MBL Tracking FAQs
Everything you need to know about tracking Master Bills of Lading
What is a Master Bill of Lading (MBL)?
A Master Bill of Lading is the main contract of carriage issued by an ocean carrier / NVOCC. It lists the shipper, consignee, vessel, voyage and every container in the shipment, and customs requires it before cargo can be released.
How do I track a Master Bill of Lading online with TrackCargo?
Enter the MBL number—typically a four-letter carrier prefix (e.g. MAEU , MSCU , CMDU ) followed by 8–12 digits—into the search bar and press Track . The dashboard shows the latest carrier events, current status and the carrier-provided arrival date.
How often is your MBL-tracking data refreshed?
Carrier data refreshes on regular update cycles, so new milestones such as Loaded on Vessel , Discharged or Gate-Out appear as soon as posted by the carrier.
Which carriers can I track?
TrackCargo supports 20+ VOCC and NVOCC prefixes, including Maersk , MSC , COSCO , Hapag-Lloyd , ZIM and many regional lines. We add new carriers each month.
How many MBLs can I track on the trial plan?

Do you provide ETA details?

Can I use notifications for MBL updates?
Email notifications and webhook support are available on eligible plans. Event availability depends on the carrier data returned for the shipment.
