How to Decode a Chevrolet VIN to Reveal Engine, Trim Level, and Factory Build
Whether you’re shopping for a used Chevy or trying to better understand the one you already own, there’s a lot of value in learning how to decode a Chevrolet VIN (Vehicle Identification Number).
That string of 17 characters stamped on the dash isn’t just a random mix of numbers and letters—it holds the entire DNA of the vehicle, including key specs like:
• Engine configuration & displacement
• Trim level and series options
• Transmission type
• Assembly plant location
• Country of origin
• Model year
• Factory-installed features & packages
🔍 What Is a Chevrolet VIN?
A VIN (Vehicle Identification Number) is a permanent 17‑character ID assigned to every Chevrolet vehicle at the factory—no two VINs are the same.
You can find your VIN:
- Driver‑side dashboard (visible through windshield)
- Inside the driver door jamb
- Vehicle registration & title documents
- Insurance cards and service paperwork
Tip: Always verify the VIN on the vehicle matches paperwork to avoid fraud or title washing.
