My wife tried to move from her parents family share plan to her own plan. Already a Verizon customer, she was asked to fax her social security CARD to corporate verizon. When asked why her card is needed and not all others who sign up, she was told this was a "Random" policy, like being selected at TSA. This did not make her feel very comfortable in sharing such personal information. Is anyone able to provide a better answer as to why her card is needed? She has excellent credit and is already a customer! If she gets no answer, she is going to AT&T.
