Area code 235
Area code 235 is centred on Birch Tree, Missouri. We hold 293 allocated blocks for it across 21 rate centres, split 65% mobile, 3% landline and 32% VoIP.
The other area codes laid over 235
Area code 235 does not have Birch Tree to itself. 1 other code — 573 — 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.
5736,496 blocks, 216 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 235 number and a 573 number from the same street can report different line types. Filtering Birch Tree by area code needs all 2 of them.
235 is not confined to Birch Tree itself: its blocks sit across 21 rate centres, named in the table below.

Where 235 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Jeffersncy and St James 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 51% of every block in 235, 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 235 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 235?
Area code 235 covers Birch Tree, Missouri. It is not the only code there: 573 is an overlay on the same rate centres, so a Birch Tree, Missouri number can start with any of them.
Is a 235 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 235 the split runs 65% mobile, 3% landline and 32% VoIP, so mobile is the most likely single answer.
Which carriers hold 235 numbers?
The largest holders are AT&T Wireless, Onvoy, T-Mobile Usa, Inc.. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 235 numbers are there?
The code holds 293 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 235 covers on the order of 293,000 possible numbers — most of which have never been issued to anyone.
