Have you noticed something new on your phone recently? Some calls I’ve received now have the message “Calls with a check mark have been verified by the carrier.” It started last Wednesday, and it’s an attempt to identity spoofed phone numbers, especially from local area codes.
Under the Stir/Shaken protocol, carriers are required to certify, with varying confidence levels, that calls really are coming from the numbers displayed on caller ID. The deadline for most big carriers to implement the standards was Wednesday and the major carriers have all said they've signed on.
The idea is this: When your wireless carrier processes an inbound call that doesn't have a certification letting it know the number is legitimate, the carrier will be able to block it before your phone ever starts ringing.
