Area codes 419 and 567 are telephone area codes in the North American Numbering Plan (NANP) for the northwestern part of the U.S. state of Ohio. The largest city served by these area codes is Toledo (and its suburbs of Holland, Maumee, Northwood, Oregon, Ottawa Hills, Perrysburg, Rossford, Sylvania, Swanton, Waterville, and Whitehouse).
The first nationwide telephone numbering plan of 1947 divided Ohio into four numbering plan areas (NPAs), roughly forming a quadrant layout for telecommunication services in the state.
Area code 419 was assigned to the northwest quadrant of the state. The overlay area code 567 was created on January 1, 2002. Despite the presence of Toledo, the state's fourth-largest city, 419 had been the last of Ohio's original four numbering plan areas, and one of the few original NPAs not covering an entire state, that had never been split or overlaid. However, because of the choice of an overlay, it is one of the few original NPAs not covering an entire state that still has its original boundaries.
Other municipalities served by these area codes include Ada, Ashland, Bellevue, Bluffton, Bowling Green, Bryan, Bucyrus, Celina, Clyde, Crestline, Defiance, Delphos, Edgerton, Edison, Edon, Elmore, Findlay, Fostoria, Fremont, Galion, Genoa, Kenton, Lima, Mansfield, Montpelier, Mount Gilead, Napoleon, Norwalk, Oak Harbor, Port Clinton, Sandusky, Shelby, St. Marys, Tiffin, Upper Sandusky, Van Wert, Wapakoneta, Wauseon, Willard, and Woodville. Other areas served include the Lake Erie Islands north of Port Clinton and west of Sandusky.

In telecommunications, an area code overlay complex is a telephone numbering plan that assigns multiple area codes to a geographic numbering plan area (NPA). Area code overlays are implemented in territories of the North American Numbering Plan (NANP) to mitigate exhaustion of central office codes in growth areas. The method has been in use since 1992, and has been the preferred and exclusive method of relief since 2007.
Ten-digit dialing is a telephone dialing procedure in the countries and territories that are members of the North American Numbering Plan (NANP). It is the practice of including the area code of a telephone number when dialing to initiate a telephone call. When necessary, the ten-digit number may be prefixed with the trunk code 1, which is referred to as 1+10-digit dialing or national format.
Area codes 614 and 380 are telephone area codes in the North American Numbering Plan (NANP) for all or part of four counties in central Ohio, surrounding and including the state capital of Columbus.
