Reading a Vehicle Identification Number (VIN) on a semi truck is a quick and easy way to determine the year, make and model of the truck. The VIN is usually located on the driver’s side door near the bottom corner.
It may also be printed in various other places, such as on an identification plate inside the cab or on the engine block. To read a VIN number, it helps to understand what each letter or number in the sequence means.
First three digits:
The first three digits of the VIN are known as the World Manufacturer Identifier (WMI). This code will tell you where and when the truck was manufactured.
For example, Ford trucks made in North America have a WMI of 1FT. The first digit (1) means that it was manufactured in North America, while FT stands for Ford Truck.
Fourth to eighth digits:
The fourth through eighth digits of a VIN represent its features and specifications, such as body type and engine size. These codes vary from one manufacturer to another, but you can usually find them listed in an online database.
Ninth digit:
The ninth digit of a VIN is known as its check digit. This single-digit code helps verify that your VIN is legitimate and not counterfeit.
To calculate this digit, you can use an online calculator or consult with your vehicle’s manufacturer.
Conclusion:
Reading a semi truck’s VIN number is an important step towards understanding its history and specifications. By understanding each letter or number in the sequence, it’s possible to identify where and when it was manufactured, as well as its features and specifications. It’s also important to remember that there will be a check digit at the end of every valid VIN number which verifies its authenticity.
