A container number is the unique identifier on a shipping container under the ISO 6346 standard: four letters (the owner prefix, ending in U for freight containers) followed by six digits and one check digit — for example MSCU1234567. The final check digit validates the number.
You can track a shipment by its container number, by bill of lading, or by booking reference.
