You can usually find your car's VIN number attached to several places. The main location to look at is on the placard at the bottom of the windshield on the driver's side. There will be a little slot where the windshield meets the hood with the VIN stamped onto the metal placard. The VIN is also listed on the car's paper title document, on a placard inside the driver's side door, stamped on the engine, stamped on the main drivetrain components, on the bottom of the rear trunk, or on the car frame.
