Numeracle filed comments in the WC Docket 17-97 reviewing the effectiveness of the STIR/SHAKEN framework and recommending that caller authentication policy be paired with structured identity governance controls. The filing was submitted to the Federal Communications Commission as part of the Call Authentication Trust Anchor proceeding.

The comments support the technical foundation of STIR/SHAKEN but argue that authentication signaling alone does not solve the consumer trust problem unless identity proofs are carried across the entire communication path. Numeracle emphasizes that providers should operationalize Know Your Customer–anchored onboarding, number right-to-use validation, and traffic risk assessment as core operational processes. The filing further advocates broader deployment of Rich Call Data and BCID-style verified display mechanisms so that authenticated identity information survives transport layers and is rendered consistently on end-user devices.

KYC Relevance

Attestation represents a provider knowledge signal, while KYC supplies the verifiable evidence supporting that signal. Identity governance should therefore integrate entity vetting, use-case authorization, and lifecycle risk monitoring to enable auditable, end-to-end authentication.

Numeracle’s Perspective

Caller authentication must be implemented as a three-stage integrity model: identity must be verified, securely transmitted, and accurately rendered to consumers. Analytical or reputation-based approaches should function as supporting signals rather than primary substitutes for governance-based identity assurance.
