A communications addressing system includes first and second communication devices. The first device is capable of at least sending a message using a system specific transmission protocol. The message has a content portion and an addressing portion. The addressing portion includes a unique identifier of an identified receiving entity. An entity identification system provides a least one communication link for a system specific transmission protocol which is derived from the unique identifier of the receiving entity. A security filter screens messages sent to the identified receiving entity. The second communication device is capable of at least receiving a message using at least one system specific transmission protocol. When a sending entity transmits a message using the unique identifier to the entity identification system, it will determine a communication link for at least one system specific transmission protocol for the identified receiving entity and transmit the message through the security filter.
