If a 323 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.
The dialing plan is 1+10D for home-NPA local calls and 1+10D across codes.
Official projections put exhaust for the 213/323/738 complex at 3Q 2042.

FAQ
Why am I getting spam calls from 323 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 323 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 323 number from?
323 is assigned to Los Angeles:da 14 and surrounding areas of California in the Pacific time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 323 a toll-free number?
No. 323 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
Why do 213 and 323 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 213/323/738 complex shares one service area, and local calls are dialed with 10 digits.
Will 323 run out of numbers?
NANPA's current forecast projects exhaust in 3Q 2042 — decades of capacity remain.
