Contiguous Zone - U.S.-Affiliated Pacifc Islands

Published by Pacific Islands Ocean Observing System (PacIOOS) | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2016-01-25T00:00:00.000+00:00
These boundaries represent the contiguous zone for U.S.-affiliated Pacific Islands, including Hawaii, American Samoa, the Commonwealth of the Northern Mariana Islands (CNMI), Guam, as well as the U.S. Minor Outlying Islands of Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Palmyra Atoll, and Wake Island. The contiguous zone is a band of water extending from the outer edge of the territorial sea to up to 24 nautical miles from the coastal baseline (usually the mean low-water mark), within which a state can exert limited control for the purpose of preventing or punishing "infringement of its customs, fiscal, immigration or sanitary laws and regulations within its territory or territorial sea". However, unlike the Territorial Sea there is no standard rule for resolving such conflicts, and the states in question must negotiate their own compromise.
