I received a SF pick-up code. Could it be fake?

Yes The mobile phone will receive an inexplicable courier pick-up code, which is directly related to the wrong mobile phone number recorded by the courier system. After the shipper's mobile phone number is entered into the courier system, the courier pick-up code will be sent when the goods arrive at the pick-up point. If you enter the wrong number, it will directly lead to the inexplicable courier pick-up code has not been received, which is caused by the telephone input error of the courier system.
