FCIU Container Prefix — Florens (Leasing)
Florens is the leasing arm of the COSCO group, running a fleet of nearly four million TEU from Hong Kong — some of it leased to third parties, some circulating inside COSCO’s own services.
Two codes are registered plainly to Florens; a third Florens-registered code is treated as COSCO fleet equipment and covered on the COSCO pages.

Owner vs operator: the Florens case
Florens boxes often ride COSCO ships, but the register entry stays a lessor entry — track with whichever line issued your bill of lading.
Frequently asked questions
Who owns the FCIU container prefix?
FCIU is registered to Florens, a container leasing company (lessor) — the BIC register lists it together with FSCU, but the boxes sail in other lines' fleets.
Which line do I track a FCIU container with?
Not with Florens — a FCIU 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 FCIU number there.
Is FCIU 2266793 a valid container number?
Yes — FCIU 226679-3 passes ISO 6346 validation: the weighted letter-and-digit sum for FCIU226679 leaves remainder 3 mod 11, giving check digit 3. The worked table for this FCIU example is on this page.
Is FCIU a shipping line prefix or a leasing company prefix?
FCIU is a leasing-company (lessor) prefix — Florens owns the steel box, while a shipping line operates it, which is why owner and tracker differ.
