Notice how American Express doesn’t include any specific credit limit information in the card’s terms—that’s because the credit limit on a Blue Cash Preferred card differs from one applicant to another.  Your credit limit will fully depend on American Express’s assessment of your credit card application. For the most part, Amex will evaluate your creditworthiness, income, and credit score to determine your limit.  Keep in mind that the credit limit you start with isn’t necessarily your credit line forever. You can ask to get a credit limit increase by calling the American Express customer service at (800) 528-4800. But you don’t want to do this more than once a year.
