Background

When the first area code plan was introduced in 1947, the state was given area codes 216, 419, 513, and 614. In 1996, 330 and 937 were added as splits. In 1998, 440 and 740 were added as splits. Later, in 2000, 234 and 567 were added as overlays. In 2015, area code 740 will be overlaid with 220, relieving its rapid depletion.

Area code 380 will cover the Columbus/Central Ohio area, and 283 will cover the Cincinnati region when 513 is depleted.
