Toledo/Northwest Ohio
One of Ohio's four original 1947 area codes, serving northwestern Ohio including Toledo, Lima, Sandusky and Findlay. It was the last of the four originals to remain unsplit/unoverlaid until 2002.
Status, dates and counts are read from NumberResearch (NANPA / CNAC / FCC records). Assignment records show initial assignees, not the carrier serving a number today.
Where 419 is
Northwestern Ohio (Toledo metro and north-central Ohio).
Communities served wholly or partly by 419:
Representative; includes Toledo suburbs (Maumee, Sylvania, Perrysburg) and Lake Erie Islands north of Port Clinton.
How it relates to other codes
The codes 419 was split from, spawned, or shares its area with. A split divides the map and changes some numbers; an overlay shares the same ground and changes none — what's the difference?
