  • The former 602 area consists of most of the city of Phoenix, with the exception of far northern areas and Ahwatukee.
  • The former 480 area includes the East Valley, including Ahwatukee in the city of Phoenix and some communities in Pinal County such as San Tan Valley. Major cities include Mesa, Chandler, Gilbert, Scottsdale, and Tempe.
  • The former 623 area includes the West Valley. Major cities include Glendale, Surprise, Buckeye, and Avondale.
• Area code 520 serves Southern Arizona, including Tucson and its metropolitan area, Casa Grande, Nogales, and Sierra Vista.
• Area code 928 includes the remainder of the state, including Yuma, Kingman, Flagstaff, Prescott, the Arizona portion of the Navajo Nation, and Safford.
