The itinerary code phone number is incorrect. I have appealed, but why has it not been changed?

It may be an upload error or network problem.

You can appeal again. Use the "I want to appeal" function at the bottom of the "Ankang Code" page, select "Incorrect registration information" as the appeal question type, select "Mobile phone number" as the error information item, enter the correct mobile phone number, and then upload the ID card photo as a voucher for appeal modification. .
