What Are Toll-Free Telephone Numbers?
A toll-free telephone number is a phone number that customers can call without paying call charges. The business receiving the call covers the cost of the inbound call, making it easier for customers to reach sales, support, reservations, and service teams.

International toll-free numbers let callers in other countries reach you free of charge, either through an International Toll-Free Service (ITFS) number routed to your team anywhere in the world, or a Universal International Freephone Number (UIFN, +800) that works across multiple participating countries.
A virtual toll-free number isn't tied to a physical phone line. With modern cloud communications, it can be routed to web browsers, mobile phones, desk phones, contact centers, SIP connections, and distributed teams worldwide, without local hardware or offices.
