Mandatory 10-Digit Dialing Begins February 11th for 315 Area Code

ALBANY — The New York State Public Service Commission (Commission) today announced that beginning February 11, 2017, residential, business and wireless consumers within the existing 315 area code in central New York will have to dial 10 digits when making a telephone call. The additional dialing is required as a result of the introduction of the new 680 area code which will take effect in March.

The creation of the new 680 area code allows telephone companies to accommodate the increasing need for telephone numbers in central New York, and also accommodates future telephone number demand, the results of a thriving telecommunications market in central New York.

To ensure a continuing supply of telephone numbers in the west-central portion of New York, the Commission in mid-2015 approved an area code overlay for the area served by 315.  The new area code will be superimposed over the same geographical area as the 315 area code.  The 315 area code is located within all or part of 18 counties in central New York, including: Cayuga, Chenango, Cortland, Fulton, Hamilton, Herkimer, Jefferson, Lewis, Madison, Oneida, Onondaga, Ontario, Oswego, Otsego, St. Lawrence, Seneca, Wayne, and Yates.

The area code overlay requires consumers to dial 10 digits (area code + 7 digit local telephone number) in the 315/680 area or 1+10 digits for calls to other area code regions.  To allow consumers time to adjust to the new dialing pattern, a permissive dialing period has been in place since March 12, 2016.  However, beginning February 11, 2017, the mandatory dialing period begins, when all calls within and between 315/680 must be placed using the 10-digit telephone number (315 or 680 plus the 7-digit local telephone number).  Under both the permissive and mandatory dialing schemes, calls to other area codes must still be dialed as 1+ 10 digits.

Important facts that consumers and businesses need to know about the upcoming 680 area code overlay are:

  • Current telephone numbers, including current area code, will not change.
  • Beginning February 11, 2017, all calls within and between 315/680 must be dialed with the area code plus the 7-digit local telephone number (“ten-digit dialing”).
  • Consumers will continue to dial 1+ area code + telephone number for all calls to other area codes.
  • What is a local call now will continue to remain a local call.
  • The price of a call, and the price of other telephone services, will not change due to the new overlay area code.
  • Calls to reach 911 Emergency Service will remain three digits.
  • If 211, 311, 411, 511, 611, 711 or 811 services are currently available in the community, consumers will still dial these codes with just three digits.

Customers should identify their telephone number as a ten-digit number (area code + 7-digit local telephone number) when giving the number to friends, family, business associates and business customers, etc.

Customers should ensure that all services, automatic dialing equipment, applications, software, or other types of equipment recognize the new 680 area code as a valid area code.  Some examples are: life safety systems, fax machines, Internet dial-up numbers, alarm and security systems, gates, speed dialers, mobile phone contact lists, call forwarding settings, voicemail services, and similar functions.  Business stationery, advertising materials, personal checks, and personal or pet ID tags should include the area code.  All calls within the 315/680 area must be programmed to dial using 10-digits and the digit prefix “1” must be included for all calls to other area codes.
