Find any 602- phone number in Arizona
The 602 area code is a telephone numbering plan code in the North American Numbering Plan (NANP) for the state of Arizona. It was one of the original area codes established in 1947 and originally covered the entire state. However, in 1995, its coverage area was split due to the rapid growth in population and telephone use. The 602 area code now covers the Phoenix metropolitan area, including the cities of Tempe, Glendale, Peoria, and Scottsdale.
The NANP is a system that allows all telephone services to be standardized across the continent, enabling callers to make long-distance calls with only seven-digit numbers. The numbering codes are composed of three elements: a three-digit area code, a three-digit central office code, and a four-digit line number. The North American Numbering Plan, which is administered by the Federal Communications Commission (FCC), provides a smooth and efficient flow of telephone services and is the basis for all digital communications in the U.S., Canada, and seventeen other countries and territories.
