from £74.99
Shadow 4D number plates start with a laser-cut 3mm solid black acrylic character on the plate and step a thinner, slightly smaller character on top of it, so each letter and digit has a raised centre with a ledge running round its edge that reads as a shadow in daylight. Sold as a pair (front and rear) for cars and vans, made in County Durham by a DVLA-registered number plate supplier on a reflective BS AU 145e plate. Order before 2pm on a working day with your documents approved and we make them the same day.
How it is made
Two characters are cut on the laser for every position: the full 3mm Charles Wright character, which is bonded to the plate, and a smaller one, 2mm thick, which is bonded to its face with its edge inset all the way round. The visible top sits 5mm above the surface and the ledge below it is the "shadow". Both layers are solid black acrylic on a white front or yellow rear reflective plate that carries our supplier name, postcode and the BS AU 145e mark. Shadow is the reverse of Hover, where the thinner character sits behind the 3mm one and lifts it off the plate; the other layered style is Outline, Retro is shaped rather than layered, and the plain 4D 3mm plate is the single character on its own. Our 4D number plates guide compares every style.
Is it road legal?
Yes, when the finished plate meets BS AU 145e. The stepped top layer is cut from the same solid black acrylic as the character below it, so the plate shows one shade of black on a plain reflective background, with the font, size, spacing and supplier mark the same as on any plate we make. The ledge does not affect readability: what stops a camera reading a plate is tint, a patterned background, a non-standard font or spacing, or damage. Our guide to 3D and 4D number plate legality covers the rules, ANPR and infrared.
A proposed BSI amendment that would stop the production of raised-character plates was consulted on until 13 December 2025 and is still under consideration; nothing has been adopted, BS AU 145e:2018 remains the current standard, and 4D plates remain legal to make, sell and fit. We have not been told when any change would take effect or how plates already fitted would be treated, and we will say so here as soon as we are. Checked 8 September 2026.
Sizes
A standard car plate is 520mm × 111mm. Shadow is also made as a shortened plate cut to your registration with a 16mm margin, a 4x4 square rear plate, an oversize rear plate and a hex plate.
Care
Rinse the plate when you wash the car; a pressure washer at a sensible distance is fine, solvents and abrasive polish are not. See cleaning your 3D or 4D number plates.
Warranty
36 months against manufacturing defects, which covers the plate, the print and the bond between the layers and the plate. It does not cover damage from fitting, impact or chemicals.

Please note we do not dispatch on a Sunday or during Bank Holidays so please adjust your expectations accordingly. We apologise for any inconvenience.
Please note that by law we include our company name, postcode and BSAU number on the plate. The font style for all our plates is Charles Wright which is the legal UK road font, compliant with the law. The DVLA confirm that three-dimensional characters are legal and compliant with road laws, this includes ‘4D’ number plates, as 4D is only an industry standard name, and they are still classed as three-dimensional.
When buying number plates online, the only way to operate fully legally is for the Registered Number Plate Supplier to see the original physical documents in person. If you aren't local to us in County Durham, you will need to send us the documents in the post. The process is simple and the steps to take are explained in depth after you have placed your order. Once we have received your documents, we will produce your number plates and return the documents securely along with the number plates, using a tracked postal service.
The standard UK size for number plates are 520mm by 111mm. Please note this will vary if you opt for a shortened plate option. Shortened plates are cut down to a unique size depending on the length of your registration. Unlike our competitors, we cut these to whichever size you require rather than using pre-made short plates. We produce them to have a 16mm margin on all edges of the number plate, which leaves a nice even clean finish to your plate. If you require a specific size, please state this in the special requests box after clicking purchase. Legally, your number plates cannot have a margin any less than 11mm.
Utopia Plates does not sell show plates, as they could be used on the road, even though the manufacturer may sell them on the basis that they will not be. To avoid this, we will not sell show plates (this includes tinted plates, blank plates or those with non-standard spacing). We will only produce fully road legal plates, with standard spacing (as it appears on your V5C).
