FAQ
Why am I getting spam calls from 801 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 801 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 801 number from?
801 is assigned to Salt Lake City and surrounding areas of Utah in the Mountain time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 801 a toll-free number?
No. 801 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
