OOCL Container Tracking
Hong Kong’s most storied container line keeps a distinctly independent digital life inside the COSCO group: its own portal, its own app, its own documentation series. For tracking purposes, treat OOCL as a standalone carrier — group ownership changes nothing about where the data lives.
Two prefixes cover the whole fleet, which keeps validation simple; the checker below confirms the digit math before you face the portal’s login-free but bot-wary search page.

OOCL prefixes: OOLU and OOCU
Just two codes are registered here — OOLU on the vast majority of boxes and OOCU on the rest — both resolving to Orient Overseas Container Line in the BIC register. Leased tonnage rounds out capacity as it does everywhere, so cargo booked with OOCL can travel in a lessor’s box that still reports events under your OOCL booking. Prefix structure follows the standard ISO 6346 owner-code scheme.
OOCL B/L numbers: OOLU on paper too
Unusually, OOCL’s documentation prefix matches its main equipment code: bills of lading also begin with OOLU, followed by a longer numeric string than a container number carries. Length is how the tracker tells them apart, so paste the full document number rather than trimming it to look container-shaped. Booking references from My OOCL Center work in the same field.
Using the OOCL tracker and My OOCL Center
Expect a hard bot wall: automated queries get challenged aggressively, which is why third-party sites so often show stale or missing OOCL data. In a normal browser the cargo-tracking search is free and account-less, while My OOCL Center (moc.oocl.com) adds saved shipments and documents for registered users. Since January 2025 the mobile side is the new “OOCL” app, which replaced the retired OOCL Lite.

Founded in Hong Kong in 1969 by the Tung family, OOCL was acquired by COSCO in July 2018 for $6.3 billion yet still operates as a separate brand — which is also why Alphaliner counts its ships inside the COSCO group figure rather than ranking it on its own line. It sails in the Ocean Alliance.
Frequently asked questions
Can I track an OOCL container on the COSCO website?
No — despite common ownership since 2018, the two carriers maintain separate portals, so OOLU and OOCU numbers return nothing on eLines and must be searched at oocl.com.
What happened to the OOCL Lite app?
It was retired when the new “OOCL” app launched in January 2025. The replacement covers tracking, schedules and notifications; OOCL Lite no longer receives data.
Why does my OOCL bill of lading look like a container number?
Because both start with OOLU. The B/L continues with more digits than the 6+1 a container carries — enter it whole and the tracker recognises it as a shipment document.
Why do tracking aggregators fail on OOCL boxes so often?
OOCL’s bot protection is stricter than most carriers’, so scrapers get blocked and show gaps. The official search in a regular browser remains free and reliable.
Where does OOCL rank among the world’s carriers?
Nowhere separately — Alphaliner folds its fleet into the COSCO group total, which ranks fourth worldwide. As a brand, OOCL keeps its own network, paperwork and tracker.
Does OOCL tracking require a My OOCL Center account?
No — the public cargo search works without registration. An account adds shipment management, documentation access and alerts on top of the same event data.
