History of Area Code 602
Area code 602 is one of the original area codes created in 1947 under the North American Numbering Plan. At first, it covered the entire state of Arizona. Arizona kept a single statewide area code for decades as telephone use grew.
Area code 602 changed in 1995, when area code 520 split off to serve most of the state outside the Phoenix area. In 1999, the Phoenix region split again, and area code 480 was assigned to the East Valley while 623 was assigned to the West Valley. After that split, 602 remained mainly with central Phoenix.
