What number is the verification code of health code sent to SMS?

The verification code of the health code is sent to you by your mobile phone operator.

When registering the health code for the first time, you need to obtain the authorization to bind the mobile phone number. Your mobile phone operator will send the verification code only after the owner of the binding confirms the authorization. After you enter the verification code, the health code is bound to the mobile phone number. If there is anything in the future, you can contact me through this mobile phone number.
