12123 will display the transferred vehicle due to software update delays. You just need to wait a few days until the system update is completed, and it will return to normal. Vehicle transfer refers to changing the name of the vehicle owner. Completing the vehicle transfer legally finalizes the transfer of ownership and ensures the legality of the vehicle's origin. Documents required for vehicle transfer: Original owner's ID card, new owner's ID card, original and duplicate vehicle license, purchase tax certificate, vehicle and vessel tax payment proof, vehicle registration certificate, vehicle forensic inspection report, and policy. All documents must be provided in original. Vehicle transfer process: Issue a transaction invoice and pay the used car transaction tax. Private accounts are charged 1%, while corporate accounts are charged 4%. Vehicle inspection: Drive the vehicle to the inspection site for external inspection, engraving, license plate removal, and photography. Collect the vehicle photo and attach it to the inspection record form. Proceed to the transfer hall to complete the filing procedures. License plate selection: Take a number from the dispenser and queue with relevant materials to pay the transfer fees. Transfer and relocation: Required materials include the vehicle registration, transfer, and cancellation form, transfer application form, inspection record form, original vehicle property registration certificate, original license, original owner's ID card, original license plate number, vehicle photo, and transfer invoice from the trading market.

I just finished the transfer process and noticed that the 12123 app still shows the previous owner's name, which gave me a start. Actually, this is quite normal—it takes time for the DMV's system to sync with 12123, usually a couple of days at best, but sometimes up to one or two weeks. If you're in a hurry to handle online services, don't rush to operate directly in the app. Accidentally paying the previous owner's traffic fines would mean throwing money away. You can try logging out and back in, or uninstalling and reinstalling the app—some say this trick works. If it hasn’t updated after a month, chances are the DMV process is stuck. In that case, the safest bet is to take your new vehicle title to the DMV counter and verify your identity with a face scan.

Last month, I specifically asked this question while helping a friend with the transfer process. The staff at the vehicle office said that data synchronization relies entirely on the system's automatic updates, and delays in displaying updates on the 12123 app are quite common. They recommended checking the registration certificate and ID information for synchronization first after the transfer, as these offline records update faster than the app. If you're in a hurry to handle traffic violations or annual inspections, it's best to avoid using the 12123 app temporarily and visit the vehicle management office directly for the safest option. In case of app lag, try updating the app version or call the 12123 customer service hotline to request an update, providing your license plate number for them to refresh the data in the backend.

A dealer told me that at least three out of ten transferred vehicles show lagging updates on the 12123 platform. The core issue is the buffer period for data exchange between the internal DMV system and the internet platform, especially for cross-province transfers where delays are more noticeable. During this period, pay special attention: avoid using the original account to handle traffic violations, and for critical services like annual inspections, it's better to go to the service window. A useful trick is to completely close the app's background process and restart it, which is more effective than simply logging out. If the previous owner hasn't cleared all their traffic-related matters, the system may intentionally withhold data updates.

I encountered this issue when a used car last year. The delay in displaying information on 12123 is mainly due to the time difference in data synchronization between local vehicle management offices and the national platform. After successful transfer at the vehicle management office, it takes at least 48 hours for data processing. During this period, avoid clicking any confirmation buttons in the app, especially options like registering a non-personal vehicle. Making a mistake would require a trip to the vehicle management office to unlock. To quickly update, try applying for an electronic inspection mark on 12123 to trigger a forced system refresh. If there's no change after seven days, bring your new vehicle license to the vehicle management office and use the self-service machine to reset with your ID card.

I checked the 12123 app the day after transferring the car ownership, but it still showed the previous owner's name. A traffic police friend explained that after the physical records are updated at the DMV, the online system synchronization typically takes an average of 3 working days. Don't foolishly handle any business under outdated data, or the new owner might inexplicably receive traffic violation records. After transferring ownership, it's recommended to do three things: manually unbind the old vehicle, update contact information at the service hall, and then re-register the account with the new license plate number. The most aggressive approach is to file a complaint to 12345 to push for system updates, which works exceptionally well.
