Area code 614 and 380 are the area codes in the North American Numbering Plan for Columbus, Ohio. Area code 614 is one of the original area codes assigned for Ohio in 1947, while area code 380 is an overlay code covering the same territory.
AT&T originally split Ohio into four numbering plan areas (NPAs), one for each quadrant of the state. Area code 614 was assigned to the southeastern quadrant, from Columbus to the Ohio River along the West Virginia border, stretching as far north as Steubenville.
Despite central Ohio's growth in the second half of the 20th century, this configuration remained in place for 51 years. In 1998, nearly all of the southern portion of the old 614 territory was split into the new area code 740. Ameritech, at that time the predominant incumbent local exchange carrier (ILEC), had proposed a split of 614 which generally would have seen Franklin, Delaware and Marion Counties retaining 614, with the rest of the Columbus suburbs following the rural portion of the old 614 into the new 740. A complaint before the Public Utilities Commission of Ohio (PUCO) claiming unequal treatment of the suburban counties was brought by Granville attorney J. Drew McFarland, later joined by the Village of Granville, Licking and Fairfield counties and others, wishing for an overlay area code. The PUCO instead reduced the 614 footprint to Columbus itself and Franklin County (with a subsequent appeal making a slight variation that allowed Dublin and Westerville to retain 614). The case represented the first time nationally that an ILEC's plan was substantially modified by consumer action.
As the numbering plan area 614 has been reduced to be all but synonymous with Columbus, it appears on some T-shirt designs that use 614 as an abbreviation or short form to identify the city.
In 2001, it was planned to overlay area code 614 with area code 380, in anticipation of exhaustion. However, the anticipated growth did not materialize and number pooling replaced the proposal. On January 14, 2015 the PUCO instructed the telecommunications industry to finally implement the new area code on February 27, 2016. Ten-digit local dialing has been required since January 30, 2016.
