Can the card issuer request information about my income, my age, and my Social Security Number when I apply for a credit card?
Yes. Before granting credit to you the card issuer may ask about your income so they know whether you can pay the required minimum periodic payment. The card issuer may also ask about your age so they know you are old enough to have the legal ability to enter into a contract. Also, the card issuer may ask for your social security number to get your credit report.
