- JZNU
- Owner or operator
- Maersk Line
The four-letter prefix JZNU appears at the start of ISO container identification numbers and is associated with Maersk Line.
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.
JZNU container number format
