You can find the VIN on the title document. It will appear in different places, depending on your state, but should be on the front of the title near the top. The VIN should also appear on the front of your registration card. Contact your Department of Motor Vehicles if you don't have a registration card for the car. The VIN should also appear in the owner's manual that came with the car. If the car is new, you should have the manual. However, you might not have it if you bought a used car. You probably had to provide the VIN to your insurer, so check your insurance card or insurance policy. The VIN should be listed there.

Check the title. Find your registration card. Read the owner's manual. Check your insurance documents.
