In 1947 when area codes were first created in the country, Arizona had just one area code 602 serving the whole state. With population increase and the expansion in the number of phone subscribers, the state now has five area codes. Knowing the area codes that serve the state help residents identify local calls and identify the part of the state where those calls originate. They can also identify unknown callers with reverse phone lookup services.
The five area codes serving the state of Arizona are:
| 602 - Location | |||
| 480 - Location | |||
| 520 - Location | |||
| 623 - Location | |||
| 928 - Location | |||
Who Controls Arizona Area Codes?
The final decision on the specific areas assigned area codes by the NANPA rests with the Arizona Corporation Commission (ACC). The ACC will decide if there will be a split (dividing a region into two with one part retaining the old area code while the other part of the region gets to use the newly assigned area code) or an overlay (the new area code will be introduced and used alongside the existing one for the same region).
