What Is a VIN? The 17 Characters Explained
Updated 2026-07-01 · Sourced from NHTSA public data
A Vehicle Identification Number (VIN) is a unique 17-character code assigned to every road vehicle. Since 1981, the format has been standardized in the United States so any VIN can be read the same way.
Why VINs exist
The VIN lets manufacturers, dealers, insurers, and safety regulators identify one specific vehicle out of millions. It’s how a recall is matched to your exact car, how title and registration are tracked, and how parts are ordered correctly.
The structure
The 17 characters break into three sections — the manufacturer identifier (1–3), the vehicle descriptor (4–9), and the vehicle identifier (10–17), which includes the model-year character and the plant code. Valid VINs never contain I, O, or Q.
Where to find it
The most common spots are the driver’s-side dashboard (visible through the windshield), the driver’s door jamb, the engine bay, and your paperwork. Full walkthrough: where to find your VIN.
