a courier initialling means that the courier item has been signed, but the courier company staff can't recognize it because of the scrawl, but the goods have been received.

generally, it means that the express goods do not reach the recipient according to the normal process, such as the address of the recipient is not written in detail, which leads to the goods being stranded in the local logistics center. It is more common for the recipient to pick up the goods at home, and the signature of the recipient is abbreviated. For example, only write the last name, not the first name, or sign for it (not the recipient's name).
