Area code 380
Area code 380 covers Columbus, Ohio. We hold 1,449 allocated blocks for it across 16 rate centres, split 31% mobile, 33% landline and 36% VoIP.
The other area codes laid over 380
Area code 380 does not have Columbus to itself. 1 other code — 614 — serves the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
6145,644 blocks, 16 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 380 number and a 614 number from the same street can report different line types. Filtering Columbus by area code needs all 2 of them.
380 is not confined to Columbus itself: its blocks sit across 16 rate centres, named in the table below.
Ohio is split across 14 area codes — 740, 440, 937, 614, 513, 380 and others. By allocated blocks 380 is the 11th largest of them, holding 3% of the Ohio total.
Where 380 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Westervl is shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 380 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 380?
Area code 380 covers Columbus, Ohio. It is not the only code there: 614 is an overlay on the same rate centres, so a Columbus, Ohio number can start with any of them.
Is a 380 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 380 the split runs 31% mobile, 33% landline and 36% VoIP, so VoIP is the most likely single answer.
Which carriers hold 380 numbers?
The largest holders are Onvoy, AT&T Wireless, Verizon Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 380 numbers are there?
The code holds 1,449 allocated blocks in our copy of the numbering plan. A block is 1,000 or 10,000 consecutive numbers depending on how deeply it has been pooled, so 380 covers on the order of 1,449,000 possible numbers — most of which have never been issued to anyone.
