A plate viewer is an online preview tool that shows how a registration would look on a car before you buy or order it, and a show plate is a display-only plate that is not legal to use on a public road in place of your proper plates. Both involve the same registration number, but they have very different legal standing: a preview is a picture, a show plate is a prop, and only a plate made to the British Standard by a registered supplier counts on the road.
Part of Personalised Number Plates. Start with the main guide: Cherished Plates: What They Are and How They Work
Updated October 2026 · Independent information, not legal advice
Whether you are choosing a personalised number plate, planning an event display or just curious how a combination reads, the useful questions are what a preview can and cannot tell you, what a show plate is for, and which plates you must actually fit. Keeping the three apart avoids expensive mistakes.
What Is A Plate Viewer?
A plate viewer is a visual tool, usually a web page from a plate seller or broker, that places a typed registration over an image of a vehicle. It helps you imagine the result and nothing more.
Is a number plate viewer official?
No. The Driver and Vehicle Licensing Agency (DVLA) issues registrations and records them, but it does not run a mock-up service. A number plate viewer is a commercial convenience.
What does a number plate visualiser do?
A number plate visualiser renders letters and numbers on a plate shape, sometimes on a photo of a car in a chosen colour. Treat the picture as an impression, not proof of legality.
How Will A Number Plate Look On My Car?
To see how will number plate look on my car, enter the characters, choose a vehicle shape that resembles yours and compare front and rear. The result is approximate, because colour, camera angle and bumper shape vary.
What should you check in the preview?
Check the readability of the characters, how a long combination fits the plate area and whether any letters could be misread.
- Look at each letter next to its neighbours.
- Consider how it reads at a distance.
- Compare the white front and the yellow rear.
- Think about how the space for the plate varies by vehicle.
Why can the preview differ from the real thing?
Previews may use idealised spacing and fonts. A legal plate must follow the fixed typeface and spacing, so the finished plate can look slightly different from a free-style mock-up.
Can You View A Registration Plate On A Car Before Buying?
A mock-up lets you view registration plate on car images in different colours and shapes, which is more useful than imagining the characters on paper.
You can view a registration plate on a car through a seller's mock-up before you pay, which is a sensible step when the combination is distinctive or very short.
What is a number plate on car viewer good for?
A number plate on car viewer is good for judging how a name-like or word-like registration reads. It is not designed to confirm the number is available or that the car qualifies to display it.
Does a preview confirm availability?
No. Availability comes from the DVLA's stock or from the seller who holds the number. The personalised number plates overview explains how numbers are bought.
What Is A Car Plate Viewer?
A car plate viewer may mean a mock-up tool, but people also use the phrase for a way of seeing details about the vehicle that already wears a plate. Those two needs are different.
Is it the same as a number plate check?
No. A mock-up shows how letters might look. The free number plate check looks up an existing vehicle record and shows make, model, colour, fuel and MOT and tax status.
What Are Show Plates?
Show plates let you display registration plates on a wall, a stand or a gift, and a seller may offer to show registration plates with your chosen characters as a keepsake. Whatever the use, number plates show plates are decorative objects and never a substitute for the legal pair on the vehicle.
Show plates are plates made for display, such as at car shows, in photographs, on a wall or on a stand. They carry a registration number or a message but are not intended for the road.
What are show number plates used for?
Show number plates often feature on a display stand, in a showroom, in a gift or on a car at an event while it is parked. The key point is that the vehicle is not driven on the road with them in place of the legal plates.
Do show plates have to meet the British Standard?
Not for display. A road plate must meet the British Standard (BS AU 145e), but a plate made purely to display need not follow the legal font or spacing, since it is not meant for road use.
Are Show Plates Legal In The UK?
Owning, making and displaying show plates UK collectors use is generally fine, provided they are really for display and are not used to mislead anyone. They are not a lawful substitute for road plates.
Can you drive with show plates?
No. Using a display-only plate on a public road in place of the proper plates can lead to penalties, and you should check the official guidance on GOV.UK.
Why does the line matter?
The law needs every road plate to be identifiable by cameras and by people, so a plate that fails the standard defeats the purpose.
What Is The Rule For GB Show Plates?
GB show plates are the same idea with the country identifier on the left. A national flag with GB or UK, or the country name, is an allowed extra on a legal road plate if the rules are met, and show plates can copy the look.
