659 area code — Birmingham, AL geographic
If a call shows area code 659, the number was issued in the Birmingham area — a code active since 2019, on Central time. Together with 205 it forms the 205/659 overlay. Because of number portability and VoIP, the area code tells you where the number was issued, not where the caller is right now.
NANPA lists 171 active NXX prefixes in 659, assigned to 29 carriers. 171 of those prefixes are pooled — shared between carriers in thousands-number blocks. The code spans 64 rate centers (billing localities).
Official projections put exhaust for the 205/659 complex at 1Q 2066.
Its parent code is 205, which it left in 2019.
The dialing plan is 10D for home-NPA local calls and 10D across codes.
To check where a specific 659 number was issued, look up its six-digit prefix; to check who is actually calling, ignore the display and verify through an official callback number — caller ID is assertable and routinely spoofed.

FAQ
Why do 205 and 659 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 205/659 complex shares one service area, and local calls are dialed with 10 digits.
Will 659 run out of numbers?
NANPA's current forecast projects exhaust in 1Q 2066 — decades of capacity remain.
Why am I getting spam calls from 659 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 659 number does not prove the call originated there — see our guide to spotting spoofed calls.
