Nov
What Are 4D Number Plates?
4D number plates are premium raised acrylic plates, designed using laser-cut solid black characters that sit visibly above the reflective background. They offer a sharper, more defined look than standard printed plates and 3D gel plates.
Also known as:
- 4D acrylic plates
- 4D laser cut plates
- Raised acrylic number plates
- 4D gel / 4D retro number plates
These 4D reg plates are massively trending in 2025 because they’re stylish, legal, durable, and give vehicles a premium upgrade — especially on private registrations.

Are 4D Number Plates Legal?
Yes. 4D number plates are completely legal on UK roads when made to BS AU 145e standards.
To be legal, 4D plates must:
- Use solid black characters (no colours or carbon print)
- Use the correct Charles Wright font and spacing
- Display the supplier name, postcode + BS AU 145e marking
The depth (3mm or 5mm) does not affect legality — spacing and legibility do.
