The U.S. state of Arizona is divided into three geographically distinct numbering plan areas (NPAs) which are identified by a total of five area codes, with one of the NPAs being configured as an overlay complex with two code.

602 was the original area code for Arizona, and was split in 1995 into 602, serving metropolitan Phoenix, and 520, serving the remainder of the state.[1] In 1999, 602 was split into 480, 602, and 623,[2] which were recombined in 2023.[3] 520 was split in 2001 to form area code 928.[4]
