Who owns BLZU containers
In the Navo24 Carrier Directory, BLZU belongs to BLPL Singapore, whose SCAC is BLZU. The line's profile, fleet and schedules are on its carrier page.
BLPL Singapore uses BLZU on its own equipment.
A prefix tells you who owns the box, not always who books it. BLPL Singapore also runs leased containers under lessor prefixes, and other lines can carry BLZU boxes on slot or swap deals.
How to read a BLZU container number
Every container number has eleven characters under ISO 6346. The first three letters (BLZ) 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 BLZU1234563, a format example, 123456 is the serial and 3 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 BLZU container
Enter the full number in the box on this page: BLZU is already filled in, add the seven digits. Navo24 detects BLPL Singapore 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 BLZU.
Questions about BLZU
Who owns BLZU containers?
BLPL Singapore.
How do I track a BLZU container?
Type the seven digits after BLZU into the tracking box on this page. No sign-up is needed for a single lookup.
What does the U in BLZU mean?
It is the ISO 6346 equipment category: freight container.
Is BLZU also a SCAC?
Yes. For BLPL Singapore the container prefix and the SCAC are the same four letters, which is common but not the rule.
Why does my BLZU 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.
