Choose the right SeaLand reference
Sealand is listed under SEJJ in CargoScope's coverage catalog. Its supported standalone inputs are container number, Bill of Lading or booking number. Select the reference type that matches your document; changing the input label does not turn an unsupported reference into a supported one.
- container number: Use the complete equipment number, including its final check digit. It identifies one box; the number's owner prefix alone does not prove which shipping line operates the voyage.
- Bill of Lading: Use the transport document issued by the selected line or NVOCC. A forwarder's house reference and the ocean line's master reference are not interchangeable; confirm the issuer before starting.
- booking number: Use the booking confirmation issued by the selected company. A booking can precede the allocation of a container, so container links and movement events may appear later.
SEJJ identification and coverage
The Sealand catalog entry also recognizes MCCQ, SEAU. These identifiers resolve to the same SEJJ entry, so choose one matching line instead of opening a separate shipment for each alias. Catalog aliases are not a list of container ownership prefixes.
- Sealand is listed as a shipping-line entry. Its catalog code identifies the tracking selection, not a guarantee of data for every vessel, route or terminal.
Follow the SeaLand shipment after it is found
CargoScope keeps the available journey events and the shipping line's ETA on the shipment record. A result can be incomplete while the line is still linking equipment or publishing a movement. Keep estimated dates separate from confirmed events, and use the last reported update to judge freshness. A terminal arrival is not a release instruction: confirm pickup permission, holds and free time with the responsible facility.
What you'll see in CargoScope
Each SeaLand shipment becomes one record with a journey summary: the port of loading, the port of discharge, the final destination and the line's ETA.

Questions
Which references can CargoScope use for SeaLand?
The 2026-09-30 coverage snapshot lists container number, Bill of Lading or booking number for Sealand (SEJJ). The authenticated workspace checks current availability; the public guide cannot enable a tracking route.
Why might my SEJJ shipment have no updates yet?
Confirm the selected company and reference type first. A valid reference may still have no published events, or the line may be temporarily unavailable. A missing update is not proof that the container has not moved. Keep an existing shipment and its history rather than creating duplicates to force a refresh.
Does this page mean CargoScope has a direct partnership with SeaLand?
No. It describes the references listed in CargoScope's tracking catalog. It does not claim an official partnership or direct access to every terminal and railroad on the shipment's route.
