Area Code Overlay Approved for the New York 315 Area Code

An overlay is the addition of another area code (680) to the same geographic region as an existing area code (315). An overlay does not require customers to change their existing area code.

The 315 area code covers the west-central portion of New York serving communities such as Syracuse, Utica and Watertown.  The new 680 area code will serve the same geographic area currently served by the existing 315 area code.

To complete calls within the 315 area code region, the new dialing procedure requires callers to dial area code + telephone number. This means that all calls in the 315 area code that are currently dialed with seven digits will need to be dialed using ten digits, that is, the area code + telephone number. The same dialing procedure will apply to telephone numbers assigned to the new 680 area code.

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.

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.

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).

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 business stationery or advertising materials to ensure the area code is included.

• Your telephone number, including current area code, will not change.

• The price of a call, coverage area, or other rates and services will not change due to the overlay.

• What is a local call now will remain a local call regardless of the number of digits dialed.

• You will continue to dial 1+ area code + telephone number for all calls to other area codes (outside of 315 and 680).

• You can still dial just three digits to reach 911.

• If 211, 311, 411, 511, 611, 711 or 811 are currently available in your community you will still dial these codes with just three digits.
