When I try to add him online, it says "We need to verify their SSN to securely provide them with online access. We may use SSNs to more accurately identify cardholders, report information and service accounts."
I have my checking, savings, and 3 credit cards with this bank (Capital One). Won't it look bad to open a new account just to add him? Surely I'm not the only person who has wanted to add an authorized user without a SSN before.
