GTIU 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.
GTIU is often mislabelled as an independent leasing code, but the BIC register places it with MSC’s fleet.
