Buyer's Guide · Reading time: about 10 minutes
A vehicle identity check confirms that the car in front of you is the car described in the records. You compare the license plate, the VIN (the chassis number), the registration documents and the physical vehicle, and you look for any mismatch. In the Netherlands, the RDW registration data gives you the starting point. Then you confirm it on the car itself and add history sources for what the register doesn't hold.
TL;DR
- A vehicle identity check links four things: the license plate, the VIN, the registration papers and the physical car. All four must describe the same vehicle.
- The RDW check starts from the registration number. It does not prove that the number stamped on the car is genuine, so you must compare the VIN on the car yourself.
- A clean result is not a guarantee. Recall data, foreign history and unreported damage can all be missing from a record.
- Cloned and rebadged vehicles are the main reason to check identity at all. They are rare, but they are expensive when you meet one.
- Use free checks first, add a history report if the car is serious, and finish with an independent inspection before you pay.

What a vehicle identity check actually is
Every road vehicle has an identity made of a few linked elements: the registration number on the plates, the VIN stamped into the chassis, and the registration papers that tie the two together. An identity check asks one question: do all of these point to the same vehicle, and is that vehicle what the seller says it is?
People use several names for the same thing: vehicle identification check, VIN check, chassis number check, plate check. They overlap, but they are not identical:
- A plate check starts from the registration number and pulls data from the register.
- A VIN check starts from the chassis number and is used to verify that the physical car matches the data.
- A history check builds on both and adds events over time: mileage readings, ownership types, inspections, damage, theft reports.
In practice you need all three. The plate check is quick and free. The VIN comparison happens on the car, in person. The history check fills in what neither can show.
What the VIN is and where to find it
The VIN is a long alphanumeric code that identifies one individual vehicle. It works like a serial number: no two vehicles should share one. It is stamped or engraved on the vehicle and printed in its documents.
RDW's buying advice is explicit about the comparison you should make: check that the VIN matches the number stamped on the vehicle, and compare the printout of the registration check with the vehicle and its registration certificate (RDW, tips for buying a vehicle). That single step is the heart of an identity check.
Where you typically look:
- The registration documents. The VIN is printed on the registration certificate. Take a photo of it during the viewing.
- The vehicle itself. The number is stamped on the body or chassis. Many cars also show it on a plate in the engine bay or at the base of the windscreen, visible from outside. Where exactly depends on make and model, so look up your model before the viewing.
- The seller's advert or invoices. Service invoices often list the VIN. If the number on old invoices differs from the one on the car, ask why.
Do this in daylight, with the seller present, and write the VIN down yourself rather than reading it from a message the seller sent you. Check every character: a single swapped digit is the kind of mismatch that matters.
What the Dutch registration check covers
The RDW registration check starts from the registration number. According to RDW, it provides some data for all Dutch vehicles registered with the RDW, along with historical vehicle data, transferability and known recalls (RDW). RDW keeps separate registers for vehicle registration, recalls and related information, and its public services include the registration check, the vehicle report, the mileage check and the recall lookup (RDW, your vehicle and your data).
The RDW vehicle report can show mileage readings, technical data, APK (periodic inspection) information and vehicle history, including an overview of the types of owners. Fuel, emissions and emissions class give you environmental information (RDW, explanation of the vehicle report). If you own or hold the vehicle yourself, RDW lets you request its report free of charge online (RDW, request a vehicle report).
For a closer look at what is free and what is not, see our guide to the RDW license plate check. If the RDW's data format looks confusing, how to read the Dutch vehicle information system walks through it field by field.
What you can verify from the register
| Question | Where the answer comes from | What it tells you |
|---|---|---|
| Does the make, model and fuel type match the advert? | Registration check | Whether the seller describes the car correctly |
| Is the VIN the same as on the car and the papers? | Registration check plus your own inspection | Whether the identity is consistent |
| Has the mileage been plausible over time? | Mileage check and vehicle report | Whether the odometer reading fits the record |
| Is the APK valid and what was its history? | Vehicle report | Inspection status and past results |
| Can the car be transferred? | Registration check | Whether the sale can legally go through |
| Is there a known recall? | Recall lookup | Open manufacturer campaigns reported to RDW |
| Is it reported stolen? | Theft-status sources | Whether the vehicle is on a theft register |
A check like this takes a few minutes and is best done before you even go to see the car. ANWB's used-car guidance also advises doing an RDW check before the viewing (ANWB, what to look for when buying a car).
