Start with the registration, then look at the car
When you have found a used car you like, a sensible vehicle check begins with the registration number. That gives you a starting point to compare the advertised details, the official records and the actual car. This guide explains how to check identity and paperwork, what online records can and cannot cover, and what to do next before you pay. To begin, enter the registration at our vehicle check registration page.
Why registration comes first
The registration is the reference used by official services such as the DVLA vehicle enquiry and the MOT history service. Confirm the make, model, colour, fuel type and engine size match the advert. If anything differs, ask why before travelling to view the car.
Compare identity, VIN and paperwork with the car
A registration match is only the start. Do this at the viewing, with the seller present.
Check the VIN
The vehicle identification number is stamped or displayed on the car, often visible through the windscreen at the base of the dashboard and stamped in the engine bay or door frame. Record it and compare it with the VIN on the V5C and any MOT or service documents. The VIN should be consistent across all of them and should not look tampered with.
Read the V5C against the car
The V5C records the registered keeper, not legal title or proof of ownership. Check that the registration, make, model and VIN match, and look for signs of unusual history. If the document looks altered, or the seller cannot explain a recent keeper change, pause and ask questions.
Inspect the vehicle itself
Walk around the car, check panel gaps and paint for signs of repair, and take a test drive. For anything you are serious about, consider an independent mechanic’s inspection. Neither an online check nor a document can confirm the car drives safely.
Official records versus commercial report coverage
It helps to know where the information comes from.
- Official public records include DVLA vehicle details, tax status and MOT history. These are free to view and reliable within their limits, but they do not cover everything about a used car.
- Commercial history reports may draw on other databases, such as finance or insurance write-off markers. Coverage varies by provider and by vehicle, so compare what each report states it includes.
Neither type of record proves mechanical condition, and databases can lag behind real-world events. Always treat a report as evidence to be weighed, not a guarantee.
Know the limits, then plan next checks
Online checks cannot tell you whether the car is sound, nor are they proof that every issue has been recorded. Before agreeing a sale:
- Confirm the VIN, registration and V5C match the car.
- Read the MOT history for advisories and mileage patterns using our MOT guide.
- Ask about outstanding finance using our finance check guide.
- Ask about write-offs and repairs using our write-off check guide.
- Take a careful test drive and, if serious, arrange an inspection.

FAQ
Can a vehicle check confirm the car is mechanically sound?
No. Online records do not replace a physical inspection, test drive or independent mechanic’s report.
What if the VIN or V5C does not match the car?
Pause the purchase. Ask the seller for an explanation and supporting evidence before paying. Inconsistent identity is a serious reason to walk away.
Is a commercial report more complete than official records?
It can include additional data, but coverage varies and it is not a guarantee. Compare what the report states, and confirm key facts against official sources and the car itself.
