This bill mandates the exclusive use of the National Verifier system for determining consumer eligibility for Lifeline service . It explicitly prohibits eligible telecommunications carriers from providing Lifeline service unless they have verified the consumer's eligibility through this national system, thereby eliminating the use of state-specific eligibility determination processes. The legislation aims to standardize and enhance the integrity of the Lifeline program's eligibility determinations across all states. By requiring universal use of the National Verifier, the bill seeks to ensure that only eligible individuals receive benefits, potentially reducing fraud and improving program efficiency.
