## Key Takeaways

- S.2666 would add an RMD bond requirement, exemption standards, traceback cooperation duties, and gateway authentication evaluation on top of existing 47 CFR 64.6305 rules.
- The bond functions as a pre-certification financial accountability tool for providers that cannot demonstrate legitimate operations or the ability to pay potential fines.
- Exemption criteria focus on FCC registration with USF contributions, state PUC licensing, securities exchange listing, and other indicators of established provider status.
- Traceback non-cooperation can result in public listing and downstream call blocking, and the bill directs the FCC to evaluate STIR/SHAKEN effectiveness for foreign-originated calls.
- Plura AI supports carrier compliance operations by enforcing STIR/SHAKEN authentication, DNC scrubbing, and consent logging at origination on its FCC-licensed infrastructure.1

## RMD Bond Requirement Under S.2666

S.2666 would direct the FCC to issue rules requiring certain voice service providers to post a bond of not more than $100,000 before certifying to the Robocall Mitigation Database that they are implementing robocall mitigation measures, if the Commission determines the bond is necessary to preserve the integrity of the RMD.2

The robocall mitigation database bond requirement operates as a financial accountability mechanism. The bond amount, set by the FCC up to $100,000, is intended to ensure that covered providers show financial capacity to cover potential fines or forfeitures. Providers that forfeit the bond would have those payments deposited in the general fund of the Treasury and recorded as revenue increases, per the CBO cost estimate dated May 26, 2026.

The bond would attach to providers the FCC determines cannot demonstrate legitimate ongoing operations, regulatory oversight sufficient to ensure accountability, or the ability to pay fines or forfeitures imposed by the Commission or other governmental enforcement authorities for violations of federal or state laws or regulations, per [S.2666 Section 5(c)(1)](https://civicgate.org/bill/s-2666-119).

Under current law, voice service providers must certify annually to the RMD that they are implementing robocall mitigation measures.2 S.2666’s bond requirement would add a pre-certification condition on top of that annual certification, according to the CBO’s May 26, 2026 estimate. Because the CBO expects few affected providers and a low likelihood of forfeiture, it projects only an insignificant revenue increase over the 2026-2036 period.

## Exemption Standards Under S.2666

S.2666 would require the FCC to establish criteria exempting a provider from the RMD bond requirement when the bond, as applied to that provider, is not necessary to deter unlawful robocall activity.

The statutory exemption framework under [S.2666 Section 5(b)(2)(B)](https://civicgate.org/bill/s-2666-119) directs the FCC to consider four factors when setting exemption criteria:

- Whether the provider is [registered with the FCC under 47 CFR 64.1195 and contributes to the Universal Service Fund (USF) under 47 U.S.C. 254(d)](https://civicgate.org/bill/s-2666-119)
- Whether the provider [holds a certificate of authority, license, or registration with a state public utility commission (PUC)](https://civicgate.org/bill/s-2666-119)
- Whether the provider is [an issuer with securities listed on a national securities exchange](https://civicgate.org/bill/s-2666-119)
- Whether the provider otherwise [presents indicia of being a bona fide, established communications service provider such that a bond would impose unnecessary burdens without materially improving enforcement of Section 227](https://civicgate.org/bill/s-2666-119)

The fourth factor operates as a catch-all for high-risk voice service providers not covered by the three enumerated criteria. Operationally, a provider assembling an exemption evidence file would gather FCC registration documentation, USF contribution records, state PUC certificates of authority or licenses, securities exchange listing documentation if applicable, and other documentation demonstrating legitimate, ongoing operations. The FCC has not yet established specific evidentiary standards, because the rulemaking would follow enactment. Consult the regulation or qualified counsel for obligations that apply to your organization.

The companion bill, H.R. 6152 Section 4(b)(2)(B), contains identical exemption factor language, so the exemption framework remains consistent across both versions of the Foreign Robocall Elimination Act.

## Traceback Participation Under S.2666

S.2666 would amend Section 13(d) of the Pallone-Thune TRACED Act to grant the registered industry traceback consortium immunity from any cause of action in court for receiving, sharing, or publishing covered traceback information, and would allow the FCC or the consortium to publish a list of voice service providers that refuse to participate in private-led traceback efforts.

Under [S.2666 Section 4(a)](https://civicgate.org/bill/s-2666-119), the bill would amend Section 13(d) of the Pallone-Thune TRACED Act to grant the registered consortium immunity from any cause of action in any court for receiving, sharing, or publishing covered information. [Covered information includes call detail records of suspected fraudulent, abusive, or unlawful robocalls, illegally spoofed calls, and other illegal calls, plus the names and identifying information of originating, carrying, routing, and transmitting voice service providers](https://civicgate.org/bill/s-2666-119).

