Global Location Number (GLN)

A GLN is a unique number that is assigned to locations to enable them to be identified uniquely worldwide. GLNs can be used to identify any party/locations that you need to be uniquely identified for administrative and trading purposes. GLNs are particularly useful when automating processes as they allow computers to route information to the correct destination with no manual involvement. GLNs are used when identifying ship-to locations within Electronic Data Interchange (EDI) business messages, traceability systems and they can also be used in barcodes or RFID tags to identify a physical location.
