Other VIN locations, sometimes referred to as anti-theft labels, can be found in numerous places. For instance, VINs are stamped or affixed to the front fender and bumper, the hood, the left and right door, rear quarter panels, the trunk and the rear bumper. Sometimes VINs are imprinted on rear passenger doors as well. The codes are also stamped on the engine, transmission and drive train to discourage reassembly of wrecked or stolen vehicles. And some, but not all, vehicles will also have the serial number positioned in confidential locations, such as under the carpets; on the interior of the vehicle's "A" post, the support that runs from the top of the front door along the windshield, or "B" post, the support that runs midway through the vehicle; and on firewalls.
