Area codes in northwestern Ohio

The numbering plan areas (blue) and area codes of Ohio

**Area codes 419 and 567** are telephone [area codes](/source/Area_code) in the [North American Numbering Plan](/source/North_American_Numbering_Plan) (NANP) for [the northwestern part](/source/Northwest_Ohio) of the [U.S. state](/source/U.S._state) of [Ohio](/source/Ohio). The largest city served by these [area codes](/source/Area_code) is [Toledo](/source/Toledo%2C_Ohio) (and its suburbs of [Holland](/source/Holland%2C_Ohio), [Maumee](/source/Maumee%2C_Ohio), [Northwood](/source/Northwood%2C_Ohio), [Oregon](/source/Oregon%2C_Ohio), [Ottawa Hills](/source/Ottawa_Hills%2C_Ohio), [Perrysburg](/source/Perrysburg%2C_Ohio), [Rossford](/source/Rossford%2C_Ohio), [Sylvania](/source/Sylvania%2C_Ohio), [Swanton](/source/Swanton%2C_Ohio), [Waterville](/source/Waterville%2C_Ohio), and [Whitehouse](/source/Whitehouse%2C_Ohio)).

## History

The four original numbering plan areas of Ohio

The [first nationwide telephone numbering plan](/source/Original_North_American_area_codes) 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](/source/Overlay_plan) 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.[1][2]
