The Federal Communications Commission (FCC) is turning up the heat on illegal robocalls. Moving beyond general policy commitments, the Commission is shifting toward a strict, prescriptive regime focused on aggressive verification, monitoring, and proactive enforcement.
At its May 20, 2026 Open Meeting, the FCC is considering a major draft proposal (FNPRM) aimed squarely at the “bad actors” enabling unlawful traffic. Following on the heels of the recent “Know-Your-Customer” (KYC) rules, this new initiative focuses heavily on “Know-Your-Upstream-Provider” (KYUP) obligations and massive upgrades to the STIR/SHAKEN framework.
Here is a quick breakdown of the five major changes on the horizon and how voice service providers can prepare.
5 Key Pillars of the New Proposal
1. Expanded KYUP Requirements: Current rules require “reasonable and effective” steps to block unlawful traffic. The new proposal mandates active, ongoing vetting. Providers must collect, verify, and monitor upstream providers’ business data and traffic patterns, and swiftly terminate relationships with high-risk actors.
2. Enhanced STIR/SHAKEN Oversight: To lock bad actors out of the authentication ecosystem, the FCC plans to tighten controls over token issuance, certification authorities, and enforcement procedures.
3. Higher Attestation Standards: The proposal formally codifies the A-, B-, and C-level attestation framework with explicit definitions. Crucially, it bans “improper attestations” where a provider overstates their knowledge of a caller’s identity.
4. Closing Authentication Gaps: The FCC wants to eliminate remaining STIR/SHAKEN hardship extensions, prohibit intentional routing that strips authentication data, and require intermediate providers to authenticate unauthenticated calls.
5. Cracking Down on Foreign Traffic: Expect heightened scrutiny and tighter safeguards on international call paths and gateway providers to block illegal foreign-originated traffic from entering U.S. networks.
KYC vs. KYUP: The Dual-Compliance Reality
If adopted, providers will need to manage two parallel compliance tracks:
- KYC (Know Your Customer): Vetting end-user customers before service activation.
- KYUP (Know Your Upstream Provider): Vetting and monitoring the carriers, wholesalers, and resellers handing off traffic to your network.
Conclusion: In future enforcement investigations, the FCC is highly likely to evaluate your onboarding, contracts, analytics, and attestation practices as a single, unified workflow.
How Providers Can Prepare Now
While these rules aren’t final, they will launch a major comment cycle that impacts everyone from originating providers and VoIP resellers to enterprise voice platforms. Smart providers should audit their systems today:
- Identify and map all upstream providers sending traffic to your network.
- Compare your current onboarding and vetting processes against the FCC’s proposed baseline.
- Review third-party signing relationships to ensure your company maintains ultimate control over attestation decisions.
- Establish clear escalation and termination protocols for high-risk upstream partners.
