A September 18 deadline is fast approaching for certain voice service providers to comply with expanded STIR/SHAKEN requirements approved last year by the Federal Communications Commission (FCC).

The FCC’s Eighth Report and Order, adopted on November 21, 2024, increased STIR/SHAKEN obligations for voice service providers using third parties to implement their caller ID authentication frameworks. While initially the Order appears limited to the FCC’s STIR/SHAKEN regulatory requirements, impacted voice service providers may also find themselves newly exposed to obligations under the FCC’s Universal Service Fund (USF). Depending on a voice service provider’s individual circumstances, these USF obligations could have significant financial impacts, as well as potential exposure to FCC enforcement actions.
