Where to find your Capital One credit card number

Your Capital One credit card number appears in four places: on the front of your physical card, in your online account under Card Details, in your Capital One mobile app, and on your monthly statement. The easiest route depends on whether you have your card in front of you.

If you have the card itself, the 16-digit number is printed on the front. If you don't have it handy, log into your Capital One online account at capitalone.com, select the card you need, and look for the Card Details section — your full number displays there. The mobile app shows the same information under your card settings. Your most recent statement also lists the number, though usually in a partial format for security.

If you've lost your card and can't access your online account, call Capital One's customer service line at 1-800-955-9060. A representative can verify your identity and read your number to you over the phone. Have your Social Security number and date of birth ready for verification.
