Your account number is on your physical card, your monthly statement, and in the Capital One mobile app

The fastest way to find your Capital One credit card account number is to look at the card itself. The 16-digit number printed on the front of your card is your account number.

Finding the number on your physical card

Checking your monthly statement

Every paper statement Capital One mails to you includes your account number. Look near the top of the first page, usually in the upper right or upper left corner. The statement will label it as "Account Number" or "Your Account Number" followed by the 16-digit number.

Statements are typically mailed or made available online between the 1st and 10th of each month, depending on your billing cycle.

Frequently Asked Questions

Is my account number the same as my card number?

Yes. The 16-digit number on your Capital One credit card is both your card number and your account number. They are the same thing. If you get a replacement card, the number will change, so you'll need to update any services that use your card number.

Can I find my account number without logging in?

Yes. Your physical card and paper statements both show your account number without requiring a login. If you don't have either, you'll need to call Capital One customer service, and they can provide it after verifying your identity.

What if my account number looks different on different documents?

Your account number should be the same 16-digit number everywhere — on your card, statement, app, and online account. If you see different numbers, double-check that you're looking at the account number field and not another number like a reference number or transaction ID. Contact Capital One if the numbers genuinely don't match.

Do I need my account number to make a payment?

You don't always need it. You can make payments through the Capital One app or website by logging in, or by phone without providing the number if you verify your identity first. However, having your account number handy makes the process faster, especially if you're paying by mail or setting up automatic payments with another bank.
