You are not limited to going to the Department of Motor Vehicles for a VIN verification. There are more convenient alternatives that can make it easier for you to satisfy the DMV's requirements for registering your vehicle.
A vehicle verifier follows the REG31 form from top to bottom, documenting the vehicle year, make and model, VIN and its location, number of wheels, number of axles, license plate, fuel type, US Federal Certification Label status, odometer reading, and type of vehicle.
The VIN verification process ensures that the vehicle exists and that the VIN on the vehicle matches what is on the title. This process is a preventative measure to facilitate catching fraudulent activity and protects the public against theft and fraud.
In addition to the VIN verification, you will need your out-of-state title, MSO, or registration card, and possibly a smog certification, California Weight-master Certificate, or other documents depending on the type of vehicle you are registering.
The VIN verification process is used to bring vehicles not in the DMV database into the system, but it is also used in other scenarios, such as when a vehicle was in a tow yard and the owner needs to lift a lien authorized on file.
