A new style for September 2021 registration number plates

September 2021 GB Registration Plate

Along with the age identifier changing to 71 on all cars registered on and after September 1 2021, there’ll be a new standard for UK number plates.

Called ‘BS145e’, this type of registration plate is made from a sturdier material that has better resiliance to damgae, bending and impact. The new plate will also show clearer to ANPR surveillance cameras on UK roads.

The change means that two-tone number plates will no longer be allowed as of September this year. Instead, solid black digits will be a legal requirement on all cars.

On top of this, all number plates will need to show the name of the supplier and postcode in the bottom centre of the number plate. Plus there’ll have to be the plate manufacturer’s name with BS145e in the bottom right corner.


How can I get hold of the new 71 registration plate?

New BMW i4

Quite simply, if you want a car with the new 71 registration plate, then you’ll need to buy a brand-new model that’s been registered between September 1 2021 and March 1 2022.

If you really want to impress your peers, you can look at a brand-new release in September which will come ready with the new reg.


Here are some standout models which are set to be released in September 2021 and are available to order now.

  • BMW i4: a powerful, electric saloon which is based on the 4 Series Gran Coupe due later this year, the iX has a chunky 80kWh battery and powerful 523bhp electric motor for long range and solid performance.
  • BMW iX: as radical as the i3 was when it came along – the BMW iX electric SUV will be BMW’s technology flagship and offer an appealing alternative to the Audi E-tron and Mercedes-Benz EQC.
  • Vauxhall Grandland: just like the brand did with the Mokka and Crossland – the latest Grandland will receive its visually striking ‘Vizor’ front-end which is part of Vauxhall’s promise to deliver a bolder new range.

How does the UK car registration system work?


Have you always wondered what the numbers and letters on a registration plate mean? It is fairly simple process but one that you can use to impress your friends when the pubs finally reopen.

New registration plates September 2021
  • Area Code: The first two letters are regional identifiers and are determined by the area in which your vehicle is registered in. The above example being registered in Birmingham (BA-BY).
  • Age Identifier: This represents the year in which the car was first registered. As there are two new registration periods each year. March’s registrations feature the last two digits of the year, whereas September’s will be the same number plus 50. So the above example was registered in September 2001.
  • Randomly Generated: These three letters are randomly generated and have no meaning.

Every year there are two new car registrations, March and September. From September 1 2021 until March 1 2022, brand-new cars registered in this period will have 71 as their age identifier. This will change to 22 on cars registered after March 1 2022 but before September 1 2023.
