Systems and methods are provided for provisioning data based on network messaging. One exemplary method includes passing, by a network computing device, a message to an institution where the message includes an account identifier for an account of a user and data of a first party. The data of the first party includes a code associated with a category of the first party and/or an identifier of the first party. The method also includes detecting, by a computing device, the message based on inclusion of the account identifier in the message and retrieving a control for the user based on the account identifier. The method then includes identifying, by the computing device, data for the user to be shared with the first party based on the data of the first party satisfying the control and sharing the identified data with the first party apart from the network computing device.
