Who owns CMCU containers
In the Navo24 Carrier Directory, CMCU belongs to Crowley, whose SCAC is CMCU. The line's profile, fleet and schedules are on its carrier page.
Crowley uses CMCU on its own equipment. Its other prefixes include SEFU.
A prefix tells you who owns the box, not always who books it. Crowley also runs leased containers under lessor prefixes, and other lines can carry CMCU boxes on slot or swap deals.
How to read a CMCU container number
Every container number has eleven characters under ISO 6346. The first three letters (CMC) are the owner code registered with the BIC in Paris. The fourth letter is the equipment category: U, freight containers: the dry, reefer, open top, flat rack and tank boxes that travel on ships, trains and trucks.
Then come six serial digits and one check digit. In CMCU4588222, a live number from our tracking demo pool, 458822 is the serial and 2 is the check digit. It is calculated from the first ten characters, so a single mistyped letter or digit almost always shows up as a wrong check digit.
How to track a CMCU container
Enter the full number in the box on this page: CMCU is already filled in, add the seven digits. Navo24 detects Crowley from the prefix, reads the line's own events (gate in, loaded, departed, transshipped, discharged) and adds the vessel's live AIS position and an ETA.
If the box is not found, it may not be on an active booking yet, or the digits may be wrong. Try the bill of lading or the booking number instead: they start with the line's code, often CMCU.
Questions about CMCU
Who owns CMCU containers?
Crowley.
How do I track a CMCU container?
Type the seven digits after CMCU into the tracking box on this page. No sign-up is needed for a single lookup.
What does the U in CMCU mean?
It is the ISO 6346 equipment category: freight container.
Is CMCU also a SCAC?
Yes. For Crowley the container prefix and the SCAC are the same four letters, which is common but not the rule.
Why does my CMCU number show a wrong check digit?
One character is probably mistyped: O and 0, I and 1, or two swapped digits. Check the number printed on the container door or on the bill of lading.
