How to check a V5C logbook
The V5C is the registration certificate, and checking it properly is one of the simplest ways to avoid a stolen or cloned car. It does not prove who owns the car, but a V5C that does not match the car, or the seller, is the clearest warning sign there is.

Check it is genuine
Hold it up to the light: a genuine V5C has a "DVL" watermark. Be wary of any document that looks photocopied, has been altered, or that the seller is reluctant to let you handle.
The DVLA has warned about batches of blank logbooks that were stolen. Do not buy a car whose V5C has a serial number between BG8229501 and BG9999030, or between BI2305501 and BI2800000, and report it to the police.
Check it matches the car
Compare the Vehicle Identification Number (VIN) on the V5C with the VIN on the car, usually visible through the bottom of the windscreen and stamped on the body, often under the bonnet or on a door pillar. Check the registration, make, model, colour and engine size match too.
A mismatch on any of these is a reason to walk away. Cloned cars carry the identity of a legitimate car of the same make and model, and the VIN is the detail cloners most often get wrong.
Check it matches the seller
The V5C shows the registered keeper and their address. Buy from that person, at that address. A seller who wants to meet in a car park or service station, or whose name and address do not match the document, may not have the right to sell the car.
The registered keeper is not necessarily the legal owner (a car on finance belongs to the finance company until it is paid off), which is why a logbook check goes hand in hand with a finance check.
What the logbook cannot tell you
A V5C will not show outstanding finance, insurance write-offs or whether the car has been reported stolen. Those are on separate databases. An Odomint Check covers them, alongside the free MOT history and mileage record.
If the seller has no V5C
Walk away, or at least pause. Sellers sometimes say the logbook is "in the post" or "with the DVLA". A genuine seller can apply for a replacement V5C before selling, and should. Buying without one means you have no new keeper slip to tax the car with, and no documentary link between the person taking your money and the car.
If you do go ahead, make sure the seller notifies the DVLA of the sale online in front of you, and get a written receipt with their name, address, the registration, the VIN, the price and the date. That paper trail matters if anything about the car later turns out to be wrong.
Common questions
Does the V5C prove ownership?
No. It shows the registered keeper, who is not always the legal owner: a car on finance is owned by the finance company until it is paid off.
Which V5C serial numbers are stolen?
The DVLA has warned against V5Cs with serial numbers BG8229501 to BG9999030 and BI2305501 to BI2800000, from batches of stolen blank logbooks.
Where is the VIN on a car?
Usually visible at the base of the windscreen, and stamped on the body, often under the bonnet or on a door pillar.
