4D Number Plates

Our 4D number plates stand out – literally! 

At Uniplate, we offer high-quality 4D number plates that are produced in line with the BSAU 145e standard. The construction process for a 4D plate is straightforward and easy to implement into your business’ production line. We manufacture our 4D number plates with a PMMA high impact acrylic and oralite reflective sheeting, before applying the high gloss black laser cut 4D digits.

Legislation of 4D plates

4D plates have become a very popular choice of number plates since the legislation came in force in September 2021, with a set of new technical standards. 4D number plates are now road legal, as long as they meet the standards set in place for the other specifications and restrictions outlined by the DVLA. 

This includes but is not limited to: 

  • Character width 
  • Character height  
  • Letter spacing 
  • Size 
  • Colour of characters and plates 
  • Materials used 

We ensure that all the 4D plates we manufacture strictly adhere to these specifications and are made of the strongest and correct materials. At Uniplate, we offer 4D number plates in any size and shape and can also produce number plates in flagged or eco variations.

4D and Uniplate

It’s important to note that it’s a legal requirement to print the vehicle’s registration beneath the acrylic letters so that if ever a letter came loose, the vehicle owner would still have a valid registration.

If you’re a number plate supplier, you can purchase made up 4D number plates or the individual components needed to produce them, by visiting our components page for more information.
