Vehicle identification number

All vehicles registered in the UK must have a unique, stamped-in vehicle identification number (VIN) and registration number.

Find your VIN

The VIN is usually stamped into the chassis of the vehicle. It may be lost if you rebuild or modify your vehicle.

When you may need a new VIN or registration

If you have a kit car, rebuild, or radically altered vehicle, DVLA will usually have to assess it.

You may be able to keep its original registration number if you can prove the vehicle’s original VIN. If you can’t, you’ll have to apply for a replacement identity number.

DVLA will give you an authorisation letter to get the vehicle stamped with the new VIN if your vehicle passes its assessment.

You then need to register the vehicle - you can only do this when DVLA receives confirmation it’s been stamped with the correct VIN.

  1. Step 1 Check the vehicle before you buy it

    You'll need the vehicle's registration number, make, model and MOT test number. You also need to see the V5C vehicle registration certificate (log book).

    1. Check the details you've been given match DVLA's information
    2. Check the vehicle's MOT history
    3. Check if the vehicle has been recalled because of a safety issue
    4. Check the log book isn't for a stolen vehicle
  2. Step 2 Buy and register the vehicle

    Once you've bought the vehicle, you have to register it. How you register it depends on whether it has a V5C registration certificate (log book).

    1. Find out how to register your vehicle
    2. Get a vehicle log book if you don't have it £25
  3. Step 3 Insure the vehicle

    You must have insurance before you can use your vehicle on the road.

    1. Check if your vehicle is insured on the Motor Insurance Database
    2. Read about vehicle insurance
  4. Step 4 Tax the vehicle
