Duplicate Resolution

Duplicate Subscribers

Duplicate subscribers are individuals who are receiving multiple Lifeline Program-supported services, whether within a state or across multiple states. They are identified using the following NLAD data: subscriber's last name, date of birth, and last four digits of their Social Security Number.