Why identity matters: cloning and rebadging
Most sellers are honest, and most mismatches are paperwork errors. But two forms of identity fraud are the reason the check exists.
Cloning. A stolen vehicle takes on the identity of a similar vehicle that is legitimately registered and still in use. The thief copies the number plates and the VIN details of that genuine car. On paper, everything looks right, because it is the details of a real, clean vehicle.
Rebadging (identity swapping). The identity of a damaged or written-off vehicle is reused on another car, so a wreck effectively gets a clean history.
RDW warns about both, and notes the uncomfortable consequence: in such cases the registration-number check can point to the correct identity while not exposing the physical fraud (RDW). In other words, a database lookup alone cannot catch a cloned car. The lookup tells you what the plate belongs to. Only the comparison against the actual vehicle tells you whether this car is that vehicle.
That is why a good identity check has two halves:
- Data side: register data, mileage history, theft status.
- Physical side: the VIN on the car, the registration certificate, the plates, the car's specification compared to the record.
Warning signs worth a second look
- The VIN on the car is scratched, painted over, re-stamped or on a plate that looks tampered with.
- The make, colour, engine or fuel type on the register differs from the car in front of you.
- The seller will not meet at their home address or will not show an ID.
- The price is far below comparable cars, with a story that explains why.
- The seller pushes for cash, speed or a handover somewhere neutral.
None of these proves fraud alone. Several together are a reason to walk away.
What a check can miss
An honest guide to identity checks has to say what they cannot see. Treat a clean result as a good sign, not as proof.
Recalls may be incomplete. RDW reported on 11 August 2026 that manufacturers are currently not legally required to provide the RDW with recall information and the lists of affected VINs, so the registration may not be complete (RDW news). A clean RDW result therefore cannot be treated as proof that no manufacturer campaign exists. RDW also says a published recall disappears from the check once the manufacturer or importer reports completion, and that an open recall is currently not in itself a reason to fail the APK. Even so, it says owners should arrange the free manufacturer repair without waiting for routine maintenance (RDW, recalls).
Damage history is only as good as its sources. ANWB points out that a missing damage record does not prove that a car was never damaged: history services contain only the damage reported to their contributing sources, and the result is an aid, not a guarantee (ANWB, check a car's damage history). Its advice is to rely on more than one independent source rather than a single clean report.
Imported cars have gaps. ANWB notes that imported vehicles may have incomplete foreign damage histories, and that RDW permanently shows "no judgment" for the mileage of imported cars. Buyers should therefore inspect maintenance stamps and mileage records (ANWB, buying an imported car). If you are looking at an import, ANWB also recommends checking the RDW import indication, the BPM depreciation method and the assessment date, asking for the tax valuation report, and writing no-damage and mileage guarantees into the purchase contract.
A database cannot see the car. Rust, worn brakes, a tired battery and a poorly repaired crash do not appear in any register. For that you need eyes and tools. Our guide on checking engine, brakes, battery and tyres with a mechanic and a plate check shows how the two fit together.
Step by step: how to run an identity check before you buy
- Check the plate before you travel. Enter the registration number and compare make, model, colour, fuel and first registration with the advert. Anything off is a question for the seller before you spend an afternoon on it.
- Check the history. Look at mileage over time, APK history, number of owner changes and recall status. Write down anything odd.
- Check theft status. A theft flag is an immediate stop. Our guide on how to check if a used car is stolen explains what the sources are and how to read them.
- Arrange the viewing safely. RDW advises arranging a private sale at the seller's home, checking the seller's passport or driving licence, transferring the vehicle together at a registration counter and paying by bank transfer rather than cash (RDW).
- Compare the VIN. On the car, in the documents and in the register printout. Check that the right registration certificate and number plates are present.
