FAQ
Will 816 run out of numbers?
NANPA's current forecast projects exhaust in 3Q 2069 — decades of capacity remain.
Why am I getting spam calls from 816 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 816 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 816 number from?
816 is assigned to Kansas City and surrounding areas of Missouri in the Central time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 816 a toll-free number?
No. 816 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
