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 complete number to request available tracking events. If no events appear, confirm the operating carrier because leased or exchanged equipment can move under another shipping line.
UNDU container number format
A container number starting with UNDU has the four-letter prefix, a six-digit serial number, and one check digit, for example UNDU1234567.
Tracking a UNDU container
Enter the full UNDU number to request events. The prefix identifies the owner, but leased or exchanged equipment can travel with another shipping line, so check the operating carrier if nothing appears.
