A VIN is a Vehicle Identification Number and can be found in a couple of places including on the car's registration label, on the build plaque in the engine bay or on the passenger side windshield and door jamb. It also appears on registration and insurance documents. You’ll need to supply your VIN or registration number when selling your car.
Remember, a VIN will never contain the letters 'i' 'o' or 'q'.
