Mass text messaging in the United States is subject to several federal and state regulations. Understanding and complying with these laws is essential for any business or organization sending bulk SMS messages. The primary federal law governing mass text messaging is the Telephone Consumer Protection Act (TCPA).

US mass messaging laws TCPA

The Telephone Consumer Protection Act (TCPA)

The TCPA, enacted in 1991 and updated multiple times since, is the primary federal law regulating mass text messaging. Key TCPA requirements for SMS include:

  • Prior Express Written Consent: For marketing messages, you must obtain explicit written consent from each recipient before sending SMS. This typically means a signed agreement (digital or paper) or an online opt-in form that clearly discloses that the consumer will receive recurring marketing texts.
  • Identification: Every text message must clearly identify who is sending it.
  • Opt-Out Mechanism: Every marketing SMS must include clear instructions for opting out (e.g., "Reply STOP to unsubscribe"). Opt-out requests must be honored immediately.
  • No Automated Messages Without Consent: Sending automated or prerecorded messages to cell phones without prior consent is prohibited.
  • Time Restrictions: Messages may only be sent between 8:00 AM and 9:00 PM local time of the recipient.

TCPA Exemptions

Certain types of messages are exempt from some TCPA restrictions, including emergency alerts sent by government agencies, messages sent in response to a consumer-initiated text, and some healthcare-related communications. However, even exempt messages should follow best practices.

State Laws

Several states have enacted additional SMS marketing regulations that may be stricter than the TCPA. California's CCPA (California Consumer Privacy Act) imposes additional data privacy requirements that affect how consumer contact information is collected and used. Always check the laws of the states where your recipients reside.

FCC Regulations

The Federal Communications Commission (FCC) enforces the TCPA and issues interpretive rulings. The FCC has clarified that the TCPA applies to text messages in addition to phone calls, and has expanded the definition of autodialer equipment covered by the law.

Penalties for Non-Compliance

TCPA violations can result in significant penalties: $500 per violation for inadvertent violations, and up to $1,500 per violation for willful or knowing violations. With the potential for class action lawsuits, TCPA non-compliance can be extremely costly.

Best Practices for US Compliance

  • Maintain documented proof of consent for every recipient
  • Honor opt-out requests within 24 hours (immediately is best)
  • Keep opt-in lists current and scrub against the National Do Not Call Registry
  • Consult legal counsel when in doubt about compliance
