Systems, methods, and computer program products are provided for processing a request relating to a mobile device. A request, including a mobile device identifier and a partner system identifier corresponding to the partner system, is received from a partner system via a communication network. An authorization procedure is executed based on the mobile device identifier and the partner system identifier. The authorization procedure includes determining whether a partner system account list, associated with the mobile device identifier, includes the partner system identifier. Authorization of the request is granted if the partner system account list includes the partner system identifier; and is denied if the partner system account list does not include the partner system identifier. A response to the request is transmitted to the partner system via the communication network, based on a result of the authorization procedure.
