What Does the VIN Number Do for Semi-Trailers?

VIN number is very important for any vehicle and trailer, we can regard it as the ID card or fingerprint of the trailer. Generally, the VIN will be located on the front half of the semi-trailer on the driver’s side in a fixed position (can’t be on a moving part) because anyone must be able to read the VIN number from the outside.

Semi-trailers in China usually have the VIN number directly engraved on the frame or on the sign of the entire vehicle.

How to check the VIN number?

The VIN looks like a series of random numbers, but it is not the case. Each digit has its own unique meaning and ultimately constitutes a unique number.

  • First: Country
  • Second: Manufacturer
  • Third: Vehicle type
  • Fourth: Body type
  • Fifth: Engine
  • Sixth: Series
  • Seventh: Restraint
  • Eighth: Model
  • Ninth: Check digit
  • Tenth: Model year
  • Eleventh number: Plant
  • Twelfth-seventeenth: Sequential number

Through these numbers, you can find the history of this trailer, including:

  1. Theft Records
  2. Structural Damage
  3. Lien Records
  4. Damage
  5. Repossession Records

If you are buying a second-hand trailer, it is even more important to find the VIN number. It can help you:

  1. View the history of towing accidents
  2. Understand the past repairs
  3. Know the past car owners
