Abstract: While various communication systems permit one-on-one communication between users, it is difficult to contact multiple users at a time with little hassle. The personal notification and broadcasting system provides a solution for contacting a plurality of contacts in emergency and non-emergency contexts. The system receives a call from a caller attempting to reach the plurality of contacts. The system compares an identifier associated with the caller to identifiers stored in a database to authenticate identity of the caller.

In some embodiments, the system retrieves from a database stored contact information for the identified contacts. The system contacts the identified plurality of contacts and selects an action to take (e.g., arranging a conference call, broadcasting a message from the caller, etc.
