Area code 937 is centred on Dayton, Ohio. We hold 5,767 allocated blocks for it across 123 rate centres, split 40% mobile, 50% landline and 10% VoIP.
The other area codes laid over 937
Area code 937 does not have Dayton to itself. 1 other code — 326 — 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.
326673 blocks, 56 rate centres, mostly VoIP
Each holds its own blocks and its own carrier mix, so a 937 number and a 326 number from the same street can report different line types. Filtering Dayton by area code needs all 2 of them.
937 is not confined to Dayton itself: its blocks sit across 123 rate centres, named in the table below.

Where 937 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Msbgwcrltn and Ylspgclftn are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

No carrier holds more than 10% of 937; the blocks are spread thin across many companies.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 937 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 937?
Area code 937 covers Dayton, Ohio. It is not the only code there: 326 is an overlay on the same rate centres, so a Dayton, Ohio number can start with any of them.
Is a 937 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 937 the split runs 40% mobile, 50% landline and 10% VoIP, so landline is the most likely single answer.
Which carriers hold 937 numbers?
The largest holders are Onvoy, Verizon Wireless, AT&T Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 937 numbers are there?
The code holds 5,767 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 937 covers on the order of 5,767,000 possible numbers — most of which have never been issued to anyone.
