Prefix: KWMU
Owner or operator: Unitainer

The four-letter prefix KWMU appears at the start of ISO container identification numbers and is associated with Unitainer.

A complete container number combines the owner prefix, six-digit serial number, and check digit. The prefix identifies registered equipment ownership and does not always identify the carrier currently transporting the container.

Use the CargoEnter container validator to check the number structure before starting shipment tracking.
