MBNA Fraud Alerts available at no cost on all MBNA Credit Cards.

MBNA Fraud Alerts is a quick and hassle-free way for you to be notified if there is suspicious activity on your MBNA credit card(s).

How Does It Work?

If we have your current mobile/phone numbers and email address on file, MBNA Fraud and Security will attempt to alert you regarding any suspicious activity on your MBNA credit card(s).

  1. With SMS and Voice Alerts
    If you respond to the alert with an 'N', it tells us that the transaction is invalid - your account (including all authorized users) will be blocked, and you will be prompted to speak to a live agent. If you respond to the alert with a 'Y', it confirms that the transaction is valid and you can continue to use your card as normal.

  2. For Email Alerts
    You will not be able to respond to the email to resolve the issue; the email will prompt you to contact MBNA Fraud and Security as soon as possible.

How to Identify an MBNA Fraud Alert?

    • MBNA Fraud Alerts text messages will contain specific information to help you identify the transaction, including:
    • Last two digits of your MBNA Credit Card or of your Authorized User's Card; and transaction information, including the $ amount, transaction type and merchant name.
    • MBNA will never ask you to reply to a Fraud Alert text message with any personal information or click on any links in your reply.
    • MBNA Fraud Alerts also use automated voice calls that will prompt you to select certain numbers (ex: 1 or 2) to validate recent activity in question.
    • If you receive a voice alert, you will not be asked to provide any personal information; alerts will always contain detailed information regarding the transactions we would like to verify (ex: $ amount, type, and merchant name).
    • Emails will always include your first and last name, and contain the last 4 digits of your credit card number. The only thing that email alerts will prompt you to do is to contact MBNA Fraud and Security using telephone numbers listed on the MBNA.ca website or the back of your card.
    • MBNA Fraud Alert Emails will not include or ask you to click on any links to confirm activity.
