NYKU Container Tracking — ONE (Ocean Network Express)-Owned Prefix
Track on ecomm.one-line.com — official ONE (Ocean Network Express) trackerONE (Ocean Network Express)'s tracker accepts the container number directly in the link — the checker below builds it for you.
ONE — Ocean Network Express — is the magenta-liveried 2017 merger of Japan’s three container lines: NYK, MOL and K Line. Overnight it became a top-six carrier operating from Singapore.
The merged fleet never repainted every box, so NYK- and K Line-registered codes still sail under the ONE flag, and the one-line.com tracker answers for all of them.
NYKU is registered to NYK Line, one of the three Japanese parents whose fleets merged into ONE in 2017 — the boxes track with ONE.
