The Chassis number or VIN number is a unique identification code, by which manufacturers can identify their produced units worldwide. This number is also used to register cars in transport offices, and to register the background of a vehicle.
Are there two or more vehicles with the same VIN or Chassis Number?
The chassis number is like the fingerprint. There is no possibility that there is more than one vehicle with the same chassis number. This also serves for car registration, warranties, theft tracking, and identification with insurers.
This VIN number or chassis number has 17 digits which we will explain in detail.
What happens to a chassis number if it is not 17 digits?
When a VIN number is less than 17 digits, it is a car model whose year of manufacture is less than 1981. Before this year the chassis numbers were variable and ranged from 11 to 17 digits.
How to decode or translate a VIN Number
What do the numbers and letters in a VIN mean?
Global Manufacturer Identifier
In the first 3 (Three) numbers is the Manufacturer Identification Number (WMI). But if a manufacturer produces fewer than 500 vehicles in a period of one year then 9 is assigned to the third digit and positions 12 to 14 (The production number is assigned) indicate the second part of the WMI.
The first digit in the VIN indicates the vehicle’s country of origin or the final site where it was assembled. Usually this is the country where the car is produced, however in Europe it may be the country where the main factory headquarters is. Country Example:
|# VIN digit||Production Country|
|1, 4 and 5||U.S|
|S||UK United Kingdom|
The second digit in the chassis number or VIN indicates the manufacturer and the region where the car was produced.
The third digit indicates the type of vehicle eg Van, Suv, car, Truck.
