Prefix: UNDU
Owner or operator: Unitainer Trading GmbH

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

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.
