What Does a Container Number Mean?

Reading the identification

A container number identifies the equipment used to carry a shipment. Under the BIC identification system, it contains a three-letter owner or principal-operator prefix, an equipment category letter, a six-digit serial number and a final check digit. The category letter U identifies a freight container.

The check digit helps detect mistakes when a number is recorded or transmitted. It is not a statement about the contents of the container or the condition of the goods.

Using the number in shipment records

Keep the full equipment number with your shipment reference. When you receive documents or a loading update, compare the complete number rather than relying on the last few digits. Ask your freight contact to resolve a mismatch before you use the documents for the next step.

A container number is different from a booking reference, bill of lading number or seal number. Record each in its own field so the equipment, transport documents and seal can be checked separately.

What it does not confirm

The number alone does not tell you which products were loaded, how many cartons are inside or when delivery will take place. Use the agreed packing list and transport information for those questions. For a mixed FMCG shipment, retain the product-level packing information alongside the equipment reference.
