Are 4D Number Plates Legal in the UK in 2026?

4D number plates

4D plates use solid acrylic characters that are laser-cut and bonded onto the face of a reflective UK plate. The name refers to the depth of the character rather than any official classification.

They are road legal when made to the British Standard layout, font and spacing, with the registration displayed correctly. Select Road Legal in the builder and we build to that standard, including the correct character sizes and supplier markings. This applies to 4D 3mm, 4D Bevelled and 4D Gel.

3D Gel number plates

3D Gel plates have raised, domed gel characters with a deep gloss finish. Like 4D, they are road legal when made to the British Standard layout, font and spacing and the registration is displayed correctly — choose Road Legal in the builder.

Ghost number plates — show plate only

Ghost plates use tone-on-tone, low-contrast characters so the registration reads faintly against the plate. Treat ghost plates as show plates only: they are supplied for off-road display, exhibitions and photography, and must not be used on UK public roads.

What we need for road legal plates

After you have ordered and paid we contact you on WhatsApp to collect proof of identity and entitlement to the registration — normally your V5C log book plus photo ID — in line with DVLA requirements. Show plates do not require documents.
