Who owns ZCLU containers
In the Navo24 Carrier Directory, ZCLU belongs to ZIM, whose SCAC is ZIMU. The line's profile, fleet and schedules are on its carrier page.
ZIM uses ZCLU on its own equipment. Its other prefixes include ZCSU, ZICU, ZIMU, ZMEU, ZMOU and ZWFU.
A prefix tells you who owns the box, not always who books it. ZIM also runs leased containers under lessor prefixes, and other lines can carry ZCLU boxes on slot or swap deals.
How to read a ZCLU container number
Every container number has eleven characters under ISO 6346. The first three letters (ZCL) 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 ZCLU1234564, a format example, 123456 is the serial and 4 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 ZCLU container
Enter the full number in the box on this page: ZCLU is already filled in, add the seven digits. Navo24 detects ZIM 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 ZIMU.
