MSC Container Tracking

Track on msc.com →

MSC moves more boxes than anyone on earth, which makes “MSC container tracking” one of the most-searched phrases in shipping. The lookup itself is free and needs no account — what trips people up are the prefixes, the MEDU-vs-MSCU confusion, and a tracker that quietly refuses pre-filled links.

Everything on this page comes from data we verified against the BIC register and tested in a real browser. Start with the checker: it catches typos and confirms the box is actually MSC-registered before you go anywhere.

MSC container prefixes: MSCU, MEDU and six more

Most MSC boxes stencil MSCU, but the fleet spans eight registered owner codes — including GTIU, which surprises people because it doesn’t spell anything MSC-like. All eight resolve to “MSC — Mediterranean Shipping Company” in the BIC register, and all eight track identically on msc.com.

If a box shows a different prefix but sails on an MSC vessel, it is almost certainly leased tonnage (TRLU, TGHU and similar) — the tracker still finds it by number, because MSC reports events for every container it operates, owned or not.

MSC B/L numbers: why they start with MEDU

MSC switched its bill-of-lading prefix from MSCU to MEDU in April 2018 — an official customer advisory, not a rumor. Documents from before the switch (and some regional legacy paperwork) still show MSCU, and the tracker accepts both. A booking reference is a separate, usually all-numeric string; the msc.com search takes any of the three from the same field.

Using the msc.com tracker

We tested it directly: the MSC tracker ignores URL parameters, so no site can deep-link you to a result — anyone claiming to is just opening the empty search page. Copy the number from the checker above, paste it at msc.com, and use the “Notify me” button on the result to get e-mail updates instead of re-checking. The myMSC app (iOS/Android) shows the same feed with push notifications.

MSC overtook Maersk as the world’s largest carrier on 5 January 2022 — built almost entirely by organic growth and a famous buying spree of second-hand ships. It left the 2M alliance in January 2025 and now sails alone, with slot partnerships (including one with ZIM on Asia–US East Coast lanes).

Frequently asked questions

Why does my MSC bill of lading start with MEDU, not MSCU?

MSC changed its B/L prefix to MEDU in April 2018 by official advisory. MSCU remains the dominant container prefix and appears on older documents; the msc.com tracker accepts both forms.

Is GTIU an MSC container?

Yes — GTIU is one of MSC’s eight registered prefixes in the BIC register, despite not resembling the brand name. Validate any GTIU number in the checker above and it will resolve to MSC.

Can I get a link that opens my MSC tracking result directly?

No — msc.com strips URL parameters and always opens an empty search; we confirmed this in a real browser. Copy the number and paste it — or use the myMSC app, which remembers your shipments.

Does MSC tracking need an account?

No — the public tracker at msc.com/en/track-a-shipment is free and anonymous. An account (or the myMSC app) adds saved shipments and notifications, nothing more.

Why does my MSC container show no events yet?

MSC publishes the first event after gate-in or loading, typically within 24–48 hours of the box entering its system. A booking made yesterday has nothing to display — that is normal, not an error.

How do I track an MSC container that was transshipped?

Track by B/L (MEDU…) rather than container number — the shipment-level view updates through hub ports more reliably, and MSC routes heavily through transshipment hubs like Gioia Tauro and King Abdullah Port.
