Track COSCO Shipment by Booking or BL Number — Free
Look up any COSCO ocean container by booking number or bill of lading — no login to COSCO's website required. Portly fetches live vessel, route, ETD/ETA, and container status directly from COSCO's tracking system.
How to track a COSCO shipment without logging in
COSCO Shipping Lines — one of the world's largest ocean carriers — operates thousands of containers across every major trade lane. When a COSCO shipment is booked, the carrier issues a booking number (typically 10 digits) that uniquely identifies your cargo. Once the vessel departs, a bill of lading (BL) number is issued as the formal shipping document.
Portly connects directly to COSCO's public tracking endpoints so you can check shipment status, current vessel and voyage, estimated departure (ETD) and estimated arrival (ETA), and the full container event timeline — all without creating a COSCO eSHOP account or navigating their portal.
COSCO booking numbers are typically 10 digits long (e.g. 6435740310). Container numbers follow the standard industry format: a 4-letter prefix followed by 7 digits (e.g. CSNU6335911). Both formats are accepted above.

Frequently Asked Questions
What is a COSCO booking number?
A COSCO booking number is the unique reference your freight forwarder or shipper receives when space is reserved on a COSCO vessel. It is typically 10 digits (for example, 6435740310). Use it to track your shipment before or after the bill of lading is issued.
What is the difference between a booking number and a bill of lading (BL) number?
A booking number is issued when cargo space is reserved — it is available before the vessel departs. A bill of lading (BL or B/L) number is issued after cargo is loaded and the shipping document is signed. For COSCO, you can track with either reference. Portly accepts both.
Can I track a COSCO shipment by container number?
Yes. COSCO container numbers follow the standard 4-letter prefix + 7-digit format (e.g. CSNU6335911). Enter the container number in the field above and Portly will look up the latest status directly from COSCO's public tracking system.
How often is COSCO tracking data updated?
Portly fetches data live from COSCO's official tracking endpoints every time you search — there is no cached data that might be stale. Milestone events (loaded, departed, arrived, discharged) are updated by COSCO at each port of call, typically within a few hours of the actual event.
Do I need to log in to COSCO's website to track my shipment?
No. Portly queries COSCO's public tracking system on your behalf. You do not need a COSCO account or any login credentials. Just enter your booking number or BL number and press Track.
