About the 623 area code
Phoenix sits at the center of area code 623, an Arizona code that also serves Glendale, Peoria, and Buckeye, all on Mountain time.
The code was activated in 1999 as an overlay arising from area code 602's numbering area. Today 623 belongs to a three-code complex alongside 480 and 602, and because the codes occupy shared territory, completing a local call means dialing ten digits.
Dialing note: 623 is part of an overlay complex with 480, 602, so local calls in this area are dialed with all ten digits.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 10/08/2026.
