What is a VIN?
A Vehicle Identification Number (VIN) is a standardized 17-character code used on modern passenger vehicles. It never includes the letters I, O, or Q. Sellers, insurers, and history providers use the VIN to refer to one specific vehicle — not a plate that can change with registration.
How a VIN is structured
Exact field meanings vary by manufacturer, but most VINs follow this high-level layout:
Positions 1–3
WMI
World Manufacturer Identifier — country and manufacturer cues.
Positions 4–9
VDS
Vehicle Descriptor Section — model, body, engine, and related attributes (varies by maker).
Positions 10–17
VIS
Vehicle Identifier Section — model year coding, plant, and sequential production number.
