The other area codes laid over 938
Area code 938 does not have Huntsville to itself. 1 other code — 256 — 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.
2566,391 blocks, 92 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 938 number and a 256 number from the same street can report different line types. Filtering Huntsville by area code needs all 2 of them.
938 is not confined to Huntsville itself: its blocks sit across 56 rate centres, named in the table below.

Where 938 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Rogersvl and Russellvl are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

AT&T Wireless alone holds 49% of every block in 938, which is unusually concentrated for an area code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 938 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 938?
Area code 938 covers Huntsville, Alabama. It is not the only code there: 256 is an overlay on the same rate centres, so a Huntsville, Alabama number can start with any of them.
Is a 938 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 938 the split runs 62% mobile, 16% landline and 22% VoIP, so mobile is the most likely single answer.
Which carriers hold 938 numbers?
The largest holders are AT&T Wireless, Onvoy, Onvoy Spectrum. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
