What is Region 9?

Region 9 commonly refers to a specific geographic division used by organizations, agencies, or government bodies to manage operations, resources, or services within a designated area. The meaning of Region 9 can vary depending on the context—for example, in the U.S. Environmental Protection Agency (EPA), Region 9 covers Arizona, California, Hawaii, Nevada, Pacific Islands, and Tribal Nations. It is important to verify the relevant organization to understand which areas and functions are included in their 'Region 9.'
