The FCC announced today all carriers and phone companies must adopt the STIR/SHAKEN protocol by June 30th, 2021. The regulatory requirement is designed to combat robocalls, specifically those that try to hide their phone numbers by allowing carriers to authenticate caller IDs.

The agency says the widespread adoption of STIR/SHAKEN will reduce the effectiveness of illegal spoofing, help law enforcement agencies identify bad actors and, most importantly, allow carriers to identify spammers before they ever call your phone. The FCC estimates fraudulent call schemes cost Americans approximately $10 billion every year. FCC Chairman Ajit Pai started pushing carriers to adopt the protocol in 2018. Congress also mandated the technology when it passed the TRACED Act last year.
