CMAU Container Prefix Owner

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

Prefix: CMAU
Owner or operator: CMA-CGM

The four-letter prefix CMAU 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.

CMAU container number format

A container number starting with CMAU has the four-letter prefix, a six-digit serial number, and one check digit, for example CMAU1234567.

Who uses CMAU containers

CMAU 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.
