How to Change the Vehicle Owner's Mobile Number?

[StCali]

The vehicle owner needs to bring their original ID card to the internet service window of the vehicle management office (located inside the fee payment hall) to make the change. Direct login for changes. If the phone number used for registration is different from the registered phone number, the registration will not be successful. If the vehicle owner forgets the registered phone number, they can call the vehicle management office to inquire about the details. If necessary, the owner may need to visit in person. If someone else is handling the process on behalf of the owner, they must also submit the original ID card of the agent and a written authorization from the owner.
