FAQ
Where is a 380 number from?
380 is assigned to Columbus and surrounding areas of Ohio in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 380 a toll-free number?
No. 380 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
Why do 614 and 380 cover the same place?
They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 380/614 complex shares one service area, and local calls are dialed with 10 digits.
