Contact the Department of Motor Vehicles of your state. Furnish the VIN number of the vehicle and request a title record from the department. If the vehicle has a license plate from another state, contact the Department of Motor Vehicles of the state and request a title record.
Can I trace the owner of a car registration number?
Look for the official website of the government agency that issued the license plate. If you can't find the information online, you can always call a motor vehicles agency office and ask. Explain that you want to find a vehicle's registered owner and the only information you have is a license plate number.
