What Is a Car Chassis Number?
The chassis number (VIN) is a 17-character alphanumeric code that serves as your car’s fingerprint. No two vehicles have the same VIN, making it a key identifier for:
✔ Vehicle history checks
✔ Registration & insurance
✔ Recall and warranty information
✔ Preventing fraud in used car sales
Where to Find Your Car’s Chassis Number
The VIN is typically located in several places:
1. Dashboard (Driver’s Side)
Look through the windshield at the lower corner—most cars display the VIN here.
2. Driver’s Side Door Jamb
Open the door and check the sticker on the door frame.
3. Under the Hood
Check near the engine bay or firewall.
4. Vehicle Registration & Insurance Documents
Your car’s paperwork will always include the VIN.
5. Under the Spare Tire or Trunk
Some manufacturers place the VIN in these locations.
How to Decode a Chassis Number (VIN Breakdown)
A 17-digit VIN is structured like this:
