You can access your Mastercard account online or by phone through your credit card issuer, or you can contact Mastercard for assistance. Keep in mind that Mastercard doesn't issue credit cards, so you can't log in to any existing credit card account via the Mastercard website or its consumer support department. They're only designed to connect you with your card's issuer, which can then give you access to your specific Mastercard account.
Ways to Access a Mastercard Credit Card Account
Online through the issuer's website. Log into your account on the issuer's website or mobile app with your user ID and password.
By calling your card issuer. Call the phone number on the back of your card to reach the issuer's customer service department.
Via the Mastercard website. Visit the Mastercard Consumer Support website. Select your credit card's issuing bank from the dropdown menu and click "Go."
By calling Mastercard. Call Mastercard Consumer Support at 1 (800) 627-8372. Press "1" for billing and account info, then enter your Mastercard credit card number. You will be transferred to the issuer's customer service line.
Once you've accessed your Mastercard account by phone or online, you can schedule a payment, view current or past statements, and redeem rewards. You can also review account information, such as your current statement balance, minimum payment amount, payment due date, credit limit, available credit, and more. Some card issuers will allow you to chat with a customer service representative online, too.
