What if WeChat binds the mobile phone number without a verification code?

When wechat binds the mobile phone number, it will definitely let you fill in the mobile phone verification code.

If you don't have a verification code, WeChat official will not apply through binding.

If you bind someone else's mobile phone number, if the other person agrees, you can directly ask him for the SMS verification code he received when binding, and immediately fill it in the verification box to complete the binding.
