Where is Area Code 602 located?

Known as the “Valley of the Sun,” Phoenix is the fifth most populated city in the United States, and it’s packed with beautiful desert landscapes, rich history, and vibrant culture.

602 Area Code Time Zone
The 602 area code follows the Mountain Standard Time (MST), which is 7 hours behind Coordinated Universal Time (UTC-7). Interestingly, Arizona does not observe daylight saving time, so while other states “spring forward” or “fall back,” the time in the 602 area code remains unchanged throughout the year.
History of 602 Area Code
The 602 area code has a rich history. It was one of the original 86 area codes established by AT&T in 1947. Initially, it covered the entire state of Arizona until it was split in 1995 due to rising population and demand for telephone lines. The 520 area code was created for Tucson and Southern Arizona, and later in 1999, Phoenix was split again to create the 480 and 623 area codes. However, 602 still remains the primary area code for downtown Phoenix.
