Polar Shipping
Polar Shipping (legal entity Polar Shipping Co., Inc.) is a niche operator headquartered in Anchorage, USA. Founded in 1981, the line has spent 45 years building out its container service network and today operates a fleet of 5 vessels under the SCAC code POLR. Total operated capacity stands near 3,500 TEU, placing the carrier among the recognised operators on its core trade lanes. The company holds intermodal equipment under 3 registered ISO 6346 owner prefixes, which appear on every box it owns or long-term leases.
Polar Shipping is most active on the following corridors: Alaska, Arctic. The line operates on a standalone basis and does not share vessel slots with other ocean carriers under a formal global alliance. Direct customer contact is available via +1 907 273 4000 or the carrier's web portal at polarshipping.com.
Polar Shipping 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. Polar Shipping 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 Polar Shipping.
POLUPOLRPOLN
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. Polar Shipping publishes its tracking page under the main polarshipping.com domain.
Polar Shipping corridor coverage
Polar Shipping concentrates its services on Alaska, Arctic. 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 Polar Shipping container
Tracking a Polar 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 (e.g. POLU) 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 Polar Shipping bill of lading. Visit polarshipping.com, 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 Polar Shipping hull. In the last case, the prefix still resolves to Polar Shipping as equipment owner but the schedule data lives with the operating carrier. Polar Shipping's customer service can normally cross-reference the booking and route you to the correct alliance partner. Reach the carrier on +1 907 273 4000 during European business hours.
