A master B/L is issued by the ocean carrier or its agent and is usually the reference most directly connected to the carrier's shipment data.
A house B/L is commonly issued by a forwarder or NVOCC. It may map to a master B/L, but a carrier source may not recognize the house reference on its own.
Use the carrier-recognized B/L and select the corresponding shipping line. If the reference is rejected, verify whether it is a house B/L and obtain the master or carrier reference.
Keep the customer or house reference in CargoScope's customer-reference field while using the recognized carrier B/L for tracking.
CargoScope shows confirmed milestones from the available carrier and terminal sources. If the carrier has not provided an ETA, the shipment stays in a waiting state; CargoScope does not turn historical averages or an AI guess into a customer-facing arrival date.
The Bill of Lading remains the parent shipment while discovered containers appear in a compact selector. Operators can search by the parent reference or a child container and still land on the appropriate shipment journey.
