Why is my PO Box on file not sufficient in order to add a line onto my account when I am not having anything mailed to me? I bought a brand new Ipad with Cellular and messaged Verizon to get it added to my account. The Rep told me they could not process it because I have a PO Box on file? Why does this matter? You aren't shipping me anything and its the address associated with my bank card. I guess I will have to shop around for a provider that this wont be an issue at as I have no choice. I only have a PO Box.
