History

[edit]

The first nationwide telephone numbering plan of 1947 divided Ohio into four numbering plan areas (NPAs), one each for a quadrant of the state: 216, 419, 513, and 614. In 1996, 330 and 937 were added by splitting existing NPAs. In 1997, 440 and 740 were added in additional area code splits. In 2000, 234, and in 2002, 567 were added as overlays. In 2015, area code 740 was overlaid with 220, relieving its rapid depletion. In 2016, area code 614 was overlaid with 380 in the Columbus/Central Ohio area for the same reason. In 2020, 326 was added as an all services overlay for 937. Area code 283 was added as an overlay for 513 on April 28, 2023.[2][3] Area code 436 went into service on March 1, 2024, as an overlay of 440.[4]
