First and foremost, kindly request the traveler to provide a valid identification card and their travel ticket. During the package delivery, make an effort to deliver the package to the permanent residence address of the traveler or their family at the origin whenever possible. To avoid any ambiguity and misunderstandings, it is recommended to draft a simple document between the traveler and the package sender. This document should include the details and quantity of the items in the package, as well as the information of the traveler and the package sender. Both parties should sign this document in two copies. Make sure to request the traveler/package sender to provide their contact number in the origin and destination countries for any additional information and immediate communication. These measures contribute to ensuring the successful delivery of the package and establishing secure relationships between the traveler and the sender.
