You can contact Mastercard customer service by calling (800) 627-8372. You can also visit Mastercard's website and select the bank or credit union that issued your card to find contact contact information for its customer service department. Alternatively, just call the number on the back of your card.
Mastercard is not a credit card issuer, so for specific account inquiries, you'll have to reach out to your card's issuing bank or credit union directly.
