How to read a GMC VIN

GMC shares platforms with Chevrolet trucks and SUVs, so its VINs run close: 1GT for trucks and 1GK for SUVs, built primarily in the U.S. The first three characters — the World Manufacturer Identifier (WMI) — are the fastest tell. These are the GMCprefixes you'll see most often:

1GT
GMC trucks built in the U.S. — Sierra, Canyon
1GK
GMC SUVs built in the U.S. — Yukon, Acadia
3GT
GMC trucks built in Mexico

These are the common prefixes, not an exhaustive list — manufacturers add and retire WMIs over time. The decoder above always reads the authoritative record from NHTSA. For the full breakdown of all 17 VIN positions and the model-year chart, see the main VIN decoder guide.
