Why can I only enter 6 numbers in my world verification code?

According to relevant information, in the short message sent to you by my world official, my world short message verification code consists of 6 digits, and the valid time is 1 minute. You need to input the information in time after receiving it. If SMS authentication fails, you can perform the following steps:

1. Go to the account to check the real name information first. You can't play games until you pass the exam. If it fails, modify it yourself.

2. The server itself is eavesdropped, and network fluctuation makes it impossible for a large number of players to enter. Wait until the official repair is completed before logging in to the game.
