K Line (Legacy) container prefixes

Every intermodal container carries an ISO 6346 owner code — three letters identifying the owner, plus a single category letter (almost always U for freight containers). These four-letter prefixes are the fastest way to identify which carrier controls a given box. K Line (Legacy) has the following registered prefixes recorded in the BIC database. If a container in your possession begins with any of these codes, the box is owned by or leased on long term to K Line (Legacy).

To track a container under one of these prefixes, contact the carrier directly using the bill-of-lading number or container number. Most ocean carriers expose a public tracking endpoint on their website that accepts either format. K Line (Legacy) publishes its tracking page under the main kline.co.jp domain.

K Line (Legacy) corridor coverage

K Line (Legacy) concentrates its services on Bulk, Car carrier, ONE shareholder. Customers on these lanes typically see weekly or twice-weekly sailings depending on season and trade balance. For a current sailing schedule, contact the carrier directly or consult its weekly schedule publication.

How to track a K Line (Legacy) container

Tracking a K Line (Legacy) container starts with confirming the prefix. Look at the container's left-hand corner casting plate or the painted code on the door — the four-letter ISO 6346 owner code (e.g. KKFU) is followed by six numeric digits and a single check digit. If the prefix matches one in the list above, the box is on a K Line (Legacy) bill of lading. Visit kline.co.jp, navigate to the carrier's tracking or "track and trace" portal, and paste the full container number. The portal will return current vessel position, the next scheduled port call, the estimated time of arrival (ETA) and the most recent equipment events such as gate-in, loaded, discharged and gate-out.

If the carrier portal does not return a result, the most likely causes are: the container has not yet been gate-in at the origin terminal, the bill of lading number is in a different format (check whether the system expects an MBL versus an HBL), or the box is moving on a partner alliance vessel rather than a K Line (Legacy) hull. In the last case, the prefix still resolves to K Line (Legacy) as equipment owner but the schedule data lives with the operating carrier. K Line (Legacy)'s customer service can normally cross-reference the booking and route you to the correct alliance partner. Reach the carrier on +81 3 3595 5000 during European business hours.
