FAQ
Is 324 a toll-free number?
No. 324 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 904 and 324 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 324/904 complex shares one service area, and local calls are dialed with 10 digits.
Will 324 run out of numbers?
NANPA's current forecast projects exhaust in 3Q 2057 — decades of capacity remain.
