The present invention is directed to methods for a called party to report unwanted telephone calls to jurisdictional authorities. These calls may be unwanted, unlawful, or other calls. In the methods of the present invention, the called party dials a code comprised of a series of digits, which triggers the switching node associated with the called party to generate a series of messages, at least one of which encompasses the originating telephone number of the unwanted call. At least one of the messages is directed to the proper reporting authority such that the called party reports the unwanted event. Called parties can take further actions, such as including additional messaging or blocking subsequent calls from the calling party number. The reporting authority can take further action as well, such as matching the called party number with subscriber or geographic information.
