ONE Container Tracking

Six codes tell the merger story compactly. ONEU and MOAU are the post-merger house prefixes; NYKU remains registered to NYK, while KKFU, KKTU and KLFU sit under K Line — yet all of those fleets were folded into ONE’s operations, so every one of these numbers tracks on the ONE portal. The parents survive as shipping conglomerates; their container boxes now sail magenta.

Every bill of lading here opens with ONEY — a fourth letter that trips up tools expecting the U-suffix of equipment codes, and the giveaway that you are holding a document number rather than a box number. The same ecomm search field takes ONEY documents, bookings and container numbers, and the pre-filled link works for any of the three.

Append ?trakNoParam=YOURNUMBER to the cargo-tracking URL and the result loads without touching the search form — verified in a real browser, and exactly what our checker’s button does after validating the digit. That makes ONE results bookmarkable and shareable, a convenience only Maersk and PIL match among the lines we tested. The ONE app adds push updates on the same feed.

Not from the container. A standard dry box has no power, no radio and no satellite receiver — it is a steel case with a number painted on it, and it reports nothing about itself. Every position you see against a ONE (Ocean Network Express) shipment was reported by something else: a terminal crane, a gate reader, or the ship.

A live map on a carrier’s tracking page is almost always plotting AIS, the transponder every large vessel broadcasts with its position, course and speed. That is genuinely useful at sea: it is a real position rather than a schedule, and an ETA recalculated from actual movement. It is also the ship’s position, not your box’s, and the two part company the moment the container is discharged.

On land the map goes quiet. Between the gate-out and the delivery there is no vessel to follow, and the road leg appears only as whatever events the terminal and the trucker report. A container sitting on a chassis in a yard shows the last position of a ship it left days ago. Only specialised IoT equipment reports its own location, and wherever that exists it is a paid product sold to the shipper, not something a tracking page gives away.

How long a container spends at sea on ONE (Ocean Network Express) services, port to port. Each figure below is stated by two documents for the same service and the same pair of ports — the line’s own schedule and one more — and both are linked beside it. Where we could not find two, the pair is not listed.

These are schedule figures between two ports, not delivery times: add the days before the vessel sails and after it discharges, and expect the real voyage to drift by a few days either way. A line can change a rotation at any time, so check the date on each source.

The Asia–Europe figures are for the route around the Cape of Good Hope. On 18 October 2026 the lines’ own pages still sent these services that way; only ONE named services back through the Suez Canal (FE1, IOX). A return to Suez shortens the voyage by roughly ten days, so a figure here is out of date for any service that moves.

ONE operates in the Premier Alliance alongside HMM and Yang Ming, sharing vessels on the main east–west trades. As with every alliance, the ship named against your container may belong to a partner, and the name on your bill of lading is what decides where the events live. A ONE B/L tracks at ONE whichever of the three owns the hull.

ONE is also one of only three carrier trackers we opened with a live container number in the URL and found to load the result directly — the others ignored the parameter or were not tested. That is why this page can give you a finished link instead of a number to copy and paste.

You may have searched for the wrong company. This is the failure particular to ONE. Four of its six prefixes — NYKU, KKFU, KKTU and KLFU among them — are inherited from NYK and K Line, so people read the door, search for the parent company, and land on a corporate site with no container tracker on it. All six track at the same ONE page.

Check the number first. The checker here recomputes the check digit and will tell you whether a character was misread before you go anywhere.

Too new, or too old. ONE publishes its first event at gate-in or loading rather than at booking, and archives shipments some weeks after delivery. Both ends of that window return an empty result for a number that is perfectly valid.
