GB 16735-2019Road vehicle - Vehicle identification number (VIN) (English PDF)

1 Scope

China's mandatory national standard for the vehicle identification number. The VIN is the seventeen-character code stamped into every road vehicle, and it is the identity on which registration, insurance, theft investigation, safety recalls and export documentation all depend - one vehicle, one number, for the vehicle's life. Its structure carries meaning rather than being a serial: the first three characters are the world manufacturer identifier, the next six describe the vehicle's attributes, and the last eight identify the individual vehicle including the model year and the plant. The ninth character is a check digit computed from the others, which is what makes a transposed or invented VIN detectable rather than merely wrong. The standard specifies the content, the structure, the permitted characters - which exclude I, O and Q because they are confused with digits - and the marking requirements.

This Standard stipulates the content and structure of vehicle identification number, and the marking requirements and marking modification requirements of vehicle identification number. This Standard is applicable to automobile, and its incomplete vehicle, trailer, motorcycle and moped. Other vehicles that need vehicle identification number may also take this as a reference.