Does the flag change legality?
Only on a road plate: the flag and identifier must follow the rules. On a pure display piece, there is no road-legal test.
Can A Plate Be Shown At An Event But Not Driven?
Yes, many owners use a car show plates setup only while a vehicle is parked and on display, then refit the legal plates before the car moves.
- Keep the legal plates with the vehicle.
- Swap before the car goes on a public road.
- Do not leave a display plate on a car that is driven.
- Make sure the show plate does not copy someone else's registration.
What about photographs?
A show plate in a photo is normally fine, but the finished shot should not be used to pass off a false registration.
Can You Show A Number Plate On A Car On The Road?
If you want to show number plate on car that is driven, the plate must be the legal type. Anything else risks a fine, and the exact outcome depends on the offence.
Is a novelty plate a show plate?
A novelty plate is made for fun but is not legal on the road. See funny number plates for what is allowed.
What Is The Difference Between A Display Plate And A Road Plate?
| Item | What it is | Legal on the road? | Typical use |
|---|---|---|---|
| Preview image | A mock-up on a picture | Not a plate at all | Choosing a number |
| Show plate | Display-only plate | No | Events, photos, gifts |
| Road plate | Made to BS AU 145e | Yes, if fitted correctly | Everyday driving |
| Novelty plate | Non-standard styling | No | Fun, display |
| Retained number | Number held on a certificate | Not displayed until assigned | Waiting for a vehicle |
How should you read the table?
Only the road plate row is a legal plate. Everything else is a picture or a keepsake.
What Does A Legal Road Plate Need?
A legal plate must be reflective, follow the legal font, use correct spacing and carry the supplier's name and postcode. See legal number plates in the UK for the full set of requirements.
- The front plate is white and the rear plate is yellow.
- Characters are black.
- The typeface is a version of Charles Wright 2001.
- Only a registered number plate supplier may make the plate.
Why does the font matter?
The car registration plate font gives every character a fixed shape so cameras can read it. See car registration plate font for what the font looks like.
What about spacing?
The gap between characters and groups is regulated. Read about number plate spacing before choosing a layout.
Can You Preview A 3D Or Gel Plate?
You can, but a picture of raised characters says nothing about legality. A 3D or 4D plate is legal only if it still meets the standard. See 3D reg plates for the details.
What about metal plates?
Metal plates are not automatically illegal, but they must meet the same standard. See metal number plates for what is allowed.
Why Are Flip Plates And Stickers Not A Viewer?
A flipper is a plate that changes to show different characters. It is designed to hide or change the registration, and it is illegal. The number plate flipper explains why.
Are stickers allowed to alter characters?
No. Stickers or paint used to change characters are not allowed on a road plate. See number plate number stickers.
How Do You Turn A Preview Into A Real Plate?
Moving from preview to plate is a sequence of steps and a registered supplier does the making.
- Decide the registration and check you are entitled to use it.
- Gather proof of identity and proof of entitlement.
- Order from a registered number plate supplier.
- Receive plates made to BS AU 145e with the supplier's details.
- Fit them to the correct vehicle.
Can you make your own plate?
Only a registered supplier may make plates for the road. Read can you make your own number plate for the rules.
How Do You Put A Private Plate On A Car?
You assign the number through the DVLA, and the vehicle must meet its conditions. How to put a private number plate on a car covers the steps.
What if the number is already on another car?
You normally need to retain it first. See how to retain a number plate.
What Is A Retained Number And A Private Plate?
A private plate is a registration assigned to a vehicle, and a retained one is held on a certificate until it is assigned.
What does the V778 do?
A V778 retention document records a number taken off a vehicle and kept. A V750 shows a number bought from the DVLA that is waiting to be assigned. The V317 form route is one way to apply, with online routes on GOV.UK.
What Should You Look For In A Good Preview Tool?
Not every viewer is equal, and a few features separate a useful one from a toy.
- It lets you choose the vehicle shape and colour.
- It shows both the white front and the yellow rear plate.
- It uses a typeface close to the legal one.
- It makes clear that the picture is not a legal check.
- It does not ask for more personal data than it needs.
Does it matter who runs the tool?
A tool run by a plate seller will usually push its own stock. That is not wrong, but compare it with the DVLA's own listings.
Can a preview show spacing faults?
