The registration policy of Pinduoduo's cross-border e-commerce platform Temu is that one identity information (such as ID card, passport, etc.) and mobile phone number can only register one Temu account. This is to prevent abuse of registration policies and ensure the fairness of the platform.

If you want to register multiple Temu accounts, you can try to change your identity information and mobile phone number to register. But please note that it is very important to comply with the platform's policies and regulations to avoid being punished for illegal operations. At the same time, in order to ensure the security of your account and avoid unnecessary trouble, it is recommended that you do not try to register multiple accounts easily.
