FREE TOOL · OFFLINE WMI TABLE
VIN decoder — instant lookup
Decode any 17-character Vehicle Identification Number. Returns the World Manufacturer Identifier (WMI), country of assembly, segment, model year, and validates the check digit (position 9) per ISO 3779.
What this tool reveals
- Positions 1-3 — World Manufacturer Identifier (WMI): country + maker + sub-segment.
- Positions 4-8 — Vehicle Descriptor Section (VDS): model, body, restraint, engine code (maker-specific).
- Position 9 — ISO 3779 check digit. Mathematically validated by this tool.
- Position 10 — Model year code (we decode 2001-2030).
- Position 11 — Plant code (maker-specific assembly facility).
- Positions 12-17 — Serial number.
For deeper decoding of the engine code from positions 4-8, look up the maker's VIN format guide or use a paid VIN service. This tool covers the universal ISO 3779 portion + a hand-curated WMI table for 80+ tunable makers.
