A system and method for providing broadcast messages to message specific broadcast target areas having a broadcast admission control module receiving records each having a broadcast message, a message specific broadcast target area, and a broadcast message originator identifier for each one broadcast message, validating each received broadcast message record as a function of the broadcast message originator identifier and the broadcast target area, and generating a validated broadcast message record for each successfully validated broadcast message record. The system includes a broadcast message distributor module receiving the validated broadcast message records, determining for each message record which message broadcast transmission network provides broadcast messaging service to at least a portion of the broadcast target area and transmitting each broadcast message and all or a portion of the broadcast target area, over an output interface coupled to the determined broadcast transmission network.
