One mobile number can apply for multiple stores, and the specific number depends on the restrictions of the platform. For example, some platforms allow each mobile number to apply for up to 3 stores, while other platforms have no clear restrictions. However, it should be noted that each store needs to be operated and maintained independently. If the number is too large, it may bring a greater burden to the merchant. In addition, when applying for multiple stores, merchants also need to pay attention to whether they meet the regulations and conditions of the platform to avoid being punished by the platform.
