A new area code will be activated in Ohio as the relief method for existing 937 NPA which serves the south western part of the state, the following towns and cities included: Dayton, Hillsboro, Marysville or Springfield. The new 326 area code was approved on May 23, 2018 by the Public Utilities Commission of Ohio and will serve the exact same geographic area covered today by area code 937. Local calls will be dialed using 10 or 11 digits when NPA 326 becomes active in 2020.
See official NANPA planning letter and map of the new overlay complex 937/326 (PDF document).
