MSMU Container Tracking — MSC-Owned Prefix
Track on msc.com — official MSC tracker
MSC, the Geneva-based Mediterranean Shipping Company, runs the largest container fleet on the planet — over 800 vessels. Family-owned since 1970, it overtook Maersk for the #1 spot in 2022 and kept buying ships.
A fleet that size burns through serial numbers fast, which is why MSC registers eight owner codes; MSCU and MEDU carry most of the volume, with the rest of the family filling specialised pools.
