Why does my 12306 registration always say that the verification code is wrong? I obviously lost its right! I've tried it a dozen times and it's always like this! !

It is a network problem, and the solution is as follows:

1. First open the mobile phone page and find the railway 12306 client, as shown in the figure below.

2. Then on the personal center page that opens, find and click Register, as shown in the figure below.

3. Enter the following page and fill in your real information as required.

4. After filling in the information as required, put a tick in the small box before agreeing, and then click Next.

5. After clicking "Next", you will enter the following page. After reading the prompt carefully, click Send Registration SMS and send SMS 999 to 12306. The mobile phone will receive the verification code replied by 12306.

6. Enter the verification code within 10 minutes as required, and then click Finish Registration. The platform of 12306 will verify the identity information within 24 hours, as shown below.
