Motor vehicle driving license is an important certificate of insurance underwriting, and a lot of important vehicle information can be obtained through driving license. The domestic motor vehicle model registered on the driving license is compiled according to the coding rules of automobile product model, and the usual form is product trademark+product model name. If the driving license of imported cars is registered in the form of brand (Chinese or English)+model similar to that of domestic cars, brand+VIN (/kloc-part of 0/7 digit VIN code) will be used in more cases.
