How to track a COSCO or ONE shipment by booking number
- Select your carrier — COSCO (COSCO Shipping Lines) or ONE (Ocean Network Express) — using the toggle above.
- Enter your booking number exactly as it appears on your booking confirmation or shipping instructions.
- Press Track. Results show your vessel name and voyage, port of loading and discharge, ETD and ETA, and the full container event timeline.
- No account, login, or credit card required — the lookup is free.
COSCO booking numbers are typically 10 digits (e.g. 6435740310). ONE booking numbers begin with ONEY followed by alphanumeric characters.
Where to find your BL number (Bill of Lading)
Your Bill of Lading (BL) number is the primary reference document for your ocean shipment once cargo has been loaded. You can find it on:
- The original Bill of Lading issued by your carrier or freight forwarder (top-right or top-center of the document).
- Your shipping confirmation email from the carrier — look for "B/L No.", "BL Number", or "Document Reference".
- Your freight forwarder's tracking portal or shipment status email.
- The carrier's own website after logging in with your booking reference.
If you only have a container number (e.g. CSNU6335911), try entering it as the reference — COSCO lookups support container number search as well.
