The first step is to give the parcel to the operator for weighting, checking the destination (local, national, or oversees), as well as to specify the type of shipment (regular, priority, express, etc) so that a total fee can be calculated by the operator. The 2nd step is for the customer to provide the sender and receivers address on the parcel and/or to fill a form that is provided by the operator. The last step is to have the parcel registered with a tracking number by the operator, and to pay for the fees and get a receipt. This process is shown in the process flow diagram below.
