Locate a Department of Motor Vehicles office in your area. Search your local yellow pages to find the one nearest you.
Bring your license plate, registration card and decals to the DMV office to surrender them to the DMV clerk. Decals are stickers that you receive when you register your vehicle with DMV. These stickers are placed on your license plate and need to be renewed every year.
Fill out the appropriate forms. Let the clerk know you also want to cancel your car registration.
Mail your license plate, decal and a signed letter requesting cancellation to the DMV. Contact your local DMV office to get the address of its central services division. Send your items by a traceable delivery method with a delivery confirmation. Once your request is processed, the DMV will send a letter confirming the cancellation. Keep this letter for your records.
