Piketon, a village in Pike County, Ohio, United States, along the Scioto River. The village is best known for the uranium enrichment plant located there (one of only three such plants in the United States). The population was 2,181 at the 2010 census. Originally called Jefferson, it was the county seat of Pike County 1815–1845, when it was decided by James Emmitt, a wealthy local entrepreneur, to move the county seat to Waverly due to its closer proximity to the then new Ohio & Erie Canal. It is the location of the Pike County Fairgrounds, and is served by the Scioto Valley School District. ^source

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
