Where Is Area Code 602?
Area code 602 is a geographic telephone area code for Phoenix, Arizona, in the central part of the state. Phoenix is in the Mountain West region of the United States, and 602 primarily covers central Phoenix rather than the entire Phoenix metropolitan area.

History of Area Code 602
Area code 602 was assigned in 1947 as one of the original 86 North American area codes. It originally covered the entire state of Arizona, including Phoenix, Tucson, and northern Arizona.
On March 1, 1995, area code 520 split from 602 and took much of southern and eastern Arizona. On March 1, 1999, area codes 480 and 623 split from 602, leaving 602 focused on central Phoenix, 480 serving much of the East Valley, and 623 serving much of the West Valley. These changes were geographic splits rather than overlays, and they created more numbering capacity as Arizona's population and telephone use grew.
