Protecting you

If you believe a transaction posted to your account is fraudulent, you should immediately contact the financial institution that issued your card. Look for a customer service number on the back of the card or on your billing statement. You can also contact the Mastercard Assistance Center toll-free at 1-800-Mastercard (1-800-627-8372) or collect from outside the U.S. at 1-636-722-7111. If you’re in the U.S., you can report scams and suspicious calls, emails, texts and websites to the Federal Trade Commission.

Mastercard appreciates your diligence in protecting your finances. While we take each card breach very seriously and are working closely with investigative agencies, we encourage you to contact your financial institution for the most up-to-date information. Typically, there is a customer service number on the back of the card that you can call.

Please be advised that Mastercard does not contact individuals to request personal information including account information. If you receive an unsolicited phone call, email, text message or social media request from an individual claiming to be a Mastercard representative: Do not respond. If you have questions or concerns about your account, contact your financial institution directly by calling the number on the back of your card or billing statement.
