OCONUS

What does OCONUS stand for?

Outside of contiguous United States

OCONUS is an acronym that signifies “outside of contiguous United States” or “outside of conterminous United States”. It’s used to describe places like Alaska and Hawaii, which aren’t attached to other U.S. states, and any place in the rest of the world.

This term is commonly used by organizations like the U.S. Department of Defense and the National Weather Service. You might also see it online where it’s used to show shipping costs and options for items that need to be sent to places that aren’t part of the contiguous United States.

Sometimes, OCONUS might also mean “outside of continental United States”. In this case, it specifically refers to Hawaii since it’s not part of North America like Alaska, and also includes any place outside of the U.S. mainland. The term OCONUS actually comes from the more commonly used acronym CONUS, which stands for the contiguous or continental United States.
