TEXU Container Prefix — Textainer (Leasing)
Textainer, a Bermuda-based lessor managing about four million TEU, became part of Stonepeak in 2024 and absorbed the Seaco fleet at the end of 2025.
Its register footprint is the widest of any lessor — seven codes including two inherited from Seaco — which makes Textainer prefixes the ones most often misread as carrier codes.

Frequently asked questions
Who owns the TEXU container prefix?
TEXU is registered to Textainer, a container leasing company (lessor) — the BIC register lists it together with TGHU, TEMU, TGBU, but the boxes sail in other lines' fleets.
Which line do I track a TEXU container with?
Not with Textainer — a TEXU 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 TEXU number there.
Is TEXU 8549784 a valid container number?
Yes — TEXU 854978-4 passes ISO 6346 validation: the weighted letter-and-digit sum for TEXU854978 leaves remainder 4 mod 11, giving check digit 4. The worked table for this TEXU example is on this page.
Is TEXU a shipping line prefix or a leasing company prefix?
TEXU is a leasing-company (lessor) prefix — Textainer owns the steel box, while a shipping line operates it, which is why owner and tracker differ.
