Vehicle Identification Number, also known as vehicle identification code in Chinese, is a set of codes assigned to a vehicle by the manufacturer for identification.
The VIN code is a code composed of 17 letters and numbers, also known as the 17-digit identification code, chassis number or 17-digit number. The vehicle identification code can be arranged and combined so that cars of the same model will not have duplicate numbers within 30 years. It has the unique identification of the vehicle, so it can be called a "car ID card."
The patent number is the number given when the patent right is granted and is a type of document number. The document number is the serial number compiled by each industrial property office when publishing patent documents (including public publication and copying only).
