The area code 602 is located in Phoenix, Arizona.
Area code 602 serves central Phoenix, Arizona, the state capital and seat of Maricopa County. It covers the city’s urban core, including downtown government buildings, major businesses, and cultural districts. Established in 1947 as Arizona’s original code under the North American Numbering Plan, 602 later shrank when 520 split off in the mid-1990s and 480/623 were added in 1999. Today, 602 is closely tied to central Phoenix, making it a strong signal of a city address and a downtown presence.