Only if it copies the legal spacing. Many free-style tools do not, so a plate that looks neat on screen might still fail the rules once measured.
How Do You Preview A Name Or Word As A Registration?
Many keepers try to read a word into letters and numbers. A preview shows whether the number plate reads as a word or is easily confused.
Which characters are easy to confuse?
O and 0, I and 1, S and 5, and B and 8 are classic pairs. A viewer helps you judge them, but the legal spacing and font are what really keep them readable.
Is it acceptable to space a plate to look like a word?
Altering spacing so characters look different is not allowed. The legal gap is fixed, and the number plate spacing rules explain what counts as illegal.
Do Show Plates Matter To Collectors?
Yes. Collectors of memorabilia often display old plates as show reg plates, and these may be genuine retired road plates or purpose-made replicas.
- Retired plates are typically kept as memorabilia.
- Replica plates are made for display.
- Neither should be refitted to a road vehicle unless they meet today's standard.
- A plate bearing a real, current registration must not be used to mislead.
What about vintage-style plates?
Older plates may be legal on certain classic vehicles only if they meet the rules for that vehicle. See vintage vehicle number plates.
What about antique registrations?
An antique registration is a number, not a plate. See antique number plates for the difference.
How Do You Check A Vehicle That Already Has A Plate?
When you see a plate on a car and want facts, use the registration with a vehicle lookup rather than a preview.
- Note the registration exactly as it appears.
- Enter it into the free number plate check.
- Compare make, colour and fuel with the car in front of you.
- Look at MOT and tax status.
- Ask for a full history check before a purchase.
What if the details do not match?
A mismatch between the plate and the record can point to a cloned or wrong plate, so be cautious and do not buy until it is explained.
What About Plates On Trailers And Caravans?
Trailers follow their own rules, and their plates show the registration of the towing vehicle, with separate plates for some trailers. See number plates for trailers.
Can a viewer preview a trailer plate?
Few do, and the rules differ from a car's, so use the official guidance.
Do Motorbikes Need Previews Too?
Motorcycles carry a rear plate only, and a viewer for a bike plate is rarer. Read motorbike number plates for what applies.
Why is a bike plate different?
Space is smaller, and the legal plate size follows the vehicle type, so always confirm with GOV.UK.
What About Northern Ireland And Ireland?
Northern Ireland uses a different plate format from Great Britain, so a GB preview tool may not suit it. Registration and tax stay with the DVLA, while testing is run by the DVA.
Is an Irish plate a GB plate?
No. The Republic of Ireland uses a different system, and its records are not on DVLA systems. See Irish number plates.
What If The Tool Shows A Number As Available?
Treat it as a lead and confirm with the seller or the DVLA.
- Check the number is not already assigned.
- Confirm the price and fees directly with the seller.
- Ask what documents come with it.
- Make sure you are entitled to use it on your vehicle.
Where do plates for sale come from?
They come from the DVLA, from dealers and brokers and from private sellers. See sell my licence plate.
How Do You Pick A Number Worth Previewing?
Value comes from length, readability, rarity and demand. A cherished number plate with a short or word-like combination often attracts the most interest.
What about dateless combinations?
A dateless plate has no age identifier, so a preview of one cannot reveal a car's age. See cherished plates for how they work.
Where can you find ideas?
The number plate idea generator is a starting point for combinations to preview.
How Big Is The Plate You Are Previewing?
Plate sizes vary by vehicle and by character spacing, and the viewer rarely shows the exact space. The UK number plate size rules cover the dimensions in general terms.
What about the rear plate?
Check the rear colour and position. The rear number plate rules explain the yellow background and the display requirements.
How Can You Tell Whether A Plate Is Worth Buying?
A preview cannot value a number. For a view on worth, see value my number plate and DVLA number plate auctions.
What Documents Help When You Are Ready To Display?
Keep every document that shows your entitlement and the vehicle's identity.
- The V5C for the vehicle.
- The V750 or V778 for a bought or retained number.
- Proof of identity for the supplier.
- Receipts for any plate you order.
What Should You Check Before A Number Goes On A Car?
A number must not make a car look newer than it is, and some combinations are not issued. The conditions are on GOV.UK.
How do you read the plate once it is on?
See how to read a UK number plate for how the memory tag and age identifier work.
What About Removing A Plate You No Longer Want?
