Understanding The TCPA & CTIA


TCPA Overview

In 1991, Congress pass the Telephone Consumer Protection Act (TCPA) as an amendment to the Communications Act of 1934. The purpose of the TCPA is to protect American consumers from telephone solicitation and telemarketers using automated phone equipment to place calls. As technology has progressed, the TCPA has been interpreted to apply to phone calls, text messages, fax communications, and prerecorded voice messages. Per the TCPA, companies must abide by Do Not Call Registry restrictions and obtain explicit consent (“opt in”) before contacting consumers.

TCPA Guidelines

  • Contacts must provide consent (“opt-in”) before receiving messages.
  • Telephone marketing solicitation requires proof of written consent. 
  • Electronic consent may be obtained via mobile keyword and online sign-up pages. 
  • Written consent obtained via paper sign-up must specify SMS messaging consent.
  • Non-solicitation messages include internal communications and emergency alerts.
  • Non-solicitation messages also require documented written or verbal consent.
  • Solicitation messages may be sent between 8:00 AM and 9:00 PM, recipient’s time.
  • Message frequency and content should match opt-in disclosures.
  • Example: Subscribers opted-in to account updates should not receive marketing.

  •  Messaging companies may not restrict opt-out methods.
