602 Area Code: Phoenix, Arizona

The 602 code is the original area code for Phoenix, Arizona, and now serves the city itself within the broader metropolitan numbering plan. Phoenix sits in the Salt River Valley, ringed by low desert ranges and watered by canal infrastructure that traces in part to pre-Columbian Hohokam earthworks. The city is the capital of Arizona and one of the largest in the country by population — a sprawling, low-rise metro that grew through twentieth-century air conditioning, postwar migration, and the steady absorption of nearby agricultural land into housing, commercial, and resort development.

Other Arizona cities — Glendale, Mesa, Tucson, and Yuma among them — appear frequently in the directory's records tied to 602 numbers. The overlap is a function of phone numbers traveling with their owners, address linkages crossing inter-city boundaries, and public-record patterns that don't follow area-code geography. Our records currently document 609 distinct prefixes within 602, which represents the directory's working subset; the underlying number of prefixes in service across the code is higher.

Demographically, Phoenix is defined more by its sheer scale than by any single distinguishing metric. The city's population places it near the top of US municipalities by headcount, and its overall demographic profile sits close to national norms — household income within reach of the US median, home values somewhat above. The median age skews a few years under the country's, reflecting the metro's continuing draw for younger working-age residents.
