History of 623 Area Code

It was created on March 1, 1999, when the original area code 602 was split into three parts: 602, 480, and 623. The 623 area code covers the West Valley, including cities such as Glendale, Surprise, Buckeye, and Avondale. In 2023, the 623 area code was recombined with the other two area codes into an overlay complex that covers the entire Phoenix area.
