Extended Knowledge

VIN is defined by ISO 3779 standard, 17 characters excluding I, O, Q to avoid confusion with numbers. The 9th check digit uses weighted sum mod 11 algorithm. WMI (World Manufacturer Identifier) in positions 1-3 identifies the maker. Position 10 indicates model year (letters and numbers cycle). Position 11 indicates assembly plant.
