Mastercard headquarters is at 2000 Purchase Street in Purchase, New York, a suburban campus about 30 miles north of Manhattan. Before you dial, one fact saves most callers time: Mastercard does not issue cards, hold accounts, or set your interest rate — the bank whose name is on your card does. Below you will find the verified corporate office address, the official Mastercard Global Service numbers for the U.S. and abroad, every other support channel the company publishes, and the escalation steps that actually work when a dispute stalls.

Mastercard Headquarters Location and Contact Information
Mastercard Incorporated lists 2000 Purchase Street, Purchase, NY 10577 as its principal executive office on its most recent quarterly report to the SEC (the 10-Q for the quarter ended June 30, 2026), and the same address appears as the Global and North America Headquarters on the company’s own global locations page. Mastercard owns the building — a three-story, I. M. Pei-designed campus originally built for IBM in the 1980s — and has been headquartered there since the mid-1990s, so unlike some corporate giants there is no recent move to worry about. The corporate switchboard is (914) 249-2000.
The Purchase campus is an executive and administrative office, not a customer service center. Nobody there can look up your balance, reverse a charge, or reissue a card, because Mastercard does not hold cardholder accounts at all. In Mastercard’s own words, it “does not issue cards, extend credit, determine or receive revenue from interest rates or other fees charged to account holders.” Your issuing bank — the institution named on the front or back of your card — owns the account relationship, and its number on the back of the card is almost always the right first call. Use the corporate address for written escalations and formal correspondence, not for day-to-day account questions.
Phone Contacts
Mastercard publishes only a small set of consumer phone numbers, all of them on its official U.S. support page. The support page does not state operating hours, so plan on the issuing bank’s number for anything urgent that involves your specific account.
- Mastercard Global Service (U.S.): 1-800-627-8372 (1-800-MASTERCARD) — lost or stolen card reporting, emergency card replacement, general help and card benefits questions
- Calling from outside the U.S.: +1-636-722-7111 — collect calls accepted, according to Mastercard’s FAQ
- Corporate switchboard (Purchase, NY): (914) 249-2000 — headquarters reception; not a customer service line
- Operations center (O’Fallon, MO): (636) 722-6100 — office switchboard; not a customer service line
- Media inquiries: Mastercard lists its press contacts by region and topic on its media contacts page; these lines are for journalists only
Customer Service and Support Channels
Beyond the phone, Mastercard’s main consumer channel is the Ask Mastercard web form. It covers transaction disputes, fraud reports, Mastercard SecureCode, card benefits, lost or stolen cards, currency conversion, prepaid and gift cards, phishing reports and general account inquiries. The form asks for the first six digits of your card number (the bank identification number, which tells Mastercard who issued the card) and the merchant name involved, so have both ready. Mastercard says it will reply by email.
The company’s FAQ page repeats the same advice for most account questions: PIN problems, ATM fees, declined cards, and billing issues all go to the financial institution that issued your card, whose contact details are on the back of the card and on your statement. Mastercard’s own online tools are the ATM locator, the currency converter, and the card benefits guides for protections such as zero liability and ID theft protection. On social media, Mastercard posts corporate news from @MastercardNews on X and the MasterCardUS page on Facebook; these are marketing channels, so never share card numbers there. One practical tip: if a merchant charge is wrong, start a dispute with your issuer right away — the chargeback clock runs from the transaction date, not from when you first call Mastercard.
Company Background
Mastercard traces its roots to 1966, when a group of U.S. banks formed the Interbank Card Association to compete with BankAmericard (today’s Visa). The network was branded Master Charge in 1969 and renamed MasterCard in 1979. Mastercard International Incorporated, the operating subsidiary that still runs the network today, was formed in November 1966 as a Delaware membership corporation owned by its member banks. The modern parent, Mastercard Incorporated, was created as a Delaware corporation in May 2001, absorbed Europay International in 2002, and went public on the New York Stock Exchange in May 2006, converting from a bank-owned association into a shareholder-owned technology company.
Today Mastercard describes itself as a technology company in the global payments industry. According to its 2025 annual report, the network operates in more than 220 countries and territories and more than 150 currencies, switched 175.5 billion transactions in 2025, and carried $10.6 trillion in gross dollar volume. Net revenue for 2025 was $32.8 billion. The company employed approximately 39,800 people at the end of 2025, roughly 70 percent of them outside the United States. Its stock trades on the NYSE under the ticker MA.
Leadership
Michael Miebach has been President and Chief Executive Officer since January 2021. He joined Mastercard in 2010 to run the Middle East and Africa region, served as Chief Product Officer from 2016 to 2020, and became President in 2020 before succeeding Ajay Banga as CEO. Sachin Mehra is Chief Financial Officer. Because both the parent and the operating subsidiary are Delaware entities, their registrations can be looked up through the state registry; our Delaware business search guide explains how. The headquarters itself is registered to do business in New York, and our New York business search guide covers that lookup.
Key Office Locations
Purchase is the official home, but the network itself runs from Missouri. Mastercard’s principal technology and operations center sits at 2200 Mastercard Boulevard in O’Fallon, a St. Louis suburb, and the company owns that campus as well; the 10-K calls it the “principal technology and operations center,” and it is where the company’s largest U.S. tech hub is based. The international collect number, +1-636-722-7111, carries the O’Fallon area code for that reason. Mastercard also lists a Kansas City office at 11530 NW Ambassador Drive. If you need to verify a Missouri registration, see our Missouri business search guide.
In New York City, Mastercard’s Tech Hub occupies 150 Fifth Avenue in the Flatiron District (phone (917) 408-2775), housing product, engineering and research teams plus a customer Experience Center. Other U.S. offices on the company’s locations page include 123 Mission Street in San Francisco and 4250 North Fairfax Drive in Arlington, Virginia, near Washington. Regional headquarters are in Miami (801 Brickell Avenue, for Latin America and the Caribbean), Dubai (Dubai Internet City, for the Middle East and Africa), and Toronto for Canada, alongside regional bases in Europe and Asia Pacific. Mastercard’s newsroom also highlights technology hubs in Dublin and St. Louis.
Dealing with Customer Complaints
Start with the issuing bank, not Mastercard. The bank on your card owns the account and is the only party that can open a dispute, issue a chargeback, refund a fee or investigate fraud; call the number on the back of the card, note the date and the representative’s name, and ask for a case number. If the bank does not resolve the problem, contact Mastercard Global Service at 1-800-627-8372 or through the Ask Mastercard form — Mastercard can explain network rules such as zero liability and can intervene on card-benefit claims — and put a written summary in the mail to Mastercard Incorporated, 2000 Purchase Street, Purchase, NY 10577.
Credit and debit card accounts are regulated financial products, so you also have a federal route: file a complaint with the Consumer Financial Protection Bureau. The CFPB forwards complaints to the card issuer, which must respond, typically within 15 days, and this step frequently unsticks a billing dispute that has gone quiet. If money is still on the line after that, check the arbitration clause in your cardholder agreement — most U.S. card agreements require arbitration for larger claims — and remember that small-claims court remains available for modest amounts.
Summary
Mastercard’s headquarters is at 2000 Purchase Street, Purchase, NY 10577, with its technology and operations center in O’Fallon, Missouri. For a lost or stolen card or general help, call Mastercard Global Service at 1-800-627-8372 in the U.S. or +1-636-722-7111 collect from abroad; for anything involving your balance, charges or PIN, call the issuing bank on the back of your card; and use the CFPB when a dispute stalls.
