Facebook Inc. v. Duguid

Facebook Inc. v. Duguid is a United States Supreme Court case concerning the definition and function of autodialers. The main issue was Facebook’s notification system, which sends automated text messages to alert users of attempted logins to their accounts. Noah Duguid, who sued Facebook, argued that such notifications were illegal. However, the Supreme Court decided in favor of Facebook.

In the ruling, the US Supreme Court also clarified the definition of an automatic telephone dialing system (ATDS) under the Telephone Consumer Protection Act (TCPA). The Supreme Court ruled that autodialers are defined by their function to store or produce telephone numbers from a random or sequential number generator.
