Area code 315 is a telephone area code in upstate New York. It stretches from the eastern border of Monroe County to Little Falls north to the Canadian border east to Massena and south to near Cortland.

New York State regulators announced that area code 315 was initially projected to become "exhausted" during the third quarter of 2010. The New York State Public Service Commission is weighing options including: an overlay area code or a split into two area codes. Future border splits may include a north/south arrangement that would split Oswego County and parts north to a separate area code from Syracuse or a split of east/west that would split Oswego Onondaga and western counties from those to the east of them. Regulators met to discuss how best to create an additional area code in the 315 area code region but because of economic conditions assignable numbers will not run out in the third quarter of 2010 as predicted. The predicted year has now been extended until the first quarter of 2013.1 Contents 1 Areas served 1.1 Counties 1.2 Cities and towns 2 See also 3 External links 4 References Areas served Counties Cayuga Chenango Cortland Fulton Hamilton Herkimer Jefferson Lewis Madison Oneida Onondaga Ontario Oswego Otsego Saint Lawrence Seneca Wayne and Yates Cities and towns Adams Center Adams Alder Creek Alexandria Bay Altmar Alton Antwerp Apulia Station Auburn Aurora Ava Baldwinsville Barneveld Beaver Falls Belleville Bernhards Bay Black River Blossvale Boonville Bouckville Branchport Brantingham Brasher Falls Brewerton Bridgeport Bridgewater Brier Hill Brookfield Brownville Calcium Camden Camillus Canastota Canton Cape Vincent Carthage Cassville Castorland Cato Cayuga Cazenovia Central Square Chadwicks Chase Mills Chaumont Chippewa Bay Chittenango Cicero Clark Mills Clay Clayton Clayville Cleveland Clifton Springs Clinton Clockville Clyde Cold Brook Colton Constableville Constantia Copenhagen Cranberry Lake Croghan De Kalb Junction De Peyster De Ruyter Deansboro Deer River Deferiet Delphi Falls Dewitt Denmark Depauville Dexter Dolgeville Dresden Durhamville Eagle Bay Earlville East Syracuse East Williamson Eaton Edwards Elbridge Ellisburg Erieville Evans Mills Fabius Fair Haven Fayette Fayetteville Felts Mills Fine Fishers Landing Forestport Fort Drum Frankfort Franklin Springs Fulton Geneva Genoa Georgetown Glenfield Gouverneur Great Bend Greig Hailesboro Hamilton Hammond Hannawa Falls Hannibal Harrisville Hastings Helena Henderson Harbor Henderson Herkimer Hermon Heuvelton Hinckley Hoffmeister Holland Patent Hubbardsville Ilion Inlet Jamesville Jordan Jordanville Keuka Park King Ferry Kirkville Knoxboro La Fargeville La Fayette Lacona Lawrenceville Lee Center Leonardsville Limerick Lisbon Little Falls Liverpool Locke Lorraine Lowville Lycoming Lyons Falls Lyons Macedon Madison Madrid Mallory Manlius Mannsville Maple View Marcellus Marcy Marietta Marion Martinsburg Martville Massena Mc Connellsville Memphis Meridian Mexico Middleville Minetto Minoa Mohawk Montezuma Moravia Morristown Morrisville Mottville Munnsville Natural Bridge Nedrow New Hartford New Haven New Woodstock New York Mills Newark Newport Newton Falls Nicholville Norfolk North Bay North Brookfield North Lawrence North Pitcher North Rose Norwood Oaks Corners Ogdensburg Old Forge Oneida Ontario Center Ontario Oriskany Oriskany Falls Orwell Oswegatchie Oswego Oxbow Palmyra Parish Parishville Penn Yan Pennellville Peterboro Phelps Philadelphia Phoenix Pierrepont Manor Plainville Plessis Poland Pompey Poplar Ridge Port Byron Port Gibson Port Leyden Potsdam Preble Prospect Pulaski Pultneyville Pyrites Raquette Lake Raymondville Red Creek Redfield Redwood Remsen Rensselaer Falls Richfield Springs Richland Richville Rodman Rome Romulus Rooseveltown Rose Russell Sackets Harbor Salisbury Center Sandy Creek Sangerfield Sauquoit Savannah Schuyler Lake Scipio Center Seneca Castle Seneca Falls Sherrill Skaneateles Falls Skaneateles Sodus Sodus Point Solsville Solvay South Butler South Colton South Otselic Springfield Center Star Lake Sterling Stittville Stratford Sylvan Beach Syracuse Taberg Thendara Theresa Thousand Island Park Three Mile Bay Tully Turin Union Springs Utica Van Hornesville Vernon Center Vernon Verona Beach Verona Waddington Walworth Wampsville Wanakena Warners Washington Mills Waterloo Watertown Waterville Weedsport Wellesley Island West Eaton West Edmeston West Leyden West Monroe West Stockholm West Winfield Westdale Westernville Westmoreland Whitesboro Williamson Williamstown Winthrop Wolcott Woodgate and Yorkville See also List of New York area codes List of NANP area codes North American Numbering Plan External links NANPA Area Code Map of New York List of exchanges from AreaCodeDownload.com 315 Area Code New York area codes: 212 315 347 516 518 585 607 631 646 716 718 845 914 917 North: 613/343 West: 585 area code 315 East: 518 South: 607 Ontario area codes: 226 249 289 343 365 416 519 613 647 705 807 905 References http://www.askpsc.com/askpsc/page/PageActionrenderPageById&PageIde8f48505629063f56fa165a2c0839a4b
