What is an mrn number?

MRN stands for Movement Reference Number. It is a unique reference number assigned to goods being imported or exported between countries. The MRN is generated by the Customs authorities of the country of export and is used to track the movement of goods throughout the supply chain. It is a crucial piece of information for customs clearance procedures and helps to ensure that goods are correctly identified and processed through customs checkpoints. The MRN is usually provided to the importer or exporter by their customs broker or freight forwarder.
