The Supreme Court ruled in Facebook v. Duguid that an "automatic telephone dialing system" (ATDS) requires the use of a random or sequential number generator, providing clarity on the definition under the Telephone Consumer Protection Act (TCPA). While this ruling clarifies restrictions on calls and texts made using automated dialing methods, it does not affect other portions of the TCPA or state laws restricting autodialer usage. Businesses should continue to ensure that their communications are wanted and expected before reaching out with a call or text, and consult legal counsel for specific considerations related to their operations.
