Area code 480 serves the East Valley region of the Phoenix metropolitan area in Arizona, including cities such as Mesa, Chandler, Scottsdale, Tempe, and Gilbert. Created in 1999 from a split with 602, it helped accommodate the rapid population growth of the area. In 2023, area codes 480, 602, and 623 became part of an overlay complex, requiring ten-digit dialing. The 480 region is known for its suburban development, high-tech industries, and vibrant desert lifestyle. Area code 480 has become emblematic of the Phoenix area’s expansion and transformation, representing both affluence and innovation in Arizona’s fastest-growing corridor.
