A method and system for providing cross-carrier contact information for mobile users of mobile communication devices and other mobile communication devices provides a single registry of user profiles, wherein each user profile is established and maintained by a user so that each user may control how and by whom they are contacted. The registry of user profiles may be accessed with a client software application on a calling party's mobile communication device. The calling party may transmit a look-up request to the registry over a data channel. The registry receives the look-up request and locates a user profile that matches the look-up request and provides the user profile to the calling mobile communication device. The user profile does not display the mobile communication device number for the called mobile communication device. Once the calling party calls the called party, the called mobile communication device may query the registry and display the user profile for the calling mobile communication device.
