Container Prefix Tracking
CMAU Container Tracking – CMA-CGM
Track CMAU containers associated with CMA-CGM. Check the ISO number format, owner identity, carrier milestones, and missing-update guidance.
- 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 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.
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.

Enter the full CMAU number to request events. CMAU is a known prefix for CMA CGM, but leased or exchanged equipment can travel with another shipping line, so check the operating carrier if nothing appears.
