12345 is a nationwide public complaint hotline, which can consult, complain and report, and can inquire about the external consultation telephone numbers of government agencies and institutions, but cannot inquire about the owner information of personal telephone numbers.
For the owner information of the phone number, please dial 1 14. If the phone number has been reported or registered 1 14, it may be found. If it is a private mobile phone number, it can't be found because it involves personal information and needs protection.
