877 area code — toll-free toll-free

Data: NANPA public reports, current as of July 28, 2026.

If a call shows area code 877, the number was issued in NANP AREA — a code active since 1998, on Eastern time. Together with 800, 888, 866, 855, 844, 833 it forms the 800/833/844/855/866/877/888 overlay. Because of number portability and VoIP, the area code tells you where the number was issued, not where the caller is right now.

Its parent code is 800, which it left in 1998.

As an Easily Recognizable Code (matching last digits), 877 is reserved for toll-free service: the called business pays for the call, and the number works across the US, Canada and much of the Caribbean. Toll-free numbers are assigned individually from the SMS/800 registry run by Somos, not in carrier prefix blocks — which is why no rate-center table exists for this code. See the toll-free profile of 877 for how these numbers behave in practice.

If a 877 call asks for money or personal data, treat the displayed number as unverified: hang up and reach the organization through its published number. Numbering data locates numbers, not callers.

FAQ

Why am I getting spam calls from 877 numbers?

Scammers spoof real area codes so calls look legitimate. A displayed 877 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 877 number from?

877 is assigned to NANP AREA in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 877 a toll-free number?

Yes — 877 is one of the seven US toll-free codes (800, 833, 844, 855, 866, 877, 888): the called business pays for the call.

Why do 800 and 877 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 800/833/844/855/866/877/888 complex shares one service area, and local calls are dialed with 10 digits.