The consequence of non-cooperation is significant. Under [S.2666 Section 4(b)](https://civicgate.org/bill/s-2666-119), the FCC, or the registered consortium in consultation with the FCC, may publish a list of voice service providers that refuse to participate in private-led traceback efforts or that are found to originate or transmit substantial amounts of unlawful robocalls. Public listing can trigger downstream call blocking by other networks. The FCC may also take enforcement action based on that information.

Under [47 CFR § 64.6305, gateway providers and non-gateway intermediate providers must commit in their robocall mitigation programs to respond within 24 hours to all traceback requests from the Commission, law enforcement, and the industry traceback consortium, and to cooperate with such entities in investigating and stopping illegal robocallers, while voice service providers are required to respond in a timely manner](https://www.govinfo.gov/content/pkg/CFR-2023-title47-vol3/pdf/CFR-2023-title47-vol3-sec64-6305.pdf).2 S.2666 adds the immunity grant and the public listing consequence, which strengthens the enforcement mechanism while leaving the existing cooperation obligation in place.

S.2666 Section 3 would [amend section 13(d)(2) of the Pallone-Thune TRACED Act to change the FCC’s robocall notice and reporting obligation from “annually” to “once every 3 years”](https://civicgate.org/bill/s-2666-119). That change reduces administrative overhead for the FCC and the consortium.

## Authentication And Gateway Duties Under S.2666

S.2666 would direct the FCC to examine whether STIR/SHAKEN adequately authenticates unlawful robocalls from foreign providers or foreign intermediate providers through U.S. gateway providers, and to examine how better implementation of traceback and caller ID authentication technology abroad would improve coordination in combating unlawful robocalls.

Under [S.2666 Section 2(d)(2)(G)](https://civicgate.org/bill/s-2666-119), the interagency taskforce would determine whether STIR/SHAKEN technical standards adequately provide call authentication for unlawful robocalls from foreign originating providers or foreign intermediate providers through gateway providers in the United States, and whether it would be desirable to encourage other countries to adopt those standards. This language creates an evaluation mandate rather than a new authentication requirement.

Gateway providers have been required to implement STIR/SHAKEN since June 30, 2023, per FCC rules in WC Docket No. 17-97, as documented in the CRS Report R48941 dated May 12, 2026. As of early 2026, large U.S. carriers have achieved over 95% STIR/SHAKEN implementation. Only about 21% of calls from smaller, non-facilities-based providers are made on IP-based networks, which contributes to only about 45% of total call traffic being fully signed, per the same CRS Report R48941.

S.2666 would direct the FCC robocall taskforce to examine how better implementation of technical solutions such as traceback and caller ID authentication in foreign originating countries would improve U.S.-foreign coordination against unlawful robocalls, and to determine whether STIR/SHAKEN adequately provides call authentication for unlawful robocalls from foreign originating providers or foreign intermediate providers through U.S. gateway providers. Providers that cannot demonstrate traceability face the same public listing and downstream blocking consequences described in the traceback section above.

To see how these new obligations compare with the rules carriers already follow, the next section maps S.2666’s requirements against current 47 CFR 64.6305 obligations.

## S.2666 vs. Current FCC Robocall Rules Under 47 CFR 64.6305

The table below summarizes how S.2666 would change each requirement area compared with current 47 CFR 64.6305 obligations, highlighting where the bill adds financial pre-clearance, exemption criteria, traceback consequences, and an evaluation mandate.

S.2666 would layer new requirements on top of existing 47 CFR 64.6305 obligations, moving the regime from a filing-and-compliance structure toward a filing-plus-financial-security structure for higher-risk providers.

| Requirement Area | Existing 47 CFR 64.6305 | Proposed S.2666 | What Changes |
| --- | --- | --- | --- |
| RMD Certification | Annual certification required | Annual certification plus pre-certification bond of up to $100,000 for certain providers | Adds financial pre-clearance condition |
| Exemption Standards | No statutory exemption criteria | FCC must establish criteria considering USF contribution, state PUC registration, exchange listing, and bona fide provider status | Creates statutory exemption framework |
| Traceback Cooperation | Providers must cooperate with traceback consortium | Consortium granted immunity for publishing traceback data; non-cooperative providers subject to public listing and downstream blocking | Adds immunity grant and public listing consequence |
| Gateway Authentication | STIR/SHAKEN required for gateway providers since June 30, 2023 | Taskforce to evaluate whether STIR/SHAKEN adequately authenticates foreign-originated calls through gateway providers | Adds evaluation mandate, with no new authentication requirement yet |

## H.R. 6152 vs. S.2666: Key Differences For Carriers

H.R. 6152, the House companion to S.2666, would authorize the FCC to impose a bond through rulemaking if needed, while S.2666 would require the bond and RMD registration as a condition before transmitting calls in the United States.

