What a 1G9 VIN tells you

1G9 is a world manufacturer identifier — the first three characters of any 17-character VIN. It's assigned to GM (special / low volume) and tells you two things immediately: who manufactured the vehicle, and where. The leading character "1" is the ISO 3780 region code for United States; the second and third characters narrow it to the specific manufacturer and, for larger manufacturers, the vehicle class or division.

What the WMI does not tell you is the model, the year or the trim. Those live further along the VIN: positions 4 to 8 describe the vehicle attributes, position 10 encodes the model year, and position 11 identifies the assembly plant. To get any of that you need the full 17 characters — paste one into the box above and the decode runs against NHTSA's official records.

What car has a VIN starting with 1G9?

What does 1G9 mean in a VIN?

1G9 is a world manufacturer identifier (WMI) — the first three characters of the VIN. It's assigned to a specific manufacturer by the national authority (SAE in the United States) and identifies who built the vehicle and in which country.

Can I get full specs from a 1G9 VIN?

Yes, if you have the complete 17 characters. Enter the full VIN above and NHTSA's vPIC database returns model, trim, engine, transmission, body class, assembly plant and factory safety equipment, along with any open recall campaigns. The three-character WMI on its own only identifies the manufacturer and country.
