TCPA — 47 U.S.C. § 227 (LII / Legal Information Institute)

Cornell Law School's Legal Information Institute hosts the current codified text of the Telephone Consumer Protection Act (TCPA), 47 U.S.C. § 227.

Key provisions surfaced (2026-05-06, via FCC sources and search):

• Consent requirement. TCPA generally requires caller/sender consent before autodialed calls or texts to wireless numbers. Since 2003 the FCC has applied this to SMS (text calls to wireless numbers).
• Prior Express Written Consent (PEWC) for marketing. Autodialed or prerecorded-voice marketing texts to wireless numbers require written consent — cannot be oral.
• One-to-one consent rule (effective January 27, 2025 / FCC 24-24): consent must be obtained from each consumer for each individual seller separately; consent cannot be shared across brands or sold to lead aggregators.
• Revocation. If a party uses "any reasonable method" to revoke consent, the consent is definitively revoked; caller may not send additional messages. Maximum processing time: six business days.
• Penalties. $500 per violation; up to $1,500 per willful violation. Class-action exposure is significant.
