480 Area Code: Mesa, Arizona

Mesa anchors the 480 area code, which covers a wide band of the East Valley in metropolitan Phoenix. Mesa itself is one of the largest cities in Arizona, sitting on a plateau-like rise above the Salt River and laid out on a famously broad street grid first surveyed in the late nineteenth century. The 480 designation, part of the North American Numbering Plan, was carved from the Phoenix region's older numbering as the metro expanded in the 1990s and now reaches across Mesa, Tempe, Scottsdale, Chandler, and adjacent suburbs that grew up alongside them.

Other Arizona cities — Glendale, Phoenix, Tucson, and Yuma — recur in the directory's records linked to 480 numbers. They are not part of the 480 geographic footprint; the overlap shows up because phones, addresses, and registrations cross intra-state boundaries freely, and the public-record sources that feed the directory don't filter on area-code geography. We currently document 661 distinct prefixes within 480, a working subset of the live total rather than a comprehensive count of every prefix in service.

Home values in Mesa run a touch above the US median, an indicator of the broader Phoenix-metro housing market that has reset price levels across the East Valley over the past decade. Household income tracks roughly with the national figure, the median age is a few years younger than the country at large, and the population places Mesa among the higher-population suburbs anywhere in the country — large enough to function more like a co-equal city than an outlying community.
