What Is a V5C and Why Does It Matter When Buying a Car?
The V5C is the official vehicle registration document for every car registered in the UK. It is commonly called the logbook. Most people have heard of it, but fewer know exactly what it contains, what it proves, and where it falls short.
If you are buying a used car, understanding the V5C is essential.
What is a V5C?
The V5C is issued by the DVLA and contains the official registration details for a vehicle. It covers:
- The registered keeper's name and address
- The vehicle's make, model, colour, and body type
- The engine size and fuel type
- The Vehicle Identification Number (VIN)
- The date of first registration
- The number of previous registered keepers
It is printed on distinctive green paper with a watermark and a unique document reference number.
This is the most commonly misunderstood thing about the V5C. It is a registration document, not a title deed. A finance company may legally own a car while the person making the payments is listed as the registered keeper on the V5C. Being handed a V5C does not automatically mean the seller has the legal right to sell.
Why does it matter when buying a used car?
The V5C is the primary way to verify that the car in front of you is what the seller claims it is.
The registered keeper's name and address should match the person selling the car, at the address where you are viewing it. If the V5C shows a different name or a different address, ask for a clear explanation before proceeding.
The VIN on the V5C should match the VIN stamped on the dashboard, door frame, and chassis of the car. A mismatch is one of the clearest signs of a cloned or stolen vehicle. Always check this in person.
Make, model, colour, engine size, and year on the V5C should all match the car in front of you exactly. Any discrepancy needs explaining. A resprayed car with a different colour from the V5C should have been updated with the DVLA.
The number of previous keepers is shown on the V5C. One or two keepers for a five-year-old car is typical. Many keepers in a short period can indicate the car has had problems that have caused owners to move it on quickly. It is not a definitive red flag on its own, but it is worth factoring in.
What the V5C does not tell you
A car can have a completely clean V5C and still have thousands of pounds of outstanding finance against it. The finance company's interest does not appear on the V5C. You need a separate history check (HPI, RAC, AA, or a free checker like Motoreasy) to confirm whether finance is recorded.
A cloned car will have a V5C that appears entirely legitimate, because it was copied from a real, clean vehicle. The V5C alone cannot tell you whether the car in front of you is stolen. Always verify the VIN physically and run a paid history check that includes a stolen vehicle search.
A car that has been written off and repaired will not show that on the V5C. Write-off status is held on insurance databases and requires a history check to uncover.
How to check a V5C is genuine
Hold the V5C up to light. A genuine document has a watermark visible through the paper. The paper itself has a distinctive feel. Forged V5Cs are sometimes printed on regular paper and lack this watermark.
The document reference number in the top right corner can be verified against DVLA records using the free vehicle enquiry at gov.uk/get-vehicle-information-from-dvla. If the number does not match the registration, the document is forged.
What to do with the V5C when you buy
When a car changes hands, both buyer and seller have responsibilities:
- The seller tears off the yellow V5C/2 (new keeper supplement) and gives it to the buyer as a temporary record
- The seller notifies the DVLA of the sale, either by posting the green V5C section or using the online service at gov.uk
- The buyer receives a new V5C in their name within 6 weeks
- The buyer can also update the registered keeper online immediately at gov.uk/change-name-address-v5c
Keep the yellow slip safe until your new V5C arrives. It is your only proof of keeper status in the meantime.
Check the MOT history alongside the V5C
The V5C confirms the car's registered identity. The MOT history confirms whether the car behind that identity has been consistently maintained, tested, and driven the miles it claims.
The Don't Buy A Lemon Chrome extension shows the full MOT history automatically on every listing you browse, across AutoTrader, Facebook Marketplace, eBay Motors, Gumtree and more.
Frequently asked questions
Is the V5C proof of ownership? No. The V5C shows who the registered keeper is. Ownership is a separate legal concept. A finance company can own a car while someone else is the registered keeper.
What if the seller does not have a V5C? A missing V5C is a red flag. The seller should be able to explain why it is not present. You can buy a car without one, but you cannot verify the car's registered details and you will need to apply for a duplicate from the DVLA for £25. Factor the risk into your decision.
Can you change a car's colour on the V5C? Yes. If a car has been resprayed, the registered keeper must notify the DVLA and update the V5C to reflect the new colour. A colour discrepancy between the car and the V5C that the seller cannot explain is a warning sign.
How long does it take to get a new V5C after buying a car? Usually within 6 weeks. The yellow new keeper supplement acts as your proof of keeper status in the meantime. If a V5C does not arrive within 6 weeks, contact the DVLA.