- Ask direct questions. Previous owners, accidents, repairs, why the seller is selling, where the service invoices are.
- Inspect and test drive. ANWB says a test drive gives a reasonable impression but cannot reveal everything (ANWB, how to take a good test drive).
- Consider an independent inspection. An occasion inspection by an independent specialist can add the certainty that you can't get by yourself. See what a pre-purchase inspection costs and what to do with the report.

What to do when something does not match
The right reaction depends on the mismatch. Stay calm and work through it in order.
The VIN on the car differs from the papers. Do not buy, and do not pay a deposit. Ask the seller for an explanation in writing. A typing error on an old invoice is one thing. A different number on the car itself is another.
The register shows a different car than the one you see. Different colour, engine or model may be a legitimate modification that was never registered, or it may be a sign that the plates belong to another car. Ask for documents. If the answers are vague, walk away.
The mileage looks wrong. Compare the reading on the dash with the readings in the mileage history and with service invoices. A gap or a drop is a question the seller has to answer with documents. For imports, remember that Dutch records may not show a judgment, so documents carry more weight.
A theft flag appears. Stop. Do not continue the transaction, and contact the police. Do not confront the seller alone.
An open recall shows up. This is usually manageable: the manufacturer repair is free for the owner, and you can ask the seller to have it done or arrange it yourself after purchase. Because recall data may be incomplete, ask the dealer network of the make about the VIN as well.
Everything matches, but your gut says no. Walk away anyway. There are plenty of other cars.
Our perspective
We built CarTrace around a simple observation: the information a buyer needs exists, but it sits in separate places. Registers, inspection databases and theft records each hold a part of the picture, and few people have the time to piece them together before a viewing.
That is why we bring Dutch and European sources into one place and start with a free plate check. Our aim is that the first look at a car should cost you nothing, and should already tell you whether the car deserves a viewing. Our assistant Leo is designed to point out the details that matter in a given result, such as a mileage pattern or a status change, so you don't need to be a specialist to read the record.
We also say plainly that a report supports your decision and does not replace the physical inspection. Used together, a clear data check and a careful look at the car give you the best chance of avoiding a blind surprise.

A short note for sellers, owners and businesses
Identity checks are not only for buyers.
- Sellers benefit from showing a clean check. A matching VIN, a clear mileage history and a valid APK remove the questions that slow down a sale. If you own the car, you can request your own RDW vehicle report free of charge and share it with serious buyers.
- Owners can watch their vehicle over time for status changes such as new events on the record or a recall. It is also worth knowing what the register says about your car, because errors are easier to fix early.
- Dealers and leasing companies need identity verification at volume. They check VIN, registration and history before they take a car into stock or into a lease portfolio, and they keep the evidence on file.
FAQ
What does a VIN check show?
A VIN check compares the chassis number with the registration data and, depending on the source, adds history such as mileage readings, APK information and owner types. In the Netherlands, the RDW vehicle report covers mileage readings, technical data, APK information and history. It does not show everything, so combine it with a look at the car and the papers.
Is a VIN check the same as a license plate check?
Not quite. A plate check starts from the registration number and reads the register. A VIN check focuses on the chassis number, and you must compare it with the number on the car. In Dutch practice, you do both: the plate check tells you what the plate belongs to, and the VIN comparison tells you whether the car in front of you is that vehicle.
Can a VIN check detect a cloned car?
Not by itself. RDW warns that, with cloned or rebadged vehicles, a registration-number check can point to the correct identity without exposing the physical fraud. You need to compare the VIN on the car with the documents, ask for the history in writing and be wary of an unusually low price. A theft-status check and an independent inspection add further protection.
If the report is clean, is the car safe to buy?
It is a good sign, not a guarantee. History data only contain what was reported to the sources, so unreported damage may not appear, and recall data may be incomplete. Ask ANWB-style questions of the seller, read the maintenance invoices and consider an independent purchase inspection before you pay.
Do I have to pay for a vehicle identity check?
The basic plate check is free with CarTrace and with RDW's public services. Fuller reports and ongoing monitoring are part of paid plans, although the complete car report is currently free during our launch. Check the pricing page for the current terms.
