ordrenummer

An ordrenummer (literally “order number” in Danish/Norwegian) is a unique identifier assigned to a purchase order in commerce. It serves as the primary reference for tracking, processing, and communicating about a specific order across sellers, couriers, and customers. In many systems, the ordrenummer is generated automatically by the seller's order management or ERP platform at the moment the order is created. It is typically alphanumeric, may include prefixes or timestamps, and is unique within the vendor's domain.

Common uses: the ordrenummer functions as the customer reference when contacting support, for tracking shipments, and for linking invoices, returns, and refunds. It is printed on order confirmations, packing slips, shipping notices, and invoices. It is distinct from a tracking number, which identifies the physical shipment, and from a purchase order (PO) number used internally in procurement.

Format and variation: formats vary by vendor and region. Some examples: ORD-20240523-00123; PO-9876; or 10001234. In multi-region systems, the ordrenummer may be combined with a regional code.

Security and privacy: order numbers themselves do not reveal payment details, yet they may be used to access order information in customer portals. Access should be controlled and protecting associated data is important.
