MSKU Container Tracking — Maersk-Owned Prefix
Track on maersk.com — official Maersk trackerMaersk's tracker accepts the container number directly in the link — the checker below builds it for you.
Maersk has been moving boxes since the dawn of containerisation and its fleet is second only to MSC. A century-old Copenhagen shipping house, it grew through the acquisitions of Sealand, P&O Nedlloyd and Hamburg Süd — and each purchase left its mark in the BIC register.
That is why the Maersk family spans eight prefixes: the heritage codes of absorbed lines still ride on the sides of thousands of boxes, all answering to the same maersk.com tracker.
