The Movement Reference Number (MRN) is the registration and identification number provided by the customs authorities. This number enables shippers to monitor the status of their shipments at all times. The MRN appears in the top right-hand corner of the Export Accompanying Document (EAD) which the shipper receives from the customs office, and is an 18-digit chain of numbers and letters as well as a barcode. This number initiates the export procedure and enables the shipment of the parcel. Without an MRN it is not possible for a certificate of export to be issued.
