Merchants that accept credit cards and debit cards are assigned a merchant category code (MCC) by the payment networks based on the kinds of products and services they sell. Online and mobile merchants use merchant codes and/or other identifying information that we rely upon to identify them as a qualifying online or mobile merchant. While these identifiers are generally reliable and accurate, there are times when an online or mobile merchant uses a merchant code that does not properly identify themselves. Green Dot Bank does not determine which MCC a merchant chooses to classify itself as and has no way of changing a merchant's identifying information that we receive during the authorization and posting process. Therefore, some online or mobile purchases may come across as some other type of non-qualifying transaction. While we strive to make sure we are accurate and inclusive of all the major online and mobile merchants, there could be times when a transaction is coded incorrectly by the merchant and cash back is not applied. When this happens, Green Dot will not be able to apply the 2% cash back for that transaction. Additionally, we are not able to provide cash back on airline tickets or on products and services that are redeemable for cash, like gift cards, online funding of accounts, credit card cash advances, P2P funding, prepaid cards, money orders, traveler's checks and similar products or merchants that primarily sell cash services.
