How to track a Tsakos Shipping container

Tracking a Tsakos Shipping 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 is followed by six numeric digits and a single check digit. Blue Water Facts no longer publishes a per-carrier owner-prefix list (see /accuracy/ for why); confirm the operator via the carrier's own tracking portal or your bill of lading. Visit tenn.gr, 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 Tsakos Shipping hull. In the last case, the schedule data lives with the operating carrier, not the equipment owner. Tsakos Shipping's customer service can normally cross-reference the booking and route you to the correct alliance partner. Reach the carrier on +30 210 947 5300 during European business hours.
