Permissive dialing of 602 continued across Arizona until October 22, 1995.

In 1993, Arizona was allocated a second area code, area code 520, for all of the state outside the Phoenix metropolitan area. īy the early 1990s, the need for a new area code could no longer be staved off. This meant that in-state toll and collect calls would require dialing the area code. BellCore, which at the time administered the assignment of area codes, denied the request and instead placed Arizona into the first phase of interchangeable dialing, in which central office codes with a middle digit of 0 or 1 were made available for use. However, as early as 1988, Mountain Bell, the incumbent local exchange carrier in the state, believed Arizona was growing too quickly to remain a single numbering plan area and requested a second area code for Arizona. ĭespite Arizona's explosive population growth in the second half of the 20th century, 602 remained Arizona's sole area code for 48 years. When the American Telephone and Telegraph Company (AT&T) created the first nationwide telephone numbering plan in 1947, Arizona was designated as a single numbering plan area and received a single area code, 602, of the original 86 area codes for routing telephone toll calls between states. The creation of the three-code overlay complex made ten-digit dialing mandatory across the Valley it was already required in 480. As a result, Arizona's Corporation Commission approved a plan in 2021 to reverse the 1999 split, and convert 480 and 623 into overlay codes for the entire Phoenix area in 2023. Metro Phoenix continued to be a single rate center after the split, so that calls between the three area codes were generally local calls.īy the early 2020s, 480 and 602 were facing exhaustion within the decade, but 623 continued to have hundreds of unassigned central office codes. In 1999, a second split created the 480 NPA in the East Valley, and area code 623 in the West Valley. In 1995, the state outside metropolitan Phoenix was split off with area code 520. Under pressure from population growth and new telecommunications services, the numbering plan area (NPA) was reduced twice in five years in the 1990s. state of Arizona.Īrea code 602 is the oldest area code in Arizona and was assigned in 1947 for the entire state.
