After the vehicle transfer is completed, it can no longer be checked on 12123. Since the vehicle's personal information involves some private details, the transfer of vehicle ownership cannot be queried via or website, hence it cannot be found on 12123. The required documents for vehicle transfer are as follows: Types of vehicle transfer: Individual to company: Vehicle license, registration certificate, vehicle invoice, seller's ID card, seller's photo at the DMV, vehicle inspection (no violations), company organization code certificate copy with official seal (2 copies), application with official seal, blank paper with official seal. Company to company: Vehicle registration certificate, valid compulsory insurance, both parties' enterprise code certificates and official seals (copy, buyer's original), sales agreement, issuance of used car transaction invoice; fill out the transfer form at the DMV and process at the relevant window. Individual to individual: Vehicle license, vehicle registration certificate, vehicle purchase tax certificate, road maintenance fee receipt, insurance policy, vehicle and vessel use tax certificate, ID card.









I just transferred my car to someone else, and a few days later when I checked the 12123 app, I could still see the previous violation history and vehicle information, but the new owner's real-time data wasn't updating. This is because after the transfer, the vehicle ownership changed, and my account still retains historical access permissions, such as being able to view past records, but new violations or operational functions are locked. It's recommended that the new owner download the app and rebind their account by entering the license plate and ID verification. By the way, if the transfer process was completed at the DMV, there might be a delay in system synchronization. Don't panic if the app interface doesn't refresh immediately; wait a day or two and check again. Remember, after the transfer, make sure to hand over everything clearly, including the app part, to avoid issues. Like the time I forgot, my friend couldn't check the new tickets.

As a new owner of a , I immediately tried checking the vehicle's condition through the 12123 app after completing the transfer. However, the previous owner's account was no longer functional. The new owner needs to log into the app, add the vehicle again, and input the VIN code along with relevant information to bind the account. Only then can I check for traffic violations in real-time and schedule services. After the transfer, the previous owner might still access some historical data, but definitely not any new updates. What I learned is not to overlook the app when purchasing a transferred vehicle—test the new binding on the day of handover to ensure it works smoothly. Once the DMV data syncs, the app will match accordingly, sometimes within just a few hours. The process is simple but crucial to avoid disputes over responsibility for new tickets later on. Regularly checking the app to ensure everything is in order is a wise practice.

After discussing in the car owner community, the impact on the original owner after vehicle transfer completion on the 12123 APP is that they can still view historical violation records, but the editing function for new data is no longer available. Once system ownership is transferred, control of the vehicle is handed over to the new user. The new owner needs to register the APP with their own and bind the vehicle to manage it. In practice, there might be a slight delay, so it's recommended to wait for the system to refresh after the transfer. If there are any doubts, directly contact the official customer service for verification. APP binding marks the start of a new journey, eliminating the risk of confusion.

I'm interested in the backend mechanism of the APP. After the vehicle transfer, the 12123 system will map the vehicle to the new user's database, and the original account will only have read-only access to historical data without the ability to perform new operations. For example, after transferring my old car, my APP still displays the vehicle information but the operation buttons disappear. Data synchronization relies on updates from the DMV, and binding a new vehicle is a basic action. Checking history is still possible, but new matters require new . It's most reliable to verify the status using the VIN on the DMV's official website. A simple refresh in the APP will adapt to the changes.

As the vehicle owner's responsibility, after transferring the vehicle, I confirmed that the historical records are still visible on 12123 but new features are disabled. Ownership changes mean control is transferred. The new owner must register the APP with their credentials and bind it. Safety reminder: The original owner should check that the vehicle identification is removed from the APP, and the new user should set it up immediately. Handling the APP after transfer is a crucial step—don't overlook it. The vehicle management records are authoritative; the APP is just auxiliary. To avoid disputes, it's recommended to document the handover status and maintain smooth communication.
