After transferring the vehicle to someone else, you cannot find the vehicle in the Traffic Management 12123 system because the vehicle's personal information involves certain privacy details, making it inaccessible via phone or website. The methods to check are as follows: 1. Vehicle Management Office: You can personally visit the local vehicle management office with your ID card and a copy, along with proof of vehicle ownership transfer, to inquire. This is the most common method. 2. Online Inquiry: Check on a traffic violation inquiry website. Although the purpose is to check violations, the website displays the owner's details. 3. Registration Certificate: You can review your vehicle registration certificate, which includes all changes related to the vehicle.

I just sold my old car last week, and it still showed up in the 12123 system for three days. Actually, after the transfer procedures are completed, it takes time for the DMV system to update to the traffic management platform. Here's what you should do now: Open the APP and manually delete the vehicle information first, otherwise it might affect subsequent handling of traffic violations. In some areas, you also need to visit an offline window to update your documents—my neighbor encountered a situation where records could still be checked two weeks after the transfer. When binding a new car, it's recommended to use the same account, otherwise the system can get confused. If you're really worried, calling the 12123 hotline directly to urge them to update the data is the most effective.

Here's a pro tip from an experienced driver: It's normal for the 12123 app to display your old vehicle after transfer, as there's a delay in system synchronization. My advice is to log into the app immediately after the transfer – go to the personal center, find vehicle management, and unbind/delete the record of that car. If left unprocessed, the system might keep sending traffic violation alerts. Remember to have the new owner promptly register and update their info, which will automatically deactivate the original owner's association in the traffic management system. License plate changes get updated faster in the database, whereas keeping the original plate may cause information retention issues. The process is quicker than expected – it usually refreshes within five days at most.

According to the vehicle management office's working mechanism, the previous owner's vehicle list in the 12123 app will indeed retain records after a successful transfer. But don't worry, this is just a transitional period for system data synchronization, lasting up to one week at most. It is recommended that you actively unbind the vehicle: enter the APP, click on 'Registered Vehicles' > select the corresponding license plate > delete the vehicle. This operation is actually very important, otherwise you may not receive the verification code for the new license plate. This happened with my Ford Fiesta during the transfer process—I accidentally triggered the violation query function and got my account locked. After data clearance, you'll need to re-authenticate permissions with facial recognition.
