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 compliancewith 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).

Vehicle Identification Number (VIN)
Vehicle Identification Number (VIN)

The Chassis/Serial Number refers to the last seven characters of the VIN, including the assembly plant designator (eleventh character position) and a six-digit serial

 

number. This number will allow your Peterbilt Dealer to identify your vehicle. You will be asked for this number when you bring your vehicle in for service.

VIN Location

The VIN is marked on the Incomplete Vehicle Certification

Label (on trucks) or on the Tire, Rim, and Weight Rating

Data Label (on tractors). Both labels are located on the

driver’s door frame.
