Where can the vehicle frame number be found?

The vehicle frame number is located at the lower left corner of the windshield. Other common locations include: the vehicle registration certificate, which clearly displays the frame number; the insurance policy, which may have it attached or recorded; and the vehicle's model identification plate. Below is a detailed introduction to the vehicle frame number: Introduction to the vehicle frame number: Also known as the Vehicle Identification Number (VIN), it is a unique 17-character alphanumeric code that serves as the car's identification. Each vehicle has its own unique frame number. The letters and numbers in the frame number represent information such as the vehicle's production region, manufacturer, production year, and model. Detailed interpretation of the frame number: Positions 1-3 (WMI): World Manufacturer Identifier. The first digit indicates the country or region of production, while digits 2-3 represent the manufacturer and vehicle type. Positions 4-9 (VDS): Vehicle Descriptor Section. Digits 4-8 indicate the vehicle's category, series, body type, and engine type, among other details. The 9th digit is a check digit. Positions 10-17 (VIS): Vehicle Identifier Section. The 10th digit identifies the production year. The 11th digit is the assembly plant code. Digits 12-17 represent the production sequence number.
As a seasoned professional who frequently handles vehicle documentation, I've found that the most common location for the VIN is on the exterior lower corner of the windshield near the driver's side, easily visible from outside the car when looking down at that metal or paper label—especially noticeable in good daylight. Another spot is inside the driver's door frame or B-pillar, where a small embossed plate is often affixed; you'll need to crouch slightly to spot it. Additionally, never overlook the vehicle documents—such as the first page of the registration certificate or the record at the top of the insurance card—keeping backups makes reference convenient. The VIN serves as a car's identification card, essential for transfers, insurance, or recall events—simple yet critical, so I make it a habit to check during car washes to ensure it's unobstructed or un-faded. If all else fails, a small plate near the firewall in the engine compartment can be a lifesaver—just remember to use a flashlight for assistance.
