History of Area code 602

  • It is one of the original 86 area codes in NANP created by AT&T and the Bell System in 1947. Originally, it served the entire state of Arizona.
  • The need of area split happened due to Arizona’s explosive population growth that increased demand for telephone lines because of spread of fax machines, cell phones and dial-up Internet connections.
  • So, a new area code 520 introduced to cover outer portions of Maricopa County while most parts of Phoenix retained 602.
  • The implementation of 520 was a long-term solution but within only three years 602 became exhausted due to population growth and spread of telecommunication tools of the Valley of the Sun.
  • Therefore, a three-way geographic split became effective on April 1, 1999.
  • Area code 480 introduced to cover the eastern portions of valley and the other area code 623 came to cover west valley.
  • As a result of this split, the Phoenix became one of the few major cities in the nation to split between multiple area codes.
  • Most of Phoenix remained in 602, but a few areas served by 480 or 623.
