Area code 602

Area code 602 serves Arizona, including Phoenix (Mountain time). It has been in service since January 1, 1947 and shares its area with 480 and 623.

Numbers starting with 602 drew 2,323 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 1,104 complaints to the FCC since November 2023. The number on your screen can be faked, so a 602 number proves nothing about where a call came from.

Phone companies holding 602 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 55% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
