The largest city served by these [[area code]]s is [[Toledo, Ohio|Toledo]] (and its suburbs of [[Holland, Ohio|Holland]], [[Maumee, Ohio|Maumee]], [[Northwood, Ohio|Northwood]], [[Oregon, Ohio|Oregon]], [[Ottawa Hills, Ohio|Ottawa Hills]], [[Perrysburg, Ohio|Perrysburg]], [[Rossford, Ohio|Rossford]], [[Sylvania, Ohio|Sylvania]], [[Swanton, Ohio|Swanton]], [[Waterville, Ohio|Waterville]], and [[Whitehouse, Ohio|Whitehouse]]).
==History== [[File:NANPs(Ohio)1952.jpg|thumb|The four original numbering plan areas of Ohio]] The [[original North American area codes|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 plan|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.<ref>{{cite news|first=Linda|last=Martz|title=Calling next door to require more thought|work=[[Mansfield News Journal]]|date=November 21, 2000|page=9A}}</ref><ref name=bryan>{{cite news|title=Mandatory 10-digit dialing will take effect Saturday|work=[[The Bryan Times]]|date=November 26, 2001|page=1}}</ref>
