== FCC Mandate ==The STIR/SHAKEN mandate was approved unanimously, and the order sets a June 30, 2021 implementation deadline for all originating and terminating voice service providers. The agency is seeking comment on a proposal to extend the deadline for small voice service providers, as well as to require caller ID verification on non-IP voice networks, and expand the STIR/SHAKEN mandate to include intermediate voice service providers.The FCC estimates eliminating wasted time and nuisance from illegal robocall scams could result in $3 billion in cost savings annually, and protect Americans from robocall schemes that take approximately $10 billion from consumers each year.== Verifying Calls ==Major carriers will start verifying calls with other carriers using STIR/SHAKEN. March 2020 - The Federal Communications Commission adopted rules requiring phone companies implement the STIR/SHAKEN caller ID authentication protocol in their IP networks.March 2021 - Verizon has started authenticating caller IDs using STIR/SHAKEN in exchanges with other major wireless carriers, as well as Comcast.STIR/SHAKEN helps carriers verify that an incoming call is actually coming from the number that shows up on the caller ID and isn’t spoofed and originating from a different number. STIR/SHAKEN aims to help prevent and fight against scams and robocalls. == Limitations ==Even though the largest voice service providers are now using STIR/SHAKEN caller ID authentication standards it has yet to be deployed to any significant degree (2023) on landline phone networks. Furthermore, most companies that carry a lot of robocalls aren't yet required to follow the rules because of an exemption for carriers with 100,000 or fewer customers. They continue to operate because of an FCC exemption.
