Historical Timeline of Area Code 419
Area code 419 was created on January 1, 1947, as one of the original 86 area codes in the North American Numbering Plan.

Area code 419 was the last of Ohio's original four NPAs to receive any form of relief. The other three—216, 513, and 614—all underwent splits during the 1990s before overlays became the standard relief method. The decision to use an overlay for 419 rather than a split preserved the code's original 1947 boundaries.
Regulatory History
Area code 419 relief was managed by the Public Utilities Commission of Ohio (PUCO) with NANPA coordination. The PUCO oversees all Ohio area code decisions under FCC jurisdiction and has created overlays for six Ohio area code pairs: 330/234, 419/567, 740/220, 614/380, 937/326, and 513/283. Source: PUCO
