What is the chassis number on the vehicle license?

[DelZane]

The chassis number refers to the Vehicle Identification Number (VIN) on the vehicle license. More relevant information is as follows: 1. The VIN is a 17-digit code composed of letters and numbers, also known as the 17-digit identification code, chassis number, or 17-digit number. 2. The combination of the vehicle identification code ensures that no two vehicles of the same model will have the same number within 30 years, giving it a unique identification for the vehicle. Therefore, it can be referred to as the "vehicle's ID card." The functions of the chassis number are as follows: 1. The chassis number follows certain rules. Illegal characters include O, Q, I, and 0. The letter Z is invalid in the year position. The ninth digit can only be a number from 0 to 9 or the uppercase letter X. The following four digits must all be numbers and cannot be letters. 2. The VIN standard can be used to analyze vehicle configurations. Digits four to eight represent the engine and transmission model, which must match the information on the assembly nameplate without any discrepancies.
