Frequently asked questions
Who owns the TGCU container prefix?
TGCU is registered to Touax, a container leasing company (lessor) — the BIC register lists it, but the boxes sail in other lines' fleets.
Which line do I track a TGCU container with?
Not with Touax — a TGCU 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 TGCU number there.
Is TGCU 2665719 a valid container number?
Yes — TGCU 266571-9 passes ISO 6346 validation: the weighted letter-and-digit sum for TGCU266571 leaves remainder 9 mod 11, giving check digit 9. The worked table for this TGCU example is on this page.
Is TGCU a shipping line prefix or a leasing company prefix?
TGCU is a leasing-company (lessor) prefix — Touax owns the steel box, while a shipping line operates it, which is why owner and tracker differ.
