Strictly speaking, a mobile phone number can only register one micro signal. Yes, the operation is to unbind the mobile phone number registered with the micro-signal to QQ number or other mobile phone numbers, so as to register a new micro-signal with the mobile phone number, but in theory, the mobile phone number has nothing to do with the unbundled micro-signal, so it is not allowed to say which micro-signal is registered.

A mobile phone number can only be bound to one micro-signal. If there is no binding, you can register up to five. The upper limit of micro-signal registration is 5, but this is the upper limit of registration within one year. Micro-signal and QQ number registration are different. QQ number application needs SMS verification, and WeChat also needs it, but the micro signal will synchronize the previous data with the new micro signal. Of course, there is only one chance to use the ID number for micro-signal real-name authentication.

Extended data

A micro-signal can only bind one real-name information. The real name information cannot be changed after binding, and the real name binding relationship will not be deleted when unlocking the card.
