Vehicle Identification Inspections

A vehicle inspection is also required for vehicles with title or paperwork issues and vehicles that cannot be identified due to a missing vehicle identification number (VIN).

The Registration Compliance Program is responsible for investigating cases of Arizona's residents who fail to comply with Arizona's registration laws.
