More than one of these codes covers 3 of the 15 counties in Arizona, and one county is covered by 4 of them. Each card counts the people inside that code's own boundary at the 2020 census. They add up to 7,150,693 against a census count of 7,151,502: although NANPA pairs some of these codes as overlays, the published boundaries divide the ground between them rather than repeat it.
How many phone prefixes does Arizona use?
The area codes in Arizona hold 3,019 assigned prefixes between them, listed under 81 distinct carrier names. A prefix is the three digits after the area code, and NANPA assigns each one to a single carrier.
