CGMU Container Prefix Owner

CGMU is a container owner code associated with CMA CGM. Learn how BIC container prefixes identify equipment owners and operators.

Prefix: CGMU
Owner or operator: CMA CGM

The four-letter prefix CGMU appears at the start of ISO container identification numbers and is associated with CMA CGM.

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.

CGMU container number format

A container number starting with CGMU has the four-letter prefix, a six-digit serial number, and one check digit, for example CGMU1234567.

Who uses CGMU containers

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