North American Area code 740 is a telephone area code serving southeastern and central Ohio. (Columbus and rate centers in Franklin County use the 614 area code.) 740 is the area code in the Ohio cities of Athens, Belpre, Chillicothe, Circleville, Coshocton, Delaware, Gallipolis, Heath, Ironton, Jackson, Lancaster, Laurelville, Logan, Marietta, Marion, Mount Vernon, Nelsonville, Newark, Portsmouth, Rockbridge, Steubenville, Washington Court House, Zanesville, Shadyside and surrounding areas. Area code 740 was established on December 6, 1997; it split from area code 614 in 1998. On November 7th 2013 it was announced that the 740 area code would run out of numbers sometime in 2015. The Public Utilities Commission of Ohio chose to remedy the situation by implementing an overlay of a new 220 area code beginning in early 2015. Customers living in the area will be required to dial the full ten digit telephone number for local calls. ^source
