on the telephone numbers shown in the invitation, you must select and call the number corresponding to your address.
to reship your shipment more promptly, make sure you can answer the following questions in advance: the addressee, address, item number, date and time when the courier attempted to deliver the consignment, the date and time when the re-delivery could take place.

inaccurate recipient information

If the shipment does not contain complete information about the recipient — only your name, part of your name, or only your last name — the postal worker cannot verify that you are the person entitled to receive the shipment.  
in the following cases:
