Executive Summary

Unwanted telemarketing calls, illegal robocalls, and spoofed caller IDs together make up one of the most persistent consumer-protection challenges in the United States. Despite the presence of the National Do Not Call (DNC) Registry, the Telephone Consumer Protection Act (TCPA), and a growing suite of federal and state enforcement tools, billions of illegal calls are placed annually.

This white paper clarifies the statutory penalties for calling numbers on the Do Not Call list, explains why spoofed calls are especially difficult to manage, evaluates the current regulatory landscape, and proposes actionable recommendations for consumers, carriers, regulators, and legislators.

1. Introduction

The National Do Not Call Registry was established in 2003 with the goal of reducing unwanted telemarketing calls to consumers. Over 250 million phone numbers are currently registered. While the Registry greatly reduced legitimate telemarketing, it has sparked a new era of illegitimate activity where unregistered call centers, offshore scammers, and VoIP-based autodialers ignore the law entirely.

The proliferation of caller-ID spoofing, made easy by inexpensive digital telephony technology, allows bad actors to disguise their identity, evade detection, and erode trust in the telephone network.

2. Legal Framework Governing Unwanted Calls

2.1 The Telephone Consumer Protection Act (TCPA)

The TCPA limits telemarketing and automated dialing practices. Violations include:

Calling any number listed on the National Do Not Call Registry without valid consent. Using automated dialing or prerecorded messages without consumer consent. Calling during prohibited hours (before 8 a.m. or after 9 p.m. local time). Failing to maintain an internal “do not call” list.

2.2 FCC and FTC Regulations

The Federal Communications Commission (FCC) enforces TCPA violations involving robocalls, caller ID spoofing, and autodialers.

The Federal Trade Commission (FTC) enforces violations involving deceptive or unfair telemarketing practices.

3. Penalties for Calling Numbers on the Do Not Call List

Violations of DNC rules carry substantial financial consequences.

3.1 Civil Statutory Damages

Under the TCPA, consumers may sue violators for:

$500 per illegal call or actual damages, whichever is greater. Up to $1,500 per call if the court finds the violation was knowing or willful.

These penalties apply per call, making mass autodialing risky for legitimate businesses.

3.2 Federal Regulatory Penalties

Regulators may impose additional administrative fines:

The FTC can levy fines over $50,000 per call for violations of Do Not Call rules in enforcement actions. The FCC regularly issues multimillion-dollar fines for severe robocall campaigns or caller-ID spoofing schemes.

3.3 State-Level Penalties

Many states have parallel DNC statutes that can add:

Fines ranging from $1,000 to $25,000 per violation. Class-action eligibility under state consumer-protection law. Enhanced penalties for senior-targeted scams or repeat offenders.

3.4 Criminal Liability in Extreme Cases

While rare, fraudulent robocall schemes that involve identity theft, extortion, or financial fraud can trigger:

Federal wire fraud statutes Criminal conspiracy charges International cooperation through DOJ and Interpol when offshore operations are involved

4. Why Spoofed Calls Are So Prevalent

Despite enforcement, spoofing continues to escalate due to several structural challenges.

4.1 Caller-ID Spoofing Technology is Cheap and Ubiquitous

Software enables anyone to substitute a fake number—often a local “neighbor spoof” number—to increase the chance a consumer answers. VoIP tools make this trivial.

4.2 Offshore and Unregulated Call Centers

Many illegal campaigns originate outside of U.S. jurisdiction, limiting enforcement reach even when penalties are clearly defined.

4.3 Automated Dialing at Massive Scale

Robocall systems can dial millions of numbers per hour, making low success rates acceptable for scammers.

4.4 Difficulties of Traceback and Enforcement

Even with industry traceback groups, spoofing masks:

The originating caller The call pathway The responsible entity

Allowing malicious actors to disappear quickly.

4.5 Carriers Historically Had Limited Incentives

Only in the last few years have U.S. carriers been legally required to implement authentication technologies like STIR/SHAKEN.

5. Current Countermeasures and Their Effectiveness

5.1 STIR/SHAKEN Caller Authentication

A framework that cryptographically verifies whether the number shown on caller-ID is legitimately associated with the originating carrier.

Impact:

Effective on major VoIP and wireless carriers Less effective on calls entering the U.S. from foreign networks Does not block calls by itself; only signals trust level

5.2 Carrier-based Spam Filtering

Most major carriers use:

AI-based spam detection Reputation databases Known-robocall fingerprints

Effectiveness varies but has reduced some categories of high-volume spam.

5.3 FTC and FCC Robocall Enforcement Actions

Recent enforcement trends focus on:

Shutting down gateway carriers that allow illegal international traffic Targeting repeat offenders with multimillion-dollar fines Collaborating with call-authentication consortia

5.4 Private Consumer Actions

TCPA lawsuits by individuals have grown significantly.

While law firms target large violators, individual consumers increasingly win judgments against smaller companies.

6. What Consumers Can Do

6.1 Maximize Legal Protection

Register both landline and mobile numbers on the National Do Not Call Registry. Maintain records (screenshots, call logs) of repeated violations. Submit complaints to the FTC (Do Not Call violations) and FCC (robocalls/spoofing).

6.2 Use Available Call-Blocking Tools

Enable carrier-level spam protection (often free). Use device-based call filters that silence unknown or suspicious calls. Enable “Silence Unknown Callers” features on smartphones where appropriate.

6.3 Avoid Engaging with Suspicious Calls

Never press numbers or speak to automated prompts. Do not return calls to suspicious numbers. Avoid saying “yes” to unknown callers (some scams attempt to record consent-sounding audio).

6.4 Consider Private Legal Action

For companies operating inside U.S. jurisdiction, consumers may:

Demand internal do-not-call compliance Pursue statutory damages under the TCPA Join class actions against large offenders

7. Policy Recommendations

7.1 Strengthen International Cooperation

Illegal call centers in India, Pakistan, the Caribbean, and Eastern Europe frequently target U.S. numbers. Policymakers should expand bilateral and multilateral programs that:

Identify and shut down criminal call centers Penalize offshore VoIP carriers that facilitate illegal traffic Seize assets tied to spoofing activity

7.2 Expand STIR/SHAKEN to International Gateways

Require foreign carriers passing calls into the U.S. to use authenticated pathways or risk traffic rejection.

7.3 Increase Penalties for Gateway Carriers

Domestic gateway carriers that repeatedly allow illegal traffic should face:

Loss of operating license Mandatory compensation funds for victims Civil penalties scaled to call volume

7.4 Enhance Public Education

Consumers need clear messaging about:

The legitimacy of political, charity, and survey exemptions How spoofing disguises calls Which behaviors place them at greatest risk of fraud

7.5 Modernize the TCPA

TCPA definitions—from “autodialer” to “prior consent”—predate most digital technologies. Modernization should:

Clarify definitions to include modern VoIP and AI-generated robocalls Broaden liability for companies outsourcing telemarketing to third parties Penalize use of AI voice cloning for malicious calls

8. Conclusion

The Do Not Call Registry and TCPA remain essential tools in protecting consumers from unwanted calls. However, as spoofing and offshore robocalls grow in sophistication, traditional enforcement alone cannot stop the problem.

A comprehensive strategy—combining stronger penalties, carrier accountability, international enforcement, and consumer resilience—is necessary to restore trust in telephone communications.

There is no single solution to the problem of illegal robocalls, but the combination of legal deterrence, technological verification, and consumer tools represents the most viable path toward minimizing their prevalence.
