Area code 623


(c) Copyright 2010 ReversePhoneCheckc.com. All Rights Reserved

Area code 623 was created on 1st April 1999 for serving Arizona - State of United States of America. The particular code was created as a result in split of area code 480.

If any region starts lacking the combinations of phone number then the area is either split or overlaid -- and new code is assigned to newly created area. Unique codes are assigned to all regions so that to differentiate from where the call is coming.  

New area code was required for the State of Arizona when the code 623 was running out of available phone numbers because of the explosive demands for telephone lines. As a result areas located at the west side and the western half of the extreme north side turned into 623 area code. On the other hand the eastern Suburbs and the Phoenix area of Ahwatukee started using code 480 as telephone area code.

Standard Time Zone followed by the State of Arizona is Mountain Time Zone. The State of Arizona is currently served by following area codes:

  • Code 480 (created in 1999)
  • Code 602 (created in 1947)
