
A: Not all letters are used. The letters 'I', 'Q', and 'Z' are generally avoided in the local memory tag part of the plate to prevent confusion (e.g., 'I' looking like '1') or specific uses ('Q' for vehicles of indeterminate age, 'Z' for specific purposes). Numbers 0 and 1 are used, but their appearance must be distinct from letters like 'O' and 'I'.
Q: How long will the current UK registration plate system last?
A: The current system, introduced in September 2001, is designed to continue until February 2051. At that point, the DVLA will need to devise a new format for registration plates.
Conclusion
The '71' on a car registration plate is far more than just a random number; it's a precise indicator of a vehicle's birth quarter in the UK, signifying registration between September 2021 and February 2022. Understanding the full structure of UK number plates – from the local memory tag identifying the region of origin to the dealer indicator and the all-important age identifier – equips you with valuable knowledge. This insight can prove incredibly beneficial whether you're navigating the process of buying a new or used car, or looking to sell your current vehicle, allowing you to leverage the biannual plate change to your advantage.
