TRLU Container Prefix — Triton International (Leasing)
Triton International is the world’s largest container lessor — roughly seven million TEU of boxes that it owns but never sails, renting them to nearly every major line.
Five codes mark Triton steel, and seeing one tells you who owns the box — never who is moving it.

Owner vs operator: the Triton International case
A Triton-prefixed box in your booking means the line rented it that week; Triton’s own systems hold no voyage data at all.
Frequently asked questions
Who owns the TRLU container prefix?
TRLU is registered to Triton International, a container leasing company (lessor) — the BIC register lists it together with TCLU, TCNU, TCKU, but the boxes sail in other lines' fleets.
Which line do I track a TRLU container with?
Not with Triton International — a TRLU box is leased, so the tracking data lives with the shipping line named on your booking confirmation or bill of lading; open that line's tracker and paste the TRLU number there.
Is TRLU 7552483 a valid container number?
Yes — TRLU 755248-3 passes ISO 6346 validation: the weighted letter-and-digit sum for TRLU755248 leaves remainder 3 mod 11, giving check digit 3. The worked table for this TRLU example is on this page.
Is TRLU a shipping line prefix or a leasing company prefix?
TRLU is a leasing-company (lessor) prefix — Triton International owns the steel box, while a shipping line operates it, which is why owner and tracker differ.
