There are two ways to check the car phone number: first, see if there is the owner's phone number. If not, you can check the phone number of the local vehicle management office through the license plate and ask the vehicle management office to provide the phone number of the owner. If you can't even find the phone number of the vehicle management office, you can call 1 14.

Some dmv will not directly provide the phone number of the owner to protect the privacy of the owner, but they will personally contact the owner and then give feedback to the person looking for the owner.

There are also two ways to check the car phone:

1. If the other party illegally parks, you can call 122 to contact the trailer. After receiving your alarm information, the police will generally inquire about the owner's information according to the license plate number and contact the owner to move the car. If the owner can't be contacted, they will call a tow truck to tow it away.

2. Call the other insurance company on the pretext of accidentally bumping into the other car when reversing, and provide the other car model and license plate number so that the customer service can inform the owner to handle the accident. In order to avoid their responsibilities, the insurance company will actively contact the owner to handle the accident. When the owner hears that his car has been scratched, he will come back soon.
