TRACKINGMCP · All container prefixes ↗
A container number beginning with TRIU is a leased box owned by Triton — a container-leasing company, not a shipping line. The box is leased to whichever carrier is moving it, so you can't identify the carrier from the TRIU prefix alone. Track it by its bill of lading or booking number with the operating carrier.
| Prefix | TRIU |
|---|---|
| Owner | Triton |
| Type | Leasing company (leased box) |
Every shipping container carries an ISO 6346 number: four letters then seven digits (six serial + one check digit). The first three letters are the owner code and the fourth is always U for a freight container — so the four-letter prefix identifies who owns the box. Owner ≠ always the line carrying it: leasing companies own millions of boxes that sail under many carriers, which is why a leasing prefix is tracked by bill of lading, not by the prefix.
No. TRIU is a container-leasing prefix owned by Triton. The box is leased to a carrier, so track it by bill of lading rather than by the TRIU prefix.
Enter the bill of lading or booking number with the carrier that's actually moving the TRIU box — the leasing owner (Triton) doesn't operate the sailing.
