Effective March 12, 2016, you should begin using the new dialing procedures whenever you place a call from the 315 area code. If you forget and dial just seven digits, your call will still be completed.
Required Dialing Procedures
Beginning February 11, 2017, 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.
New Lines & Services
Beginning March 11, 2017, new telephone lines or services may be assigned numbers using the new 680 area code. All calls made within and between area codes 315 and 680 must be placed using the 10-digit telephone number (315 or 680 plus the 7-digit telephone number).
