What is a VIN number?

Vehicle identification number, commonly known as VIN or chassis number, is a unique numerical ID assigned to your car to legally identify it, and help differentiate it from other cars of the same make and model.
The VIN is usually 17 digits long and it can’t be changed. Among other uses, this helps identify your car if it’s stolen.

Where is the VIN on the car?

The VIN is stamped into the chassis of your car (hence why it’s also known as ‘chassis number’). Some cars also have the VIN on the windshield, side of the dashboard, or the door jamb. You should check your car’s owner manual to find out where the VIN is located.
You can also find the VIN on the car’s logbook – this helps spot a stolen car if the VIN doesn’t match on the logbook and the car’s chassis when you’re looking to buy a used car.

When can I get a new VIN?

If you have a kit car - i.e. a car that you've assembled together from car parts - or if you’ve restored or radically altered a car, you may have to contact the DVLA to register the new vehicle.
Once the DVLA know about your new car, you get an authorisation letter so that the car can be assigned a new VIN. The new VIN helps you register the car so that you can legally drive it on the UK roads. If you want to assign the original number plates to the car, you will need to prove the car’s original VIN to the DVLA or apply for a replacement identity number using the V765 form.
