Connecticut Consent Requirements
What consent you need before calling or texting consumers in Connecticut
Mini-TCPA State — Stricter than Federal
Connecticut has enacted Conn. Gen. Stat. § 42-288a et seq. which imposes consent requirements beyond what federal TCPA requires. Federal compliance alone is not enough.
One-to-One Consent Required for Some Channels
Consent obtained from a lead generator or shared with multiple sellers is NOT valid in Connecticut for affected channels. You must obtain consent specifically naming your company.
ATDS Definition Broader than Federal
Connecticut uses a broader definition of automated dialing equipment than the federal TCPA post-Facebook v. Duguid. More dialing systems may trigger consent requirements under state law.
Consent Requirements by Channel
| Channel | Consent Level | One-to-One | ATDS Broader | Checkbox Valid |
|---|---|---|---|---|
| Voice Call | Prior Express | No | Yes | Not Sufficient |
| SMS | Written Consent Required | Required | Yes | Valid |
| AI Voice | Written Consent Required | Required | Yes | Not Sufficient |
| Prerecorded | Written Consent Required | Required | Yes | Valid |
| Ringless Voicemail | Written Consent Required | Required | Yes | Valid |
| MMS | Written Consent Required | Required | Yes | Valid |
| Fax | Written Consent Required | No | No | Not Sufficient |
Channel Details
Voice Call
Notes
Manual voice calls to non-DNC numbers require prior express consent but not written consent. ATCS-assisted calls require prior consent per the ATCS Act. Calling hours are 9 AM to 9 PM — stricter than the federal 8 AM to 9 PM window. Must identify yourself within 30 seconds.
ATDS Definition
Connecticut defines ATCS (Automated Telephone Calling System) as any device that can store or produce telephone numbers and dial them without human intervention. This is similar to the pre-Duguid federal standard.
Exemptions
EBR exemption available for manual calls. Licensed professionals with existing clients may qualify.
Statute
Conn. Gen. Stat. § 52-570c; § 42-288a
SMS
Notes
SMS marketing requires prior express written consent when using automated systems. The FCC one-to-one consent rule (Jan 2025) applies. Connecticut courts have not yet extensively litigated SMS under the ATCS Act, but the statute's broad language covers text messages.
ATDS Definition
Text messages sent via automated platforms fall under the ATCS definition. Any system that stores numbers and sends messages without individual human initiation triggers the consent requirement.
Exemptions
Transactional texts to existing customers may be exempt.
Statute
Conn. Gen. Stat. § 52-570c; § 42-288a
AI Voice
Notes
AI voice calls in Connecticut require prior express written consent. The ATCS Act was written broadly enough to capture AI voice technology. There is no specific AI disclosure requirement yet, but CUTPA's deceptive practices prohibition means failing to disclose AI use could be separately actionable.
ATDS Definition
AI-generated voice calls are treated as automated calling systems under Connecticut law. The ATCS Act covers any device that dials without human intervention, and AI voice systems clearly fall within this scope.
Statute
Conn. Gen. Stat. § 52-570c; § 42-288a
Prerecorded
Notes
Prerecorded voice messages to Connecticut consumers require prior express written consent. The message must identify the caller and provide a callback number within the first 30 seconds. Violations carry $500 per call.
ATDS Definition
Prerecorded messages are explicitly covered by the ATCS Act. Any prerecorded or artificial voice message delivered via automated system requires prior consent.
Exemptions
Emergency notifications and certain government messages are exempt.
Statute
Conn. Gen. Stat. § 52-570c
Ringless Voicemail
Notes
RVM is not specifically addressed in Connecticut statute, but the broad ATCS definition likely covers it. Conservative approach: treat ringless voicemail the same as a prerecorded message requiring prior express written consent.
ATDS Definition
Ringless voicemail deposits are not explicitly addressed but fall under the broad ATCS definition as automated messages delivered to consumer phone systems.
Statute
Conn. Gen. Stat. § 52-570c
MMS
Notes
MMS marketing messages follow the same rules as SMS. Prior express written consent required for any automated sending system.
ATDS Definition
MMS messages are treated identically to SMS under Connecticut's ATCS definition.
Exemptions
Same exemptions as SMS apply.
Statute
Conn. Gen. Stat. § 52-570c
Fax
Notes
Unsolicited fax advertising requires prior express written consent under federal law. Connecticut defers to federal TCPA for fax regulation.
ATDS Definition
Fax communications are governed by federal TCPA and the Junk Fax Prevention Act. Connecticut does not have a separate state-specific fax statute.
Exemptions
EBR exemption available under federal law with opt-out notice on each fax.
Statute
Conn. Gen. Stat. § 42-288a; 47 U.S.C. § 227
What Counts as Valid Consent
Recipient must have previously expressed willingness to receive calls/texts. Oral consent typically sufficient.
Written consent required — electronic (checkbox, signature) or signed paper. Must be clear and conspicuous. Cannot be a precondition of purchase.
Universal rule: Consent must be freely given — it cannot be a condition of purchasing a product or service. Bundled consent (buried in terms of service) is not valid for TCPA purposes.
