Where to find Buick VIN number

The VIN, or Vehicle Identification Number, serves as a unique identifier for a specific car and can be found in various places, such as:

  • On the driver's side of the dashboard, near the base of the windshield, visible from the outside through the glass.
  • At the point where the driver-side door jamb connects to the vehicle's frame when closed.
  • In automobile-related literature, like the owner's manual.
  • On documents such as the title, registration, and insurance policies, which can be stored at home, in the glove compartment, or in the trunk.
  • Embossed on the engine block, often located near the front of the engine.
  • On the frame or chassis of the vehicle.
  • On the transmission. It's worth noting that if a vehicle history report is available for the car, the VIN might also be listed on it. This report provides information about the vehicle's ownership, maintenance, and accident history.
