Abstract
A system and method for providing early warning notifications to telephone subscribers having calling number delivery service. The system uses an advanced intelligent network to initiate several calls in rapid succession to all calling number delivery subscribers located within a pre-determined geographic area. A code identifying the disaster warning message is transmitted to the subscribers'"'"' calling number delivery systems in place of an actual calling line identification. Subscribers having calling name delivery service receive the disaster code and a text message briefly describing the disaster warning.
