12123 will display the transferred vehicle due to software update delays. You only need to wait a few days for it to update. Here is the relevant information: 1. Documents required for vehicle transfer: original owner's ID card, new owner's ID card, original and copy of the vehicle license, purchase tax certificate, vehicle and vessel tax payment proof, vehicle registration certificate, vehicle inspection report, and policy. All of these must be provided in original. 2. Previous owner's information cannot be removed: Vehicle transfer refers to changing the owner's name, and each vehicle has its own identity proof. The vehicle account is used to register the owner's information and home address, as well as related vehicle parameters. After the transfer, the previous owner's information can only be viewed through institutions like the police station or prosecutor's office. The original owner's information before the transfer remains as administrative vehicle management information and cannot be removed.

I recently helped a friend with a similar issue where the vehicle information was still visible on the 12123 app after the transfer. This is mainly due to a delay in the traffic system's data update. There's a buffer time required for the transfer information to be submitted by the vehicle management office and synchronized to the 12123 platform. It usually takes a few days or even one to two weeks for the information to completely disappear. This is because the backend processes large amounts of data and uses a batch update mechanism to ensure stability, making real-time changes impossible. I recommend not to worry and check the app again after a week. If the information still appears after two weeks, contact the local vehicle management office to verify if the transfer process was fully completed. The residual data is temporary and won't affect daily use, but it's important to check promptly to avoid confusion with vehicle records. This is quite common, so be patient as the system will catch up.

I also encountered the issue of 12123 displaying old information after my car was transferred. The key point is that your account might still be bound to that vehicle. After the transfer, you need to manually unbind the vehicle or re-add the new car in the 12123 settings, as the system won't automatically remove the association. If you don't take action, the historical data remains for checking any outstanding violations or issues. I've tried refreshing the app, clearing the cache, or logging in again, which sometimes resolves the issue. I recommend you open the app now, go to the vehicle management page, and check the binding list to remove the old car. This process is simple and quick, and the data usually updates promptly after unbinding to ensure the new information is accurate. Remember to maintain your account regularly to avoid similar minor annoyances.

After the transfer, if the information is still visible on the 12123 platform, it's likely that the transfer process hasn't been fully completed. For example, the transfer registration at the vehicle office might not have been fully entered into the system, or there might be missing signatures or documents. When I go through a transfer, I always request to receive the electronic confirmation on the spot and check whether the transfer record has been confirmed and submitted. If there's any oversight in the backend processing, the data might remain for a few days. It's advisable to take the transfer documents to the vehicle management office to verify and confirm the status. A simple check can clarify the situation, so there's no need to worry about security risks. The data retention is a buffer period set to handle potential disputes. Addressing it promptly ensures all records are transferred perfectly.

After the vehicle transfer is completed, the 12123 app still displays the old information. I suspect it might be a minor system bug or temporary database lag. Data transmission could have been interrupted, causing residual data. Try restarting the 12123 app to force a refresh, or log out and log back in to activate new data synchronization. Sometimes server periods can also delay updates. I've encountered similar issues multiple times, and simple operations usually resolve them. If it still doesn't work, contact the 12123 customer service and report the specific vehicle number—they can quickly correct it in the backend. Data delays don't affect daily driving; it's just a lag in the interface display, so don't worry too much.

I understand that the reason for retaining post-transfer information on 12123 is due to historical data preservation policies, such as when dealing with legacy violations or ownership disputes, these records may be needed. The system defaults to retaining them for several months to ensure a smooth transition. However, if you want to completely clear them, you can go to the account settings in 12123 to add the new vehicle and remove the old association. This does not take effect automatically and requires manual intervention to ensure the transfer is thorough. It is recommended to regularly check your account status, and handle the information the day after the transfer to avoid accumulation and confusion. Overall, it is safe and harmless, so there's no need to worry.
