JZNU Container Prefix Owner

JZNU is a container owner code associated with Maersk Line. Learn how BIC container prefixes identify equipment owners and operators.

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

A container number starting with JZNU has the four-letter prefix, a six-digit serial number, and one check digit, for example JZNU1234567.

Who uses JZNU containers

JZNU is registered to Maersk Line. Leased or exchanged equipment can move with a different shipping line, so the prefix alone does not identify the carrier of a shipment.
