FCC Compliance Guide: Caller ID Authentication (Small Entities)

FCC Notice
June 21, 2021

The Federal Communications Commission issued a small-entity compliance guide to help organizations understand caller ID authentication requirements, including deployment expectations for STIR/SHAKEN frameworks and associated robocall mitigation obligations. The guide is intended to clarify practical compliance steps for smaller providers by summarizing obligations established under the TRACED Act and related Commission Reports and Orders issued in 2020.

The compliance guide explains who must implement authentication protocols, what extension or exemption pathways may be available, and how mitigation responsibilities apply when full STIR/SHAKEN deployment has not yet been achieved. By translating regulatory language into operational guidance, the document reinforces that mitigation is not limited to large network operators but is an ecosystem expectation across organizations of varying scale.

KYC Relevance

Even small entities must be able to identify and validate their customers in order to support attestation and mitigation claims. Know Your Customer controls serve as the foundational mechanism that enables providers of any size to substantiate authentication decisions and regulatory filings.

Numeracle’s Perspective

KYC programs should be designed to scale with organizational size and operational complexity while maintaining consistent evidence standards. Identity documentation, number right-to-use validation, and defined risk thresholds should be preserved to ensure that compliance certifications remain defensible, traceable, and aligned with actual business and network behavior.
