Every Sealand box carries an ISO 6346 number: four letters (the owner prefix), six digits and a check digit. Sealand prefixes include SEJJ, MCPU and MHHU. Enter the container number, the bill of lading or the booking reference and Navo24 detects which one it is.
The tracker joins Sealand's own events (gate out, loaded, departed, transhipped, discharged) with the vessel's AIS position, so you see where the box is now, not where it was at the last port call.
Before booking, compare sailings on your lane by transit time and real on-time reliability across all carriers, Sealand included where it publishes schedules.
For the price, FreightRatesMCP shows market rates for 20GP, 40GP and 40HC on a port pair. After arrival, demurrage and detention start once Sealand's free time runs out, and Navo24 counts the days left on every box.
Sealand's Standard Carrier Alpha Code is SEAU.
Sealand containers use the owner prefixes SEJJ, MCPU and MHHU, followed by six digits and a check digit.
