855 area code — toll-free toll-free

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

Area code 855 is a toll-free code serving NANP AREA in the Eastern time zone. It has been in service since October 9, 2010. It is part of the 800/833/844/855/866/877/888 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 855 number can be used from anywhere — the code marks where the number was assigned.

855 was created from 800 in 2010.

As an Easily Recognizable Code (matching last digits), 855 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 855 for how these numbers behave in practice.

If a 855 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.
