Area code 614 was assigned to Ohio in 1947 as part of the first North American Numbering Plan, originally spanning a much larger stretch of southeastern Ohio. A November 1997 split that created area code 740 narrowed 614 to the Columbus area, where it now covers Franklin County along with portions of Delaware, Fairfield, and Union counties.
Columbus's economy spans several sectors that anchor the numbering plan area:
Beyond Columbus itself, the area extends to Dublin, Westerville, Pickerington, and Grove City. Continued growth led to the 2016 activation of area code 380 as an overlay on 614, which brought mandatory ten-digit local dialing to the region. Columbus is also home to Ohio State University, one of the largest university campuses in the country, reinforcing the area's higher-education presence alongside its financial, retail, and logistics base.
