A system for providing a mobile application includes a Mobile Subscriber Detection Authorization and Verification System (MSDAVS), to request and receive confidential information from a confidential information owner relating to a user who opted-in to a mobile service application, and to communicate the received confidential information to a mobile application service provider. The MSDAVS can include an opt-in database, to store opt-in or registration data of the opted-in users of the mobile service application and a service policy database. The mobile application service can be a mobile traffic alerting service, the confidential information owner a telephone number database of one of a wireless carrier or a telephone number database operator, and the requested confidential information a list telephone numbers of opted-in users in an alert area, defined by the mobile traffic alerting service.
