This bill strengthens consumer protections against unwanted robocalls and telemarketing calls by expanding and clarifying existing rules under the Telephone Consumer Protection Act. Specifically, it removes the word "residential" from the Do Not Call rules, meaning the protections now apply to all telephone subscribers including business lines, not just residential customers. The legislation also broadens what counts as an "automatic telephone dialing system" by including systems that use pre-recorded lists of numbers and clarifies that such systems dial numbers successively without human intervention. Additionally, the bill makes it easier for consumers to take legal action against violators by allowing private lawsuits for any violation rather than requiring multiple calls within a 12-month period. The Federal Communications Commission must issue updated regulations to implement these changes within 270 days of the bill's enactment.
