United States Minor Outlying Islands Port Codes
UN/LOCODE identifiers help carriers, forwarders and customs systems identify transport locations. The UM prefix identifies United States Minor Outlying Islands in the indexed code set.
City-Level and Terminal-Level Codes
A location code may identify a city, island, atoll or transport area, while a terminal or facility record can provide more operational detail. The code alone does not confirm berth availability or commercial service.
How to Verify a Port Code
Cross-check the location against UNECE resources and the Ecer Freight Port Codes directory. Booking parties should also confirm the current carrier acceptance and operating status.
Shipping from United States Minor Outlying Islands: Main Trade Lanes

Wake Island Supply Movement
Wake Island cargo is typically planned as specialized supply or project movement using a suitable Pacific service and confirmed onward logistics.
Johnston Atoll Resupply
Johnston Atoll movements are generally operational or project-based and require advance confirmation of access, equipment and cargo acceptance.
Midway Islands Project Cargo
Midway Islands cargo may involve conservation, infrastructure or government-related requirements, with handling arrangements confirmed case by case.
Pacific Feeder and Transshipment Planning
Because these locations do not present a conventional high-volume container network, shipments may require feeder, charter, breakbulk or transshipment solutions.
