Somos, Inc.

Sole FCC-designated neutral administrator of the North American Toll-Free Number registry, operating as a regulated monopoly in toll-free number management.

Somos, Inc. serves as the neutral, FCC-designated administrator of the Toll-Free Number (TFN) registry in the United States and across the North American Numbering Plan (NANP). Originally established as SMS/800, Inc. and later rebranded to Somos, the company manages the lifecycle of toll-free numbers — including 800, 888, 877, 866, 855, 844, and 833 prefixes — from assignment and porting to routing and reclamation. Its SMS/800 database is the authoritative system of record for toll-free number management, used by telecommunications carriers, Responsible Organizations (RespOrgs), and enterprise customers. Somos plays a critical infrastructure role in business communications, enabling companies to acquire and manage toll-free numbers that are central to customer service, marketing campaigns, and brand identity. For marketers and advertisers, toll-free numbers are a key call-tracking and direct-response tool, making Somos an indirect but important enabler of performance marketing and call-based advertising measurement. Large enterprises, call centers, and media buyers rely on toll-free numbers to drive and measure inbound customer engagement from TV, radio, print, and digital campaigns. Beyond number administration, Somos has expanded its platform to include analytics, fraud prevention, and robocall mitigation tools — services increasingly relevant to the marketing and communications ecosystem. The company operates as a not-for-profit neutral administrator under contract with the FCC and industry stakeholders, positioning it as a trusted, regulated utility within the U.S. telecom infrastructure.
