First, open and log in to the Traffic 12123 app on your phone's home screen. On the main interface of Traffic Management 12123, click on the "Service Center" in the bottom right corner. On the Service Center interface, click on the "Information Appeal" in the top right corner. On the User Information Appeal interface, enter the appeal reason, ID number, name, and phone number, then click "Next". Proceed to the next step for facial recognition, align your face to confirm your identity.

Last time I changed my number on my driver's license, I went directly to the DMV. The process wasn't complicated. Just bring your ID card and original driver's license, fill out an application form at the service window, and they'll verify your identity information and update the database. It usually takes one to two hours to complete, is free of charge, but may require waiting in line. I recommend avoiding peak hours to save time. After the update, it's best to check the traffic management app to confirm the information is synchronized. If you don't update your phone number promptly, you might miss important notifications like traffic violations or emergency contacts, which could affect your daily life and driving safety.

I updated my number using the 12123 Traffic Management APP, and it was super easy to do on my phone: log in to the account, find the Driver Information Management section, click to modify contact details, upload identity proof, and submit for review. No need to go out and queue, saving time and effort, and you can track the progress in real time. After the update is successful, remember to verify that the SMS notification is accurately received. When driving, if you encounter emergencies, the police can contact you via the new number, avoiding misunderstandings or delayed fines.

As a frequent driver, I suggest you prepare your original ID card and driver's license before changing your number, and go directly to the local traffic police station or vehicle management office to handle the procedure. The staff will verify your documents and have you fill out a change application form. The process is transparent and quick. Keep the receipt for future reference after completion. Updating this number promptly is very helpful for handling traffic violations and accident coordination, and it's also important for protecting personal information security.

The quickest way to change my number online: Open the traffic website, register and log in, go to the personal information page, select contact details update, upload the required scanned documents, and submit. The system review takes just a day or two, saving a lot of time compared to offline methods. Remember to check the validity of your number regularly when driving. If your car is towed or has issues, having an accessible contact can minimize trouble.

Last time I reminded my friend to update his driver's license number, he procrastinated until problems arose. The procedure is: bring ID card and driver's license to the DMV to fill out a change form or operate via APP. The key is to ensure smooth transition between old and new numbers without affecting emergency contacts. Timely updates help avoid legal disputes and make the driving experience more secure.
