Why Attorneys General Robocall Warning Letters Matter
Robocalls have become one of the most disruptive and widespread consumer issues in the United States. Americans received over 50 billion robocalls annually, and many were tied to scams involving Medicare fraud, auto warranties, IRS impersonations, and fake loan services. Because of this escalation, state enforcement agencies have stepped up dramatically.
This is where attorneys general robocall warning letters come in. These warning letters are now one of the strongest tools used by state Attorneys General to crack down on illegal call traffic and force carriers to take responsibility for the robocalls they route.
In 2025, as AI-generated voice scams rise, these enforcement actions have become even more aggressive. Understanding how attorneys general robocall warning letters work is essential for telecom providers, VoIP carriers, call centers, and consumers who want protection from fraud.
What Are Attorneys General Robocall Warning Letters?
Attorneys general robocall warning letters are formal enforcement notices sent by state Attorneys General to telecom companies suspected of facilitating illegal robocalls.
These letters typically go to:
- VoIP carriers
- Gateway providers
- Smaller regional telecom companies
- Call-originating providers
- Companies previously flagged in traceback investigations
The purpose is to:
- Notify carriers that illegal robocall traffic is passing through their network
- Demand immediate corrective action
- Prevent future fraudulent call routing
- Document a provider’s compliance or non-compliance
Unlike automated spam-blocking solutions, these letters are legal directives backed by consumer protection laws and federal telecom regulations.
Why States Issue Robocall Warning Letters (Key Enforcement Reasons)

Attorneys general only issue these letters when there is substantial evidence of improper or illegal call traffic. Common triggers include:
- Failure to Block Illegal Traffic
If a provider repeatedly allows scam calls—especially spoofed or unverified calls—to pass through, AGs send warning letters demanding immediate mitigation.
- Suspicious VoIP Routing
Carriers routing disproportionately high volumes of international or “neighbor-spoofed” calls are often targeted.
- Lack of STIR/SHAKEN Compliance
STIR/SHAKEN is a call authentication system required for most carriers. Providers without proper implementation often receive letters.
- Ignoring Traceback Requests
The Industry Traceback Group (ITG) investigates robocall origins. Non-cooperative carriers are flagged to AG offices.
- High-Risk Providers Enabling Scam Traffic
If a provider’s network actively supports auto-warranty, IRS, or Medicare scam robocalls, state agencies intervene quickly.
- Attempts to Pressure International Call Sources
Warning letters often serve as the first step in broader federal or interstate enforcement actions.
These reasons help explain why attorneys general robocall warning letters are now viewed as one of the most effective tools in stopping illegal robocall schemes.
Inside the Warning Letters: What They Typically Demand
Although every letter differs by state, most attorneys general robocall warning letters include the following requirements:
✔ Response Deadline
Providers must respond—usually within 48 hours to 10 days—confirming receipt and cooperation.
✔ Cease-and-Desist Order
AGs demand that the provider stop carrying specific illegal call traffic immediately.
✔ Robocall Mitigation Plan
Carriers must share:
- What tools they use to block suspect traffic
- Their monitoring process
- Their complaint resolution steps
- Their upstream provider vetting procedures
✔ STIR/SHAKEN Compliance Proof
They must verify:
- Identity management practices
- Caller ID authentication
- Call origination traceability
✔ Upstream Provider Verification
If the provider partners with international or risky gateways, AGs demand documentation proving due diligence.
Failing to meet any of these requirements can trigger escalated enforcement.
Impact of Attorneys General Robocall Warning Letters on VoIP Providers
These letters can drastically affect carriers, especially smaller ones.
- Increased Legal Scrutiny
Once a provider receives a warning letter, state AGs begin active monitoring of their traffic patterns.
- Loss of Carrier Partnerships
Larger telecom companies may stop working with smaller carriers deemed risky.
- FCC Enforcement Escalation
If a provider ignores the letter, the AG forwards the case to the FCC.
The FCC can:
- Issue fines
- Block call traffic nationwide
- Revoke operating authority
- Lawsuits & Shutdown Risk
Several smaller VoIP carriers shut down after receiving multiple warnings or failing to comply.
- Reputational Damage
Being listed publicly as a non-compliant provider can deter clients and partners.
This is why providers now take attorneys general robocall warning letters extremely seriously.
- How These Warning Letters Protect Consumers
Consumers often don’t see what happens behind the scenes. But these enforcement actions lead to:
✔ Fewer Scam Calls
Targeting upstream carriers reduces illegal traffic before it reaches Americans’ phones.
✔ More Accountability
Carriers are now held responsible for verifying who uses their networks.
✔ Faster Enforcement
Once letters are issued, illegal call traffic often drops within 48–72 hours.
✔ Reduced Fraud Losses
Medicare scams, IRS impersonation calls, and loan scams become harder to execute.
Practical consumer benefits include:
- Fewer “spam likely” calls
- Safer caller ID information
- Reduced risk of identity theft
- Improved trust in phone communication
Key Legislation Behind the Crackdown
✔ TRACED Act (2019)
The foundation of modern robocall enforcement. It:
- Increased penalties
- Expanded AG authority
- Required STIR/SHAKEN authentication
✔ TCPA
The Telephone Consumer Protection Act makes unsolicited robocalls illegal.
✔ STIR/SHAKEN Mandates
These ensure caller ID authentication to reduce spoofing and fraud.
✔ Federal & State Consumer Protection Laws
AGs leverage these laws to enforce penalties and demand compliance.
Together, these legal frameworks empower state AG offices to send attorneys general robocall warning letters and force carriers to act.
Robocall Trends in 2025: How the Landscape Has Changed
Robocalling has evolved, and state enforcement strategies have adapted.
Major 2025 robocall trends include:
- AI voice cloning scams mimicking family members
- Foreign scam operations using US numbers
- Smishing (SMS phishing) increasing exponentially
- Scam hybrid attacks combining calls + texts + emails
- More sophisticated spoofing techniques
These trends are why more states are collaborating and issuing warning letters at record levels.
Real Examples of Attorneys General Robocall Warning Letters
While specific case details vary, the following scenarios illustrate common enforcement actions:
Example 1: Medicare Card Replacement Scams
A VoIP provider routed thousands of illegal Medicare scam calls daily. Multiple states issued warning letters, forcing immediate shutdown of offending traffic.
Example 2: Auto-Warranty Scam Network
A carrier repeatedly allowed auto-warranty robocalls traced back to overseas call centers. After receiving letters, the provider was required to block all associated traffic.
Example 3: Ignoring Traceback Requests
A small VoIP carrier ignored multiple traceback inquiries. AGs issued warning letters demanding compliance and threatening FCC escalation.
These examples show how attorneys general robocall warning letters directly disrupt scam networks.
What Telecom & VoIP Providers Must Do to Stay Compliant
✔ Implement a Robocall Mitigation Plan
This is mandatory for all carriers.
✔ Monitor Traffic Patterns
High-volume spikes often signal fraud.
✔ Fully Deploy STIR/SHAKEN
Caller ID authentication reduces spoofing.
✔ Cooperate with Traceback Groups
Required under TRACED Act rules.

Especially from known scam regions.
Staying ahead of these requirements minimizes the risk of receiving attorneys general robocall warning letters.
What Consumers Should Do If They Still Receive Robocalls

✔ Report Calls to the FTC
ReportFraud.ftc.gov
