319 Area Code Split

Prior to the December 2, 2001, mandatory dialing date, businesses that use specialized communications equipment (often called PBX equipment), electronic telephone sets, auto-dial systems or multi-line key systems must verify that their telephone equipment is able to reach the new 563 area code.

New area codes being assigned across the country, like Iowa's new 563 area code, use a different format than area codes in the past, which had a "1" or a "0" as the middle digit. Some telephone equipment used by businesses will not recognize the new area code until that equipment has been reprogrammed or upgraded.

Beginning March 25, 2001, businesses can test their telephone equipment to determine if it recognizes the 563 area code by calling the following test number: 563-324-0563. If a call to the test number does not go through, contact your equipment provider. If your equipment is not the cause of the problem, please call KCTC at 319-656-3668

These prefixes will move to the new 563 area code:
