This map of nearly 4,900 ZIP code areas can be used to determine the eligibility of applicants for programs designed for Appalachian residents based on a mailing address. ZIP Code areas may cross state and county boundaries and therefore some in Appalachia may extend beyond ARC’s service area. The map and data were developed using the Census Bureau’s 2020 ZIP Code Tabulation Area (ZCTA)-to-County Relationship File to approximate U.S. Postal Service ZIP Code service areas.