If you want to take a private plate off, see how to remove a private plate. The vehicle usually returns to its original number or a replacement as the DVLA directs.
How Are Plates Actually Made?
A registered supplier uses a press or printing process to make plates to the standard. See the number plate machine explanation for how it works.
What Are Common Mistakes With Previews And Show Plates?
Most problems come from treating a mock-up as legal advice.
- Assuming a preview means the number is available.
- Fitting a show plate for the drive home.
- Ignoring the legal font and spacing.
- Buying a number that makes the car look newer.
- Forgetting the plate must match the vehicle.
- Ordering from a seller that is not a registered supplier.
- Treating a photo mock-up as proof of entitlement.
- Leaving a display plate on a car that is then driven.
- Skipping the V5C check when the plate looks right.
Myths About Show Plates
- Myth: a show plate is fine for a short drive. It is not a legal road plate.
- Myth: a preview proves legality. It does not.
- Myth: any fancy plate is legal if it is clean. It must meet the standard.
Where Is The Official Source?
The DVLA and GOV.UK are the final word on registration, plate rules and display. Check there before spending money or fitting anything.
Frequently Asked Questions
What is a plate viewer?
A plate viewer is an online preview tool that shows a registration on a picture of a car so you can judge how it looks. It is usually provided by a plate seller or broker, is not an official DVLA service and does not confirm that the number is available or that the plate would be legal to display.
What is a number plate visualiser?
A number plate visualiser is another name for a preview tool. It places your chosen characters on a plate shape or car image so you can compare options. It gives an impression only, so check the finished plate against the legal font, spacing and colour rules before ordering.
How will a number plate look on my car?
Use a preview tool, pick a vehicle that resembles yours and compare the front and rear plates. The picture is approximate, so also consider the space on your bumper, how the characters read at a distance and whether any letters could be misread. A registered supplier can advise on layout.
What are show plates?
Show plates are display-only plates used at events, in photographs or as keepsakes. They are not intended for the road, and they need not meet the British Standard because they are not used to identify a vehicle on public roads. The proper road plates stay with the vehicle.
Are show plates legal in the UK?
Making and displaying show plates is generally allowed if they are really for display and not used to mislead. They are not a lawful substitute for road plates, so using one on a public road in place of the proper plates could lead to a penalty. Check GOV.UK for current guidance.
Can I drive with show number plates fitted?
No. A road vehicle needs legal front and rear plates, where the vehicle type requires them, made to the British Standard by a registered supplier. Display-only plates should be removed and the legal plates refitted before the vehicle is driven on a public road.
What is a GB show plate?
A GB show plate copies the look of a road plate with a GB identifier, sometimes with a flag, but is made for display. On a legal road plate the flag and identifier must follow the rules, and the plate must meet the standard, so a GB show plate should not be used as one.
Can I view a registration plate on a car before I buy it?
Yes, many sellers offer a viewer that shows the registration on a car image. It helps you judge readability but does not confirm availability, price or entitlement. Availability depends on the DVLA or the seller, and you must meet the conditions to put the number on your vehicle.
Is a preview the same as a number plate check?
No. A preview mocks up how letters might look, whereas a number plate check looks up the record of a real vehicle, such as make, model, colour, fuel, MOT and tax status. A check does not show insurance, finance or owner details.
Are 3D or gel plates legal if the preview looks fine?
Only if the finished plate meets the same standard as any other: legal font, spacing, colours and reflectivity. A preview image cannot tell you that, so confirm with a registered supplier and check GOV.UK before fitting raised or gel characters.
Who can make number plates for the road?
Only a registered number plate supplier may make plates for road use. The supplier must see proof of your identity and entitlement to the registration number, and the plate must carry the supplier's name and postcode together with the British Standard reference.
Can a plate make my car look newer than it is?
No. The DVLA does not allow a registration that suggests a vehicle is newer than it is, and some combinations are not issued at all. Check the current conditions for assigning a private number on GOV.UK before buying one.
Does a plate viewer work for older plate formats?
Usually yes, because a mock-up only places characters on a plate shape. It may show a dateless number, a prefix plate (year letter first), a suffix plate (year letter last) or a current style plate (two letters, two digits, three letters). The preview does not check whether the number can be assigned to your vehicle, so confirm that with the DVLA on GOV.UK.
