You will need to confirm with Capital One; however, when I got my card (which was about 2 years ago), I believe they indicated it reported to my personal credit report, but it did not for any auth users, but I would suggest you confirm that with Capital One, as anything can change with credit card companies and their reporting. I know when I had my Corporate Amex when I worked in the insurance industry, I had a card, and they requested my SS# too, but it did not report to my personal credit, but I know AMEX is a bit different.
