I received the verification code of Xi 'an Bank's mobile banking registration. What's going on here?

Generally, in this case, if it is not the user's own operation, the user's identity information may be leaked.

Others are using user identity information to register electronic channels, or other users are handling related services, but they have filled in the wrong mobile phone number, resulting in an error when sending verification code information. Because of the first possibility, in order to ensure the safety of user account funds, it is suggested that users report the loss as soon as possible after receiving such information, or bring their valid identity documents and bank cards to the bank counter to check the account opening situation, so as to prevent others from using them fraudulently.
