More than any other single question, this one comes up the most. The Chevrolet Truck serial numbers are well documented, but us GMC guys are left out in the dark. Well smile because you are out in the dark no more on serial numbers from '39-'55. I can help you understand GMC's straight forward serial number system and what your truck's serial number will tell you about your truck. The links below go to individual pages of serial numbers and explanations. Start with the explanation and go forward from there printing pages that you need for your reference. Good luck

Start with the chassis serial number - NOT the title number or "VIN" but the number off of the ID Plate on the truck.

This page was created for Advance Design (1947 to 1955 1st series) and earlier GMC trucks. That doesn't mean that later years are not welcome, but the creator is primarily interested in pre '55 trucks.