The structural difference centers on the necessity finding. Under H.R. 6152 Section 4(b)(1), the FCC would issue rules requiring a provider to post a bond of not more than $100,000 before filing a certification to the RMD, if the Commission determines posting the bond is necessary to preserve the integrity of the RMD. That necessity finding makes the H.R. 6152 bond a discretionary regulatory tool.

Under [S.2666 Section 5(b)(1)](https://civicgate.org/bill/s-2666-119), the FCC must issue rules requiring a provider to post a bond of not more than $100,000 before it may file a certification to the RMD, subject to the same necessity finding language. The CRS Report R48941 dated May 12, 2026 frames the key House-versus-Senate difference as structural. H.R. 6152 would authorize the FCC to impose a bond through rulemaking if needed. S.2666 would require the bond and RMD registration as a condition before transmitting calls in the United States. The CRS report frames S.2666 as the more prescriptive carrier-requirement bill, which makes it more operationally demanding for compliance teams.

The bond exemption criteria language is substantively identical across H.R. 6152 Section 4(b)(2)(B) and S.2666 Section 5(b)(2)(B), though the bills differ structurally on the bond requirement and in section numbering for traceback provisions. H.R. 6152 was ordered reported by the House Energy and Commerce Committee by a 37-0 vote on September 16, 2026.

## Legislative Status And Near-Term Carrier Actions

The Senate passed S.2666 with an amendment by unanimous consent on August 3, 2026, the House is considering H.R. 6152, and the FCC rulemaking would follow enactment.

[S.2666 was introduced in the Senate on August 1, 2025 by Sen. Ted Budd (R-NC) with cosponsors Sen. Jon Husted (R-OH), Sen. Raphael G. Warnock (D-GA), and Sen. Peter Welch (D-VT)](https://civicgate.org/bill/s-2666-119). The [Senate Commerce, Science, and Transportation Committee reported S.2666 on June 1, 2026](https://govinfo.gov/app/details/CRPT-119srpt122) with an amendment in the nature of a substitute, accompanied by written report No. 119-122. The Senate passed S.2666 with an amendment by unanimous consent on August 3, 2026. The bill was received in the House on August 10, 2026 and held at the desk.

H.R. 6152 was introduced on November 19, 2025 by Rep. Addison P. McDowell (R-NC-6) and ordered reported by the House Energy and Commerce Committee by a 37-0 vote on September 16, 2026.

Near-term preparation focuses on operations. Providers can audit current RMD filings for accuracy and completeness, confirm that USF contribution records, state PUC registrations, and securities exchange listings are documented and retrievable, and assess whether traceback cooperation procedures meet the existing 24-hour response standard under 47 CFR 64.6305. Consult the regulation or qualified counsel for obligations that apply to your organization.

As carriers prepare for these potential requirements, the operational question becomes how to enforce compliance at the point of origination. Plura AI addresses that layer directly.

## How Plura AI Supports Carrier Compliance Operations

Plura AI serves carriers and high-volume operators that need origination-level control on an FCC-licensed audio bridging carrier.

Voice originates on Plura’s domestic infrastructure rather than a third-party CPaaS. Branded caller ID is issued at the carrier level, STIR/SHAKEN authentication runs on every outbound call, and compliance controls sit at origination instead of being added later. Plura’s FCC-licensed AI contact center infrastructure is 100% U.S.-handled by architecture. Voice origination, model hosting, data storage, and call recording all sit on domestic infrastructure.

Plura enforces real-time DNC scrubbing, TCPA-litigator screening, automated quiet hours, and immutable consent logging inside the platform on every outbound contact.1 These capabilities align with a future S.2666 environment, where the FCC’s traceback and RMD frameworks would expect tighter documentation of origination practices.

## Conclusion: Position Your Network For S.2666

S.2666 would add a bond requirement, exemption standards, traceback cooperation duties, and gateway authentication evaluation on top of existing 47 CFR 64.6305 requirements. Providers that audit RMD filings and assemble exemption evidence now can move faster when the FCC opens rulemaking. The CRS Report R48941 and the CBO cost estimate offer primary source material for briefing executive teams and general counsel on the bill’s operational scope.

As described above, Plura’s origination-level enforcement and FCC-licensed infrastructure provide an operational foundation that aligns with the S.2666 compliance environment. Consult the regulation or qualified counsel for obligations that apply to your organization.
