What is the difference between an order number and a CMR consignment note number?

An order number is assigned by the buyer or shipper — it references the commercial purchase order in the shipper's ERP system and appears on the commercial invoice, packing list, and CMR. A CMR consignment note number is assigned by the carrier — it references the specific transport movement in the carrier's TMS. On a single consignment, the order number tracks the commercial transaction from purchase order to invoice payment; the CMR number tracks the physical movement from collection address to delivery address. Go Trans confirms both reference numbers at the point of booking to ensure cross-system traceability between the sender's, carrier's, and receiver's IT systems.
