Container Number

Container Number is an alphanumeric code used in international container transport to uniquely identify each container. It typically consists of 4 letters (owner code + equipment category identifier) and 7 digits (serial number + check digit), e.g., 'MSCU1234567'. Usage scenarios include: booking, customs declaration, bill of lading, packing list, arrival notice, etc., for tracking cargo, verifying container information, and handling exceptions. Notes: The container number must be accurate; otherwise, it may lead to picking up the wrong container, delays, or extra costs. It must be distinguished from the seal number and bill of lading number: the container number identifies the container itself, the seal number is the lock number on the container door, and the bill of lading number is the transport contract number. Synonymous with 'box number', but 'container number' is more colloquial and commonly used in communication between freight forwarders and customers. Foreign trade practitioners should develop the habit of verifying the container number against container type and quantity to avoid losses caused by clerical errors.
