What Is a Chassis Number?

A chassis number is a unique identification code assigned to every motor vehicle. Often used interchangeably with the Vehicle Identification Number (VIN), this code helps track a vehicle throughout its life—from production to registration, service, and resale.

Also known as:

• VIN (in the U.S.)
• Frame Number
• Vehicle ID Number
• Body Number (in some regions)

It’s essential for checking a car’s history, validating its authenticity, and confirming there are no tampering or fraudulent claims.

Why Run a Vehicle Chassis Number Check?

Here’s what you can find out using a chassis number lookup:

✅ Vehicle specifications (make, model, engine type)
✅ Manufacturer origin
✅ Year of production
✅ Accident and damage history
✅ Title status (clean, salvage, rebuilt)

✅ Open recalls
