Who owns SMCU containers
In the Navo24 Carrier Directory, SMCU belongs to SM Line, whose SCAC is SMLM. The line's profile, fleet and schedules are on its carrier page.
SM Line uses SMCU on its own equipment.
A prefix tells you who owns the box, not always who books it. SM Line also runs leased containers under lessor prefixes, and other lines can carry SMCU boxes on slot or swap deals.
How to read an SMCU container number
Every container number has eleven characters under ISO 6346. The first three letters (SMC) 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 SMCU1186441, a live number from our tracking demo pool, 118644 is the serial and 1 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 an SMCU container
Enter the full number in the box on this page: SMCU is already filled in, add the seven digits. Navo24 detects SM Line 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 SMLM.
