COSCO SHIPPING Lines container tracking

How to read a COSCO SHIPPING Lines container number

CBHU9853238 example only — not a real shipment

Container numbers follow ISO 6346, the international standard for freight-container identification: four letters, six serial digits, then one check digit. The first three letters are the owner code — registered with the BIC (Bureau International des Containers) — and the fourth letter is the equipment category (U for a standard freight container).

Take CBHU9853238 as a COSCO SHIPPING Lines-style example: CBHU is the registered prefix (owner code CBH plus the category letter U), 985323 is the serial, and the final 8 is the check digit computed from the ten characters before it — tracking systems use it to catch typos before they search.

If your COSCO SHIPPING Lines tracking isn’t working

1. 1 Check the number format first

   Container numbers are exactly four letters plus seven digits (like CBHU9853238). A common slip is confusing the letter O with zero, or dropping the final check digit. Copy the number from the door of the container or your booking confirmation rather than retyping it.

2. 2 Make sure the number was issued by this carrier

   If your shipment was booked through a freight forwarder, the number on your paperwork may be the forwarder’s own reference, which COSCO SHIPPING Lines’ system won’t recognise. Ask whoever issued your documents which carrier number to use — or paste the number on our homepage and we’ll work out who it belongs to.

3. 3 Too early or too late

   New shipments can take a little while to appear — most carriers only start returning results once the container is in their system after export gate-in or acceptance. Long-delivered shipments drop out too: tracking data is usually purged weeks or months after delivery.

4. 4 Still nothing?

   Your booking agent or COSCO SHIPPING Lines’ customer service can look the shipment up internally — have the container number and the issuing office or booking reference handy when you ask.
