Area code 937 is a telephone area code in the North American Numbering Plan (NANP) assigned to a numbering plan area (NPA) that encompasses much of the southwestern part of the U.S. state of Ohio, including Dayton and Springfield. It was established in September 1996, after a split from area code 513.
Area code 937 serves Dayton, its metropolitan area, public (non-Defense Switched Network) communications at Wright-Patterson Air Force Base, and most of southwest Ohio north and east of the Cincinnati metropolitan area.
Communities served which have a 2019 population greater than 10,000 or are county seats, include Beavercreek, Bellefontaine, Centerville, Clayton, Dayton, Eaton, Englewood, Fairborn, Franklin, Georgetown, Greenville, Hillsboro, Huber Heights, Kettering, Marysville, Miamisburg, Piqua, Riverside, Sidney, Springboro, Springfield, Tipp City, Trotwood, Troy, Urbana, Vandalia, West Carrollton, West Union, Wilmington and Xenia.
Counties covered include all or parts of Adams, Brown, Champaign, Clark, Clermont, Clinton, Darke, Greene, Hardin, Highland, Logan, Madison, Miami, Montgomery, Preble, Ross, Scioto, Shelby, Union and Warren.
Area code 937 was split from area code 513 on September 28, 1996. At the time, literature promoting the new area code took advantage of the fact that the numbers 937 spell out "YES" on a standard telephone keypad.
Area code 937 is expected to exhaust all numbers by the third quarter of 2020, so area code 326 (which spells out "DAO" as in "DAyton, Ohio") is scheduled to overlay the 937 area. Since early August 2019, customers are encouraged to use ten digits for local calls within the area code. Come early February 2020, traditional seven-digit local calling will be extinct, and customers who attempt such calls will hear a recorded reminder message. On March 8, 2020, the 326 area code will take effect.
