What is the 602 Area Code? Time Zone and Location
- Area code 602 is located in central Arizona, serving the core of the Phoenix metropolitan area, primarily covering Phoenix and nearby cities such as Glendale, Scottsdale, Tempe, and Paradise Valley within Maricopa County.
- It has two overlays (480 and 623) that serve the same geographic area, and in 2023 the Arizona Corporation Commission implemented a boundary elimination overlay across all three, requiring mandatory 10-digit dialing throughout the Phoenix metro.
- Major cities covered include Phoenix, Mesa, Chandler, Scottsdale, and Tempe.
- The 602 area code is located in the Mountain Standard Time (MST) zone — Arizona does not observe Daylight Saving Time, so it remains on MST year-round at UTC−7.
- Area code 602 was put into service in 1947 and was one of the original 86 area codes, originally serving the entire state of Arizona.
- 602 was split in 1995 creating area code 520, again in 1999 to create area code 623, and again in 1999 to create area code 480, with 602 remaining focused on central Phoenix.
- 10-digit dialing mandatory throughout the Phoenix metro area.
