Beginning Oct. 17, all new phone numbers assigned within the 317 area code area will receive the new 463 area code.
This change will not affect existing phone numbers. However, mandatory 10-digit dialing will be necessary for local calls to be completed starting Sept. 17.
The same dialing procedure will apply to telephone numbers assigned to the new 463 area code.
• It will not be necessary to dial a “1” or a “0” when dialing your local and expanded local calls.
• Local calling areas and rates will not be affected by this change.
• Special services that use three-digit numbers, such as 911 and 411, as well as 1+ 10digit “long distance,” will not change.
• Other three-digit numbers that are currently available in your community or from your provider, such as 211, 311, 511, 611, 711 or 811, will not change.
