THESE ARE ROAD LEGAL NUMBER PLATES

4D 6mm Number Plates UK

Give your vehicle a bolder raised-number-plate finish with our 4D 6mm Number Plates UK.

Made using precision-cut 6mm raised acrylic characters, these premium 4D plates provide considerably more depth than a conventional printed number plate and a more prominent appearance than our slimmer 3mm 4D option.

Designed for drivers who want their registration to stand out while retaining a clean factory-style layout, our 6mm 4D number plates are manufactured to meet the requirements applicable to road-legal UK registration plates.

Every road-legal plate is made to order using the registration you provide.

Why Choose 6mm 4D Number Plates?

The defining feature of these plates is the 6mm raised acrylic character depth.

Rather than having the registration printed flat onto the reflective plate surface, each letter and number is individually cut from acrylic and applied to create a genuinely raised finish.

Our 6mm option is ideal if you want:

• A deeper raised appearance
• Sharp, precision-cut characters
• More visual impact than 3mm 4D
• A modern gloss-black finish
• Road-legal front and rear number plates
• Replacement plates manufactured to order

The additional character depth makes 4D 6mm plates particularly suited to customers who want the raised style to be clearly noticeable once fitted to the vehicle.

What Does 6mm Mean on 4D Number Plates?

The 6mm measurement refers to the depth of the raised acrylic registration characters.

It does not refer to the thickness of the number plate itself.

The thicker acrylic gives the letters and numbers greater physical depth, helping create the pronounced three-dimensional appearance associated with 6mm 4D number plates.

4D 6mm vs 4D 3mm Number Plates

Both styles use raised acrylic characters, but the most noticeable difference is their depth.

4D 3mm Number Plates use slimmer 3mm raised characters, producing a cleaner and more subtle profile.

4D 6mm Number Plates double that character depth, creating a much stronger raised appearance.

Choose 3mm 4D if you want a lower-profile finish.

Choose 6mm 4D if you want deeper characters and greater visual impact.

This comparison is worth keeping because your main 4D collection already presents the 3mm and 6mm products as distinct options. 

Are 4D 6mm Number Plates Road Legal in the UK?

Yes, raised characters themselves are permitted on UK registration plates. GOV.UK specifically states that number plates may have 3D or raised characters. 

However, road legality depends on the complete number plate, not simply the thickness of the characters.

For modern road-legal plates, requirements include:

• Reflective plate material
• Black characters
• White front background
• Yellow rear background
• Correct character layout and spacing
• Required supplier markings
• Applicable British Standard marking

For plates fitted after 1 September 2021, the relevant British Standard is BS AU 145e, and the characters must be a single shade of black. 

Our road-legal 4D 6mm number plates are manufactured accordingly.

BS AU 145e Compliant 6mm 4D Plates

Road-legal replacement number plates fitted after 1 September 2021 must comply with BS AU 145e.

Your finished plates include the required supplier and British Standard markings and use the appropriate reflective front and rear plate materials.

Raised characters are permitted provided the complete plate continues to meet the relevant requirements.

They’re also suitable when replacing plates that have become:

• Cracked
• Damaged
• Faded
• Delaminated

If you already have 4D plates and want a deeper raised finish, moving from 3mm to 6mm 4D characters also provides a noticeable visual upgrade.

Frequently Asked Questions

What are 4D 6mm number plates?

4D 6mm number plates use individually cut acrylic letters and numbers with approximately 6mm of raised character depth, producing a pronounced three-dimensional appearance.

Are 6mm 4D number plates legal?

Raised characters can be used on road-legal UK number plates. The entire plate must still comply with the relevant requirements for materials, colours, spacing, character design and permanent markings. 

What is the difference between 3mm and 6mm 4D plates?

The primary difference is character depth. A 3mm character has a slimmer profile, while a 6mm character projects further from the plate and therefore produces a more prominent raised effect.

Are 6mm 4D plates thicker than normal number plates?

The 6mm refers to the raised acrylic characters, not the overall backing plate thickness.

Do 4D 6mm plates meet BS AU 145e?

Our road-legal 4D 6mm plates are manufactured to meet the applicable BS AU 145e requirements for modern replacement number plates.

Do I need documentation?

Yes. Registered number plate suppliers must verify appropriate identification and evidence showing you’re entitled to use the registration. 

Can I order shortened 6mm 4D plates?

Where suitable for your registration, select from the available plate-size options while retaining the required legal character spacing and dimensions.

How do I fit 4D 6mm number plates?

Your order includes double-sided 3M mounting tape. Make sure the mounting surface is clean, dry and suitable before fitting.
