How an Oldsmobile VIN breaks down
Oldsmobile was a General Motors division, so its VINs follow GM's structure under the 17-character ISO 3779 standard. Positions 1–3 are the World Manufacturer Identifier — a US-built Oldsmobile commonly opens 1G3. Positions 4–8 encode the model line, body and engine; position 9 is the check digit; position 10 the model year; position 11 the plant; and 12–17 the sequential build number.
Oldsmobile production ended in 2004, so all Oldsmobile VINs cover models up to that year, including the Alero, Intrigue, Aurora and Silhouette. For pre-1981 Oldsmobiles such as classic Cutlass and 442 models, the shorter manufacturer-specific format applies — see our classic-car VIN decoder.
Decode vs. history: what the VIN can and can't tell you
Decoding an Oldsmobile VIN reveals the factory build — year, engine, plant and trim. It won't show what happened after the sale. For salvage, accident, flood and odometer brands, run the same VIN through a history report drawing on NMVTIS and state-DMV records — especially useful on an out-of-production brand.
Frequently Asked Questions

On the lower-left corner of the windshield and the driver-side doorjamb on 1981-and-newer models; on pre-1981 classics, check the dash plate, doorjamb and title.

1G3 is the World Manufacturer Identifier for a US-built Oldsmobile under General Motors. The following characters narrow it to the model line, body and engine.
