Carriers, courier services, and parcel operators assign every shipment a tracking number – a unique alphanumeric identifier that keeps a consignment traceable from acceptance to final delivery. Shippers, consignees, and logistics providers use it to query current location, estimated delivery date, and handling status at any point in transit. In cross-border shipments, the tracking number serves as the primary reference for customs clearance and as proof of delivery. It should not be confused with an invoice number, which may cover multiple consignments, or a barcode, which simply encodes the number in machine-readable form.
