What is 602 Area Code?

The 602 area code is the original area code for Arizona, established in 1947. Over time, as the population and demand for phone numbers grew, it was split to create new area codes. 

Today, it serves the central part of the Phoenix metropolitan area, including downtown Phoenix, and is part of an overlay complex with area codes 480 and 623. This means all three area codes serve the same geographic region, and ten-digit dialing is mandatory.
