What is the Difference Between Registering a Car Locally and Out-of-Town?

Differences between registering a car locally and out-of-town: 1. Different reissuance locations: If the vehicle license or license plate is lost, out-of-town registration requires reissuance at the vehicle's original registration location; local registration can be reissued at the local vehicle management office within the jurisdiction. 2. Different annual inspection procedures: For out-of-town registration, local inspection requires first obtaining a letter of authorization and other relevant procedures from the vehicle's original registration location before conducting the inspection locally; for local registration, simply bring the relevant documents to the local vehicle management office for inspection. License plates serve as identification and information registration for vehicles, primarily allowing identification of the vehicle's registered region and enabling tracing of the vehicle's owner and registration details.
