Cautions for this scheme
- Decoded from GM's own VIN standards filed with NHTSA. A decode shows what the VIN says, not what the car is; it is not authentication.
- For 1981-1984 GM coded position 4 as the restraint system, position 5 as carline/series (one letter, per division) and positions 6-7 as the GM body type. Codes are sourced for 1984 only, and only for the 1984 pages GM re-filed: carline/series for Chevrolet, Pontiac and Oldsmobile, and the engine table. Restraint, body-type and plant codes for 1984, and all Buick 1984 series codes, were not found and decode as unknown code.
- GM prints the Hurst/Olds, Grand National, T-Type and Monte Carlo SS under their carline (e.g. Oldsmobile R Cutlass Supreme, Chevrolet Z Monte Carlo); the VIN has no separate code for these packages.
- Engine codes are GM corporate codes shared by all divisions; where GM lists more than one engine under one code, all are shown. The fuel column is printed as GM prints it (2 / 4 = carburetor barrels per GM's own typical-VIN wording, EFI, MFI, TBI, DFI, Die = diesel).
Decoded in full elsewhere
- CamaroFacts: Camaro VINs are decoded in full by CamaroFacts; this pack identifies the carline only.
- VetteFacts: Corvette VINs are decoded in full by VetteFacts; this pack identifies the carline only.
