How To Contact MasterCard

If you need to contact MasterCard, there are three ways to do so.  You can contact MasterCard by calling them on the phone, writing a letter, or sending an email.  Using the phone to call MasterCard is the quickest way to contact the company and resolve an issue, but if there is an issue that a phone call does not resolve, then you can send a message by mail.

To contact MasterCard, you will need:

  • Your MasterCard credit card number
  1. Contact the MasterCard customer service.  Use your phone to dial the MasterCard customer service number, (800) 622-7747 or (800) 627-8372.  
  2. Follow the answering service prompts.  Choose your language to listen to the MasterCard customer service menu.  You can report a lost or stolen card, check your account balance, or request a credit line increase.  If none of the options from the menu works for you, then stay on the line and wait to be connected to a customer service representative.
  3. Talk to the MasterCard representative.  Let the MasterCard representative know what you want and give the representative your card number when asked.  If the customer service representative isn't helpful, then ask to speak to his manager so you can get your issue resolved.
  4. Contact MasterCard by writing a letter.  If calling MasterCard didn't resolve your issue, you can contact MasterCard by writing a letter.  If you write a letter, make sure to include your account information, such as your name, billing address, and card number.  After you finish writing the letter, send it to:
