FAQ

Where is a 412 number from?

412 is assigned to Pittsburgh and surrounding areas of Pennsylvania in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 412 a toll-free number?

No. 412 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 878 and 412 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 412/878 complex shares one service area, and local calls are dialed with 10 digits.

Will 412 run out of numbers?

NANPA's current forecast projects exhaust in 2Q 2038 — decades of capacity remain.

Why am I getting spam calls from 412 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 412 number does not prove the call originated there — see our guide to spotting spoofed calls.
