After conjecture and verification, some mechanisms for registering WeChat IDs were discovered.
When registering a WeChat account, you must fill in the mobile phone number, because the mobile phone number will be used to receive the verification code. The condition is that the mobile phone number is not currently bound by other WeChat accounts, even if you have used this mobile phone number to register the WeChat account before.
If the mobile phone number has been bound by a WeChat account, you can unbind it by changing the mobile phone number bound to the WeChat account.
Here's how to unbind
When changing the mobile phone number bound to the WeChat account, the WeChat account does not need to bind the mobile phone number, or the number of mobile phone numbers bound to the WeChat account is less than or equal to 1, which means it can also be 0. For example, wechat 1 is bound to mobile number A, wechat 2 is bound to mobile number B, wechat 1 can change the bound mobile number 1 to mobile number 2, and we will not be prompted to say mobile number B during this process. Wechat 2 has been bound and can be replaced successfully, then mobile phone number 1 is not bound to Wechat at this time, and it can be used to register a new Wechat.
Of course, most people may only have one mobile phone number, but they can have multiple mobile phone numbers by registering virtual mobile phone numbers on the network. For example, in addition to the real mobile phone number, there are also mobile phone numbers such as GV and TextNow, which can also be used to register WeChat, QQ, Weibo, etc.
