The SF number protects the recipient from finding the courier.

If the recipient's mobile phone number is hidden by SF, then the courier information can't be found on your mobile phone. If the recipient's mobile phone number is hidden by SF, then the courier information can't be found on your mobile phone. Because in this case, only the parties themselves can see it, and other outsiders can't inquire. You can call SF customer service to ask for help. We can call the hotline of SF official website, then explain the problem to the customer service, and ask the customer service to restore all the personal information and address of the user, so that we can query the logistics information normally. I think you may have blacklisted or blocked your mobile phone, so you can't find it. I suggest you go to the business hall to unseal it.
