Abstract: The present invention provides systems, methods and computer program products for authorizing transactions based on, at least in part on, enhanced authorization data. In one embodiment, enhanced authorization data is received in a request for authorization to accept a transaction instrument as payment. Examples of enhanced authorization data include an automatic number identification, an information identifier, an email address, a contact telephone number, a ship-to-name, ship-to-address, an Internet Protocol address, and a seller identification. A risk analysis is performed based, at least in part, on the enhanced authorization data to determine the risk of the request being associated with a fraudulent purchase. The risk may be calculated by comparing the enhanced authorization data with information stored about the transaction instrument or with historical transaction information.
