Toll-free phone numbers are ubiquitous contact channels for many businesses, both large and small, in the United States and Canada. Consumers can conveniently reach these businesses without having to pay for phone calls. These calls are routed, sometimes via multiple hops, between the home operator of the calling consumer and the service provider of the called business. Communication Service Providers (CSPs) involved in routing and transporting the calls need accurate data about each toll-free number in order to choose the most effective route and ensure an accurate delivery. NetNumber has partnered with SOMOS, the company of trusted, neutral numbering and registry administration services for the telecommunications industry and who maintains the authoritative SMS/800 TFN Registry. SOMOS has been designated by the FCC to administer this database. Customers using the North American Toll-Free Routing service get access to near real-time routing information for toll-free numbers that are listed in the North American Numbering Plan. Given a phone number, North American Toll-Free Routing will return a comprehensive set of related data elements. These data elements enable CSPs to determine the correct routing of voice calls to toll-free numbers ensuring accurate and error free calling.
