The deadline for STIR/SHAKEN certification is today
By Mitchell Clark Jun 30, 2021
T-Mobile announced on Wednesday that it is fully compliant with the FCC's new anti-spoofing protocol, telling the FCC that its now certifying that calls from its network are protected against impersonation by scam callers using the STIR/SHAKEN protocol.
Verizon also announced that it's verifying that the number that shows up on your caller ID is actually the number that's calling you using the same STIR/SHAKEN protocol. The two major carriers announcing their progress on the same day isn't a coincidence -- Wednesday, June 30th, is the deadline the FCC set for major carriers to implement STIR/SHAKEN. An AT&T spokesperson told The Verge that the carrier also met the deadline, as it filed on the 29th, and said that "all LTE and
5G calls originating on [its] wireless network are STIR/SHAKEN compliant."
