Check Out Our Frequently Asked Questions

  • What should I do if my credit card is lost or stolen?

    If your card is lost or stolen, you should report it immediately – contact us.

  • How can I make a payment on my account?

    Paying online is the most convenient way to make payments on your account. You can pay through your financial institution’s online banking site, or by taking advantage of our pre-authorized debit service, so your payments are made on time, every time. See below for online payment options available to you.

    How to pay through your financial institution’s online banking site:

    1. Log in to your bank’s online banking site.

    2. Add “Capital One Mastercard” as a new payee to your payee list.

    3. Make your payment to Capital One Mastercard.

    Please note that it can take 2-3 business days for your online payment to post.

    How to set up pre-authorized debit payments:

  • What are recent transactions?

    In online banking, recent transactions refer to all activity on your account since your most recent available statement. Transactions appear online as soon as they’re pending or posted to your account. If you haven’t made any transactions since your last statement, this section will not have any entries. If you’ve made a transaction and it doesn’t appear in online banking, that transaction may not have posted to your account yet.

  • How do I dispute a transaction?

    Below are the steps you can take to dispute a transaction:

    1. Click “View Account”.

    2. Find the transaction in the list of posted transactions that you’d like to dispute (pending transactions cannot be disputed).

    3. Click on the transaction to see more details, then click the “Report a problem” link.

    If you can’t find your transaction, or if it’s older than 90 days, please call our Fraud Solutions Department at 1-866-381-0447.

  • How can I check the status of my credit card application?

    Call 1-877-277-5901 and select option 3 to check the status of your credit card application.
