235 area code — Birch Tree, MO geographic
235 is the area code for Birch Tree, Missouri, in service since March 24, 2024, Central time. It is part of the 235/573 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 235 number can be used from anywhere — the code marks where the number was assigned.
30 central-office prefixes are currently active in this code, spread across 11 code-holding carriers. Thousands-block pooling applies to 30 prefixes, so a single prefix can belong to several carriers. Its prefixes map to 18 distinct rate centers.
If a 235 call asks for money or personal data, treat the displayed number as unverified: hang up and reach the organization through its published number. Numbering data locates numbers, not callers.

FAQ
Why do 573 and 235 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 235/573 complex shares one service area, and local calls are dialed with 10 digits.
Will 235 run out of numbers?
NANPA's current forecast projects exhaust in 3Q 2063 — decades of capacity remain.
Why am I getting spam calls from 235 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 235 number does not prove the call originated there — see our guide to spotting spoofed calls.
