ALL CUSTOMERS WITH INDIANA 317 AREA CODE MUST DIAL
AREA CODE + TELEPHONE NUMBER
FOR ALL LOCAL CALLS BEGINNING October 15, 2016
To ensure a continuing supply of telephone numbers, the new 463 area code will be added to the area served by 317. This is known as an area code overlay. Get ready to change the way you dial your local calls!
What is the new dialing procedure?
To complete local calls, the new dialing procedure requires callers to dial area code + telephone number. This means that all calls in the 317 area code that are currently dialed with seven digits will need to be dialed using area code + telephone number.
When will the change be mandatory?
Beginning October 15, 2016, you must use the new dialing procedures, as described above for all calls. After this date, if you do not use the new dialing procedures, your calls will not be completed and a recording will instruct you to hang up and dial again.
However, all customers should begin using the new dialing procedure before October 15, 2016.
Beginning November 15, 2016, new telephone lines or services may be assigned numbers using the new 463 area code.
Who will be affected?
The 317 area code generally covers the region of Indianapolis and most of its suburbs. The new 463 area code will serve the same geographic area currently served by the existing 317 area code
Why is the change necessary?
To ensure a continuing supply of telephone numbers, the new 463 area code will be added to the area served by 317. Since the two area codes will now serve the same geographic region, the area code must be used when dialing any telephone number, including calls within the same area code.
What will you need to do?
In addition to changing your dialing procedures, all services, automatic dialing equipment, or other types of equipment that are programmed with a 7-digit number will need to be reprogrammed to use the new dialing procedures. Some examples are life safety systems, PBXs, fax machines, Internet dial-up numbers, alarm and security systems, gates, speed dialers, call forwarding settings, voicemail services, etc. You may also want to check your website, business stationery, printed checks, contact information, pet ID tags, or advertising materials to ensure the area code is included. Important safety and security equipment, such as medical alert devices, and alarm and security systems must be programed to use 10-digit dialing. Many systems operate on 10-digit dialing by default but some older equipment may still use 7-digits. Please contact your medical alert or security provider if you don’t know whether your equipment needs to be reprogrammed to accommodate the upcoming change to 10-digit dialing.
What will remain the same?
