Rules impacting processors and merchants

As a Mastercard processor or merchant, you are vital to our success. And that success is better assured if you have access to and understand the Mastercard rules and how they may apply to your business. 

You also should be aware that Mastercard rules and other standards change from time to time. While we always strive to keep the documents on this Web site up to date, it's possible that they will not always be absolutely current in all regards. In the event of any discrepancy between the documents found at this website and those rules and standards Mastercard deems to be the official rules and standards, the official rules and standards will apply.

Feel free to download the official Mastercard rules and other important documents below.
