COSCO Tracking FAQ

Common questions about tracking COSCO shipments

How do I track COSCO containers?

Type the container number into the search box above: four letters and seven digits, such as CSNU1234560. The letters are the box owner's code, not the line's, so they vary: of the 3,058 COSCO containers tracked on Traqo, the most common start with CSNU (22%) or CSGU (16%), and leased boxes starting with TEMU (3%) or TRHU (3%). Our system detects the carrier from the number and retrieves the latest tracking information.

What container prefixes does COSCO use?

COSCO's SCAC code is "COSU". On Traqo we have seen 77 distinct ISO 6346 container prefixes from this carrier: CSNU, CSGU, TGBU, FFAU, UETU, OOCU, CSLU, OERU, and 69 more. The most active prefix is CSNU with 662 tracked containers.

Can I track using a Bill of Lading?

Yes! Switch to "BL" mode in the search box, enter your Bill of Lading number, and our system will retrieve all associated container and shipment details. This is useful when you have multiple containers under one BL.

Is COSCO tracking free?

Yes. You get 1 free container/BL lookup a day without an account, and a free plan that tracks 4 shipments, API included, no card needed.

How accurate is the tracking data?

We provide highly accurate data by connecting directly with COSCO's systems and terminal operators. Our data is updated regularly throughout the day with near real-time container movements and port activities.

How much COSCO data does Traqo have?

We have tracked 3,058 unique COSCO containers and 812 bills of lading on Traqo. Each tracking lookup retrieves current location, vessel information, ports, ETA and a complete event timeline directly from COSCO's systems.
