Twilio + Claire AI: TCPA Compliance, SHAKEN/STIR Authentication, and HIPAA-Eligible Voice AI
Key Reference Data
Twilio TCPA Compliance Tools
Twilio provides built-in TCPA compliance tools through the Twilio platform: TCPA Wireless Consumer Protection (WCP) tools for wireless number identification, integration with Do Not Call (DNC) registry scrubbing services, time-of-day call window enforcement (TCPA prohibits calls before 8 AM or after 9 PM in the called party's time zone), and opt-out handling for SMS campaigns (automatic STOP processing). However, Twilio's tools support TCPA compliance — they do not enforce it. Enterprises must configure and activate these tools explicitly, and must obtain and document prior express written consent before initiating AI-generated outbound calls or SMS.
SHAKEN/STIR Caller ID Authentication
SHAKEN/STIR (Secure Handling of Asserted information using toKENs / Signature-based Handling of Asserted information using toKENs) is a FCC-mandated caller ID authentication framework. Full STIR/SHAKEN attestation ('A' level) requires that the originating carrier can verify: (1) the calling party is authorized to use the calling number, and (2) the number was not modified during transit. For AI voice calls from Twilio: use Twilio's STIR/SHAKEN-enabled phone numbers with A-level attestation to minimize call labeling as 'potential spam' by receiving carriers. Twilio obtained STIR/SHAKEN certification in 2021 and provides A-level attestation for numbers you own and control.
Integration Checklist
- Twilio HIPAA BAA ExecutionExecute Twilio's HIPAA Business Associate Agreement before using Twilio for voice or SMS communications involving Protected Health Information. Twilio's HIPAA BAA covers the Programmable Voice, Programmable SMS, and Conversations products. Confirm which Twilio products are covered by the BAA — not all Twilio products are HIPAA-eligible.
- Prior Express Written Consent DocumentationImplement consent capture and storage before any AI-generated outbound calls or SMS: store consent records with timestamp, consent text version, IP address, and mechanism of consent. Integrate consent verification with Twilio Studio or custom call initiation logic — check consent before dialing. Do not initiate AI voice calls or SMS without verified, documented consent.
- DNC Registry Scrubbing IntegrationIntegrate DNC registry scrubbing before each Twilio-triggered AI outreach campaign: scrub against FTC National DNC Registry (updated daily), applicable state DNC registries, and your internal suppression list. Use a real-time DNC lookup API integrated with Twilio Studio workflows. Log all DNC checks with timestamp for compliance documentation.
- STIR/SHAKEN ConfigurationConfigure Twilio phone numbers for A-level STIR/SHAKEN attestation: use numbers in your verified Twilio account that you own (not shared short codes or toll-free numbers which may receive lower attestation levels). Enable STIR/SHAKEN in your Twilio account settings. Monitor attestation levels — calls with C or no attestation are increasingly blocked by carriers.
- AI Voice Disclosure at Call StartConfigure all AI-generated voice calls to disclose AI use at the beginning of the call: 'This call uses an AI voice system.' Required by FCC TCPA guidance (2024), EU AI Act Article 50 (for EU calls from August 2026), and multiple state laws. Implement as a Twilio TwiML play instruction at the start of every AI call flow.
- Time-of-Day Calling Window EnforcementConfigure Twilio outbound call logic to enforce TCPA calling windows: do not initiate calls before 8 AM or after 9 PM in the called party's local time zone. Use the called party's area code to determine time zone. For mobile numbers with number portability, use a carrier lookup API to determine current time zone. Log time-zone determination for compliance evidence.
- SMS STOP Processing AutomationConfigure Twilio to automatically process SMS opt-outs: enable Twilio's built-in STOP keyword processing (Twilio automatically adds numbers to opt-out list on STOP reply), configure webhook to update your consent database on opt-out, and implement immediate cessation of all AI-generated SMS to opted-out numbers. Test STOP processing quarterly with test numbers.
- Twilio Monitor Compliance LoggingEnable Twilio Monitor for all AI-generated call and SMS logs: Twilio Monitor provides per-call and per-message logs including SID, status, direction, and duration. Export Twilio Monitor logs to your SIEM or compliance archive. For financial services FINRA compliance, Twilio call recordings and SMS messages must be archived in FINRA-compliant storage with 3-year minimum retention.
Frequently Asked Questions
Does Twilio satisfy TCPA requirements for AI voice calls?
Twilio provides the infrastructure and tools for TCPA-compliant AI voice calling, but does not itself ensure compliance — that is the enterprise's responsibility. Twilio's role: provide STIR/SHAKEN authenticated call origination, built-in DNC opt-out processing for SMS, time-of-day calling window controls, and consent storage tools. Enterprise's responsibility: obtain prior express written consent, document and verify consent before each call, implement DNC scrubbing, configure calling window enforcement, include AI voice disclosure at call start, and maintain call records. TCPA compliance is achieved through proper configuration of Twilio tools plus enterprise consent management processes.
What SHAKEN/STIR attestation level does Twilio provide?
Twilio provides A-level (full) STIR/SHAKEN attestation for calls originating from phone numbers that are: verified in your Twilio account, owned by your organization (not shared or leased), and originated directly from Twilio's platform (not transited through another carrier). A-level attestation is the strongest and least likely to be labeled as spam by receiving carriers. B-level attestation applies when the carrier can verify the call was initiated by the customer but cannot verify the number ownership. C-level (partial) attestation applies when neither the originating customer identity nor number ownership can be verified.
Is Twilio HIPAA-eligible for healthcare AI voice applications?
Yes, Twilio is HIPAA-eligible for specific products when a Business Associate Agreement (BAA) is in place. Twilio's HIPAA-eligible products include Programmable Voice, Programmable SMS, Programmable Messaging, Conversations, and other products listed in Twilio's HIPAA compliance documentation. The BAA is available to Twilio customers through the Twilio Trust Center. Note: some Twilio products (Twilio SendGrid for email, for example) are not HIPAA-eligible — verify the specific Twilio product before processing PHI through it.
What are the TCPA consent requirements for AI-generated SMS messages?
TCPA consent requirements for AI-generated SMS: for marketing/promotional SMS, prior express written consent is required — opt-in checkbox on web form, text-to-join keyword, or other documented consent mechanism that clearly describes commercial messages. For informational SMS (appointment reminders, transactional alerts): prior express consent (lower standard — verbal or written). For emergency or free-to-end-user SMS in limited circumstances: may not require consent. All SMS must include identification of the sender, message content disclosure, and opt-out instructions (STOP reply). Implement consent type tracking — marketing and informational require different consent levels.
How does Claire integrate with Twilio for AI voice and SMS?
Claire integrates with Twilio via: Twilio Programmable Voice (TwiML) for AI voice call handling — Claire processes voice input, generates AI response, and uses Twilio's text-to-speech for delivery; Twilio Conversations API for SMS/chat AI interactions; Twilio Studio for visual workflow builder integration; and Twilio Functions for serverless Claire API callouts within Twilio workflows. Consent verification, DNC scrubbing, and AI disclosure are implemented in Claire's pre-call logic before any Twilio outbound call is initiated. Claire provides Twilio compliance configuration templates for regulated industry customers.
