Tik Tok needs real-name authentication. We can try to register with different mobile phone numbers, choose different birthday dates and genders, and submit different photos and videos as auxiliary materials. If you want to do real-name authentication based on the existing Tik Tok number, you need to unbind the bank card, WeChat, QQ and other third-party accounts of the original account and cancel it, and then re-register a new number for real-name authentication. For accurate information, please consult Tik Tok customer service.
