About Mastercard
Mastercard is a global technology company in the payments industry that connects consumers, financial institutions, merchants, businesses and governments through its payment network and related services. Mastercard supports digital payment choices across more than 210 countries and territories and provides technologies designed to make transactions secure, simple, smart and accessible.
Mastercard traces its history to 1966, when a group of banks established the Interbank Card Association to create a shared payment system. Over the following decades, the organization expanded internationally, adopted the Mastercard name and developed into one of the world’s major payment technology companies. In 2026, Mastercard marked its 60th anniversary as a company and 20 years since its initial public offering.
Today, Mastercard’s business extends beyond traditional card payments. Its operations include core payments, commercial and new payment flows, cybersecurity, fraud prevention, data and analytics, consulting, digital identity, real-time payments and other value-added services. Mastercard’s global headquarters is located at 2000 Purchase Street, Purchase, New York 10577, and the company reports more than 30,000 employees across more than 80 offices.

How to Reach a Real Person at Mastercard
The main Mastercard customer assistance number in the United States is 1-800-MASTERCARD (1-800-627-8372). Customers calling from outside the United States can use +1-636-722-7111. These numbers can be particularly useful for Mastercard assistance and lost or stolen card situations. If you need assistance with Mastercard Click to Pay specifically, Mastercard also publishes 1-833-271-9871 and support.checkout@mastercard.com for that service.
However, Mastercard is generally not the financial institution that issued your credit, debit or prepaid card. For account balances, billing questions, interest charges, declined transactions, credit limits, refunds and transaction disputes, call the bank or financial institution listed on the back of your card or billing statement. Mastercard specifically states that only the issuing financial institution has access to the cardholder’s account information and can manage formal transaction disputes.

How to File a Complaint Against Mastercard
Step 1: Identify Who Issued Your Mastercard
Before filing a complaint, determine whether the problem involves Mastercard itself or the bank or financial institution that issued your card. Mastercard provides the payment network, but individual credit, debit and prepaid card accounts are normally managed by financial institutions. Check the front and back of your card and your billing statement to identify the issuer responsible for your account.
Step 2: Contact Mastercard Customer Service
For general Mastercard assistance, call 1-800-627-8372 (1-800-MASTERCARD) in the United States. If you are outside the United States, call +1-636-722-7111. Explain the problem clearly and provide the information needed to identify the service or transaction involved.
Step 3: Contact Your Card-Issuing Bank
For account-specific complaints, contact the financial institution that issued your Mastercard. This includes complaints involving billing, interest, fees, account balances, declined payments and many transaction-related issues. The correct customer service number is normally printed on the back of your Mastercard or on your billing statement.
Step 4: Dispute an Unauthorized or Incorrect Transaction
If you need to dispute a charge, contact your issuing financial institution directly. Mastercard states that only the issuer has access to the information needed to determine your dispute rights and manage the formal dispute process. If the complaint concerns merchandise or services, try contacting the merchant first. If the merchant cannot resolve the issue, contact your card issuer to discuss a transaction dispute.
Step 5: Report a Lost or Stolen Mastercard
If your Mastercard is lost or stolen, contact your card issuer immediately. You can also call Mastercard at 1-800-627-8372 in the United States for 24/7 assistance. Customers outside the United States can call +1-636-722-7111. Mastercard Global Emergency Services can assist qualifying cardholders with lost or stolen card situations.
Step 6: File a Click to Pay Complaint
For a problem involving Mastercard Click to Pay, contact Click to Pay support at 1-833-271-9871 or support.checkout@mastercard.com. Explain the issue and provide relevant information about your Click to Pay profile or checkout problem without sending sensitive card credentials through unsecured communication channels.
Step 7: Submit a Privacy or Data Protection Complaint
For complaints involving Mastercard’s handling of personal information, contact privacyanddataprotection@mastercard.com. Eligible U.S. consumers exercising applicable privacy rights may also call Mastercard’s privacy toll-free number at 1-833-244-4084. Written privacy correspondence can be addressed to the Global Privacy Office, Mastercard International Incorporated, 2000 Purchase Street, Purchase, New York 10577, USA.
Step 8: Escalate a Corporate Complaint
If the issue concerns Mastercard as a corporation rather than an individual bank-issued card account, written correspondence can be directed to Mastercard International Incorporated, 2000 Purchase Street, Purchase, NY 10577, USA. The verified headquarters telephone number is 914-249-2000. Include a clear explanation of the complaint, relevant dates, previous case numbers and copies of supporting documents.
Step 9: Keep Records of Your Complaint
Keep records of telephone calls, case numbers, emails, transaction information, receipts, billing statements and written correspondence. If the complaint concerns a transaction, record the transaction date, merchant, amount and the response received from your issuing bank. Detailed records can make it easier to follow up with the bank, Mastercard or an appropriate regulator if the complaint remains unresolved.
