RealNumber® is simple, secure way for your enterprise customer to verify their right to use a Toll-Free Number. RealNumber can help Originating Service Providers (OSPs) obtain A-Level Attestation through a scalable, authoritative solution. A subscriber of a Toll-Free Number can request a Verification Code from their Responsible Organization (Resp Org). The Resp Org can leverage RealNumber to generate the Verification Code and then provide it back to the Toll-Free Number subscriber. The subscriber then provides this code to their OSP who can verify its validity through a simple API call to the RealNumber database. Called parties can now trust that the number calling them is legitimate (see Figure 1 RealNumber How it works).
