12306 What if I don't reply to the verification code?

Under normal circumstances, as long as the passenger sends 999 to 12306, it will reply the passenger to send the verification code in about 5 seconds. "Passengers with mobile phone authentication may experience network delay during centralized authentication, which makes it impossible to reply the verification code quickly." If the SMS cannot be verified normally after being sent n times, you can directly call the customer service phone number 12306 to inform the customer service staff, and the customer service staff will inform the verification code to help passengers complete the mobile phone verification. First, the user logs on to the website of 12306 and clicks on the "Personal Information" column under "My 12306" in the upper right corner of the page, where the mobile phone can be verified. Send SMS "999" to 12306 using the mobile phone number reserved at the time of registration. According to the received 6-digit verification code, passengers can fill in the 6-digit verification code in the blank box of the mobile phone verification webpage within 10 minutes, and click the "Verify" button to complete the verification of identity information and mobile phone information. In addition to the website, the railway 12306 mobile phone client has also started the mobile phone verification service. Although it can be verified at any time, the customer service staff of 12306 advises passengers to verify their mobile phones as soon as possible so as not to delay the purchase of tickets during peak hours.
