How many digits does a vehicle frame number have?

[KatherineRose]

An vehicle frame number consists of 17 digits. The Vehicle Identification Number (VIN) is a unique set of numbers used on automobiles to identify the manufacturer, engine, chassis serial number, and other specifications of the vehicle. Since each manufacturer uses different codes, and every vehicle produced in the same factory has its own production sequence number, each vehicle manufactured in a specific year has a unique frame number. The meanings represented by the frame number: 1. Digits 1 to 3 represent the WMI code for the manufacturer, brand, and type; 2. Digits 4 to 8 indicate vehicle characteristics; 3. The 9th digit is a check digit; 4. The 10th digit represents the model year; 5. The 11th digit indicates the vehicle assembly plant; 6. Digits 12 to 17 are the sequential number.
