CPNI Rules (47 CFR Part 64 Subpart U) — Regulatory Reference

CPNI rules restrict telecommunications carriers to using Customer Proprietary Network Information — call detail, routing data, network usage — only for purposes related to providing the service for which it was collected, unless the customer has explicitly approved broader use (§64.2005, §64.2007). When AI agents query call records for tasks like churn prediction, marketing personalization, or fraud investigation, carriers must demonstrate that each retrieval was authorized for that purpose. An agent that pulls CPNI for a purpose outside the approved scope creates a compliance violation regardless of whether the data was monetized. Purpose-limited enforcement at the point of retrieval is therefore the technical requirement the regulation implies.

Section 64.2009 requires carriers to implement safeguards preventing unauthorized access to and use of CPNI. The FCC has interpreted this to include access controls, training, and internal procedures that enforce the purpose-limitation requirement. For AI-driven pipelines, the practical implication is that any agent or automated process reading call records must be governed by a control that verifies the retrieval is purpose-authorized before the data enters the agent's context. Logging the agent's identity, the source accessed, the policy governing that access, and the timestamp of the decision satisfies the evidentiary expectations that accompany a safeguard regime — particularly when the FCC opens an inquiry.

Section 64.2011 requires telecommunications carriers to file an annual certification with the FCC confirming that the carrier has established operating procedures to ensure CPNI compliance, that supervisory review of marketing campaigns using CPNI has occurred, and that no actions were taken inconsistent with the rules. The certification must be signed by an officer. For AI-assisted marketing and customer service operations, the certification requires demonstrable evidence that AI access to CPNI was purpose-limited throughout the year. A timestamped, tamper-evident audit record of every agent evaluation — showing which policy governed each retrieval and whether it was allowed or denied — provides the dated, measurable evidence an officer can rely on when signing.

AutoPIL sits between AI agents and CPNI data sources and evaluates every retrieval request against a purpose-limitation policy before the data reaches the agent. Policy TEL-CPNI-2005-001 enforces the §64.2005 purpose boundary at the retrieval layer; policy TEL-CPNI-2011-001 is designed to produce the dated audit evidence needed for §64.2011 annual certification. Every evaluation writes a cryptographically chained audit event recording the agent identity, source accessed, policy version that governed the decision, allow/deny outcome, and timestamp. The source registry tracks which CPNI data assets are governed. The result is a continuous, verifiable compliance record without requiring changes to the underlying AI stack.

The FCC enforces CPNI rules through forfeiture orders, which have historically ranged from tens of thousands of dollars for individual violations to multi-million-dollar consent decrees for systemic failures across a carrier's operations. Violations do not require proof of customer harm — unauthorized use or disclosure of CPNI is itself the violation. AI agents that access call records without per-request purpose verification amplify risk because a single misconfigured pipeline can generate thousands of individual retrieval events, each a potential separate violation. The FCC has also signaled scrutiny of data broker and third-party access patterns, which includes automated systems acting on behalf of a carrier.
