FAQ

Where is a 320 number from?

320 is assigned to Saint Cloud and surrounding areas of Minnesota in the Central time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 320 a toll-free number?

No. 320 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.

Will 320 run out of numbers?

NANPA's current forecast projects exhaust in 2Q 2070 — decades of capacity remain.

Why am I getting spam calls from 320 numbers?

Scammers spoof recognizable area codes so calls look local or familiar. A displayed 320 number does not prove the call originated there — see our guide to spotting spoofed calls.
