Vehicle Identification
All Peterbilt vehicles are identified by a 17–digit Vehicle Identification
Number (VIN). This unique numeral and letter combination
identifies the manufacturer, the model year it was
built, and other vehicle attributes. The VIN is in compliance
with 49CFR565, Code of Federal Regulations. As an example,
the model year and assembly plant are designated by a
letter in the tenth and eleventh character positions (see 4 and
5 below).
