Yang Ming Tracking. Free & Online.

Yang Ming Marine Transport Corporation keeps a Cargo Tracking page under the eBusiness menu of its website, and its search asks for a Container No., B/L No. or Booking No. TrackParcel uses only the first of those three. It sends one container number and reads the event table returned for that box.

B/L and booking searches come back in a different form that TrackParcel does not read, so those references stay on the carrier's own page. The status wording below comes from a saved real reply for a box shipped from Shanghai towards Rotterdam.

A container number here is a three-letter owner code, a category letter U, J or Z, a six-digit serial and one check digit. The line's own units start YMLU or YMMU, and for those two prefixes Auto-Detect suggests this carrier alone. For a box with any other owner code it is not suggested, so pick it from the list yourself.

Before sending, TrackParcel strips spaces and hyphens from the typed box number, plus any pasted prefix like AWB:. If a number that reaches the Yang Ming lookup still does not fit the container shape, including a B/L or booking reference shaped differently, it is answered as not found and never sent.

TrackParcel shows the default event table, newest move first. Each row keeps the carrier's event wording and the facility, for example a named Shanghai Yangshan terminal, and where given, its remarks carry the next port, the vessel and voyage and the discharge-port ETA.

If that table is empty, TrackParcel falls back to the DCSA-style table and keeps only its Actual rows. The customer booking reference and the vessel code are never read, and the answer has no shipper or consignee fields.

Clocks are facility local time with no zone. For ports on its built-in list, such as Busan, Shanghai or Rotterdam, TrackParcel reads that port's zone and shows the time in IST, labelled IST; other places keep the printed clock.

That sentence is the carrier's answer for a number it holds nothing under. The message goes on to suggest a typing error, asks you to check the BL No., Booking No. or Container No., and mentions the local office. TrackParcel shows this answer as not found.

A maintenance flag, a block flag or a web page in place of tracking data shows as unavailable instead. A container answer without one readable move is reported as an error rather than an unknown box.

The Local Office page of yangming.com, headed Office & Agent, is where the not-found message also sends you. That reply asks anyone with a question to contact the local office for further checking. Have the container number ready, plus the B/L or booking number if you hold one.
