What each VIN position means on a Cadillac

Every vehicle sold in the United States since 1981 carries a 17-character VIN under federal standard 49 CFR 565 (international standard ISO 3779). The letters I, O and Q are never used, to avoid confusion with the digits 1 and 0.

17-character VIN structure
Positions 1–3	World Manufacturer Identifier. Position 1 identifies the country of assembly. On a Cadillac it is 1, 4 or 5 (built in the U.S.A.; 2 if built in Canada, 3 in Mexico). Positions 2–3 identify the manufacturer and vehicle type — 9 WMI codes are registered to Cadillac (full table below).
Positions 4–8	Vehicle Descriptor Section. Model, body style, engine, restraint system and transmission, as coded by the manufacturer.
Position 9	Check digit. A number (0–9) or X, computed from the other 16 characters with a weighted modulus-11 formula. It detects typos and tampering — validate one here.
Position 10	Model year code. A repeating 30-year cycle (Y = 2000, 1 = 2001, …).
Position 11	Assembly plant. Manufacturer-assigned plant code.
Positions 12–17	Serial number. Unique production sequence of the vehicle.

Position meanings 4–8 are manufacturer-specific. Decoding the VIN returns the exact decoded values — see our data sources.
