WHAT ARE 3D NUMBER PLATES?
A 3D number plate is a number plate that has domed effect characters on it, which transforms the plate from being two-dimensional to three-dimensional.
The raised profile effect of 3D plates is what separates them from the rest of the crowd. So, if you’re looking to level up a vehicle's appearance, buying a set of 3D gel number plates can be a great way to do so.


WHAT IS THE DIFFERENCE BETWEEN 3D AND 4D NUMBER PLATES?
Both 3D plate and 4D number plates feature raised characters, however, the main difference between the two styles is the materials used to manufacture them:
- 3D gel number plates are made using polyurethane gel resin;
- 4D number plates are made using solid acrylic.
These manufacturing methods produce two contrasting results, with 3D gel plates having a smooth profile, in comparison to 4D plates that have a “boxy”, precise look to them.
Both types of number plates can enhance the look of your vehicle. Speak to us if you’re unsure about which type you should be considering or would like to add both options to your available styles of number plate on offer.
THE LEGAL REQUIREMENTS FOR 3D GEL NUMBER PLATES
3D gel plates are a popular way to customise a vehicle, but they must comply with strict legal requirements to be road‑legal in the UK. All number plates fitted to vehicles driven on public roads must meet British Standard BS AU 145e and DVLA regulations to ensure visibility, consistency and safety for other road users. While gel plates can be legal, they must follow all the rules below.
- Use of the standard Charles Wright typeface, no custom fonts are allowed
- Characters must be solid black, non‑reflective and properly applied to the plate surface
- Front plates must have a white background and rear plates a yellow background, both fully reflective
- Correct size, spacing and layout of characters as defined in the regulations
- Plates must display the BS AU 145e mark and the supplier’s name and postcode
- No background patterns, tinted colours or any unauthorised symbols
Failure to meet these standards can result in fines, MOT failure or harsher penalties.
