Why use a toll-free number?

800, 888, 877, 866 — what's the difference?
Every toll-free prefix works exactly the same for the caller. 800 was the original. As demand grew, the FCC released 888, 877, 866, 855, 844, and 833 — each one identical in function.
Pick whichever prefix has the memorable digits or vanity pattern you want.
Popular toll-free prefixes explained
800 business phone number
The original toll-free prefix. An 800 business phone number is still the most recognized and trusted option for companies that want a national presence without tying themselves to one city.
888 area code
Released after 800 inventory ran low, 888 works identically and is widely accepted by consumers as a legitimate toll-free business line.
877 area code
The 877 area code is a standard toll-free prefix. Calls are free for customers, and the number can route to any phone or device your team uses.
866 area code
The 866 area code is another fully functional toll-free prefix. It gives your business the same nationwide reach and caller-paid-free experience as 800 numbers.
