Disclosed herein are systems and methods for real-time provisioning of new card numbers to users of a consumer computing system. A consumer computing system (“CCS”) may have servers and databases situated within a banking infrastructure in order to provide various features to users via a software application executed by a client device. The software application may interact with the CCS servers, such that the CCS servers and the software application offer the client device and the user certain features not ordinarily available in conventional banking infrastructures. These features may include the real-time provisioning of card numbers for a user's banking account. In operation, the client device may submit a request for a new card number to a CCS server, which may be generated in real-time and active in the payment stream when the card number is generated.
