Where to find GMC VIN number

The unique identification number, which is a specific code, can be found in several locations, such as:

  • On the driver's side of the dashboard, near the windshield base, which is visible from the exterior through the glass.
  • On the frame where the driver-side door hinge is attached to the car when it's closed.
  • In automobile literature, such as the owner's manual.
  • On documents such as the title, registration, and insurance policies, which can be kept at home, in the glove box, or in the trunk.
  • On the engine block, which is often located near the front and may be engraved.
  • On the frame or undercarriage of the vehicle.
  • On the transmission. Note that if a vehicle history report is available for the car, the unique identification number may also be listed on it. This report contains information about the vehicle's ownership, maintenance, and accident history.

The Vehicle Descriptor Section (VDS) is a part of the VIN that contains detailed information about the vehicle's model, body style, engine type, and transmission. It typically consists of six to seven characters that can be used to identify the vehicle's original configuration and check for any modifications.

The Vehicle Identifier Section (VIS) is another section of the VIN that provides specific information about the vehicle, such as the model, body style, engine type, transmission, and other characteristics. The VIS usually consists of six to eight characters, which can be used to identify the vehicle's factory of manufacture, build sequence, and production year.

Buying a used GMC? Reliability, problems & recalls

Reliability. RepairPal rates GMC 3.0 out of 5.0, ranking it 22nd out of 32 car brands, with an average annual repair cost of $744. Consumer Reports places GMC among the five lowest-scoring domestic brands in its 2025 reliability survey, partly driven by below-average scores on the redesigned 2025 Terrain and Acadia. J.D. Power's 2025 Vehicle Dependability Study (VDS) ranks GMC 7th overall, above the industry average, though the VDS measures owner-reported problems per 100 vehicles rather than long-term mechanical failure rates. The overall picture is average-to-mixed reliability depending on model and model year. Source: repairpal.com
