A duplicate subscriber error will occur when a carrier attempts to enroll a subscriber that already exists in NLAD. In the majority of cases, carriers can resolve this error by obtaining consent to transfer the subscriber's Lifeline Program benefit and completing a benefit transfer in NLAD.
If a prospective subscriber, who has been identified as a duplicate in NLAD, claims to not have an existing Lifeline Program benefit, please submit a duplicate subscriber dispute via email to NLAD Questions. Include the subscriber's name and contact information and USAC will investigate the duplicate subscriber dispute to determine if an exception will be provided.
