Where to Check the Vehicle Identification Number?

The vehicle identification number (VIN) can be found in several locations, including the lower right corner of the front windshield, door hinge pillar, door lock pillar, engine compartment, and the vehicle registration certificate. The vehicle identification number, abbreviated as VIN, is also known as the chassis number. It consists of a unique 17-character alphanumeric code that ensures no duplication for 30 years, effectively serving as the vehicle's ID. There are two main formats for VINs: the first is the ISO 3779 standard adopted by the European Union, and the second is primarily used in North America. How to interpret the VIN: The first character represents the country or region of manufacture, the second character identifies the vehicle manufacturer, and the third character indicates the vehicle type. Characters 4 through 8 describe vehicle attributes such as model, series, body type, etc. Characters 9 through 11 represent the check digit (calculated using a standard weighted formula), model year, and assembly plant. If there is no assembly plant, the manufacturer may specify other details. Characters 12 through 17 denote the vehicle's production sequence number. The role of the VIN: Also referred to as the vehicle's ID, the VIN provides information about the country of manufacture, the manufacturing company or plant, vehicle type, brand name, model series, body style, engine type, model year, safety equipment specifications, check digit, assembly plant name, and production sequence number. The VIN has many critical uses. For example, service providers use the VIN to identify the manufacturer's engine, transmission, and braking system configurations to offer more appropriate services for the vehicle.

I'm the kind of person who always gets lectured by mechanics about how hard it is to find my VIN during maintenance. Over time, I've figured out a few spots: the most obvious one is at the bottom left corner of the windshield (under the wiper), visible without even opening the door. There's also one on the door frame plate of the driver's seat—just crouch down and pull back the weatherstrip to reveal it. If it's covered in dirt, check inside the engine bay. For example, Volkswagens have it near the battery, while Toyotas place it on the firewall (don’t forget to bring wet wipes to clean off the grime). When buying a used car, I once found the VIN stamped under the spare tire well, but that required lifting the carpet. It’s best to snap a photo and save it on your phone—it can save you 20 minutes of queuing during license plate registration or inspections.

Last time I helped a friend check for flood-damaged cars, I found that the VIN is like a car's ID number. Japanese cars tend to hide it under the front passenger seat—you'll need to slide the seat all the way back and bend down to feel for it. American cars often place it on the upper left corner of the dashboard, where you can reach in from outside the windshield gap to feel the raised characters. When repairing accident-damaged cars, pay extra attention: some cars have clearer stamped numbers on the A-pillar than the B-pillar, and the engine block side also bears stamped numbers, though you'll need to remove the protective cover. A reminder to everyone: use specialized rubbing paper instead of tape when making imprints—the lady at the DMV said tape leaves marks and gets rejected.

When I first learned to drive, the instructor taught me that the Vehicle Identification Number (VIN) is the combination of letters and numbers at the bottom left corner of the windshield. For SUVs like the Toyota RAV4, you might need to lean over the hood to see it clearly. Later, when handling insurance claims, I learned that the original location is actually in the engine compartment—for example, Mercedes-Benz places it on the shock absorber mount, while BMW has it on the side of the longitudinal beam. Once, while helping a neighbor with her car transfer, I found the VIN of her old Nissan Sylphy in the middle of the spare tire, with a stamped imprint on the wheel hub. A tip: before tracing the number on a rainy day, use a hot air blower to dry the grooves of the stamped imprint, or else the ink paste will smudge.
