Homemade Vehicles and State-Assigned VINs
State-assigned vehicle identification numbers (VIN) are issued to homemade or rebuilt vehicles which do not have a VIN, and to vehicles which have more than one VIN.

Vehicle owners shall apply to WYDOT for a state-assigned VIN if:

• Any part of the vehicle on which the VIN appears is replaced
• A vehicle part containing the VIN is incorporated into another vehicle.

A Wyoming VIN can only be issued to Wyoming residents

.
The department shall determine that the applicant for the VIN is the lawful owner of the vehicle. The vehicle will require a VIN inspection to accompany the application. A Wyoming law enforcement officer must perform the inspection.
