STIR/SHAKEN

STIR/SHAKEN is a set of standards that help verify if a phone call is legitimately coming from the number it claims to be. It uses digital authentication to reduce scam and spam calls, making it harder for robocallers to impersonate trusted numbers. When a call is made, the system checks its credentials and assigns a trust level, so your phone can flag or block suspicious calls. Overall, STIR/SHAKEN aims to improve caller ID accuracy and protect consumers from fraud.
