Through our rules, we provide direction for business and operational efficiencies to our customers and other participants in our network. This module explains rules and standards, why we have them and the principles that they support.
Rules impacting processors and retailers
As a Mastercard processor or retailer, 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 Web site 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.
