Every shipping container carries an ISO 6346 number: four letters then seven digits (six serial + one check digit). The first three letters are the owner code and the fourth is always U for a freight container — so the four-letter prefix identifies who owns the box. Owner ≠ always the line carrying it: leasing companies own millions of boxes that sail under many carriers, which is why a leasing prefix is tracked by bill of lading, not by the prefix.
MGSU containers are owned by Marguisa (SCAC MGSU).
Track a MGSU container by its number on Marguisa Shipping — or use TrackingMCP's Marguisa Shipping page.
