What is a reference number?

The shipper's reference is a unique identifier assigned to the shipment by the sender while filling out the shipment information. This can be any combination of letters and numbers, such as a purchase order number or any other information that allows you to manage your shipments. Use the Track by reference feature to view a group of shipments by their shared reference number.
 The more specific and unique your reference number is, the quicker it will be for your results to be displayed.
