Peking_Duck: As I'm sure you know, these AMBER Alerts aren't issued in high frequency—as with any sort of alert system, the more it's used, the more desensitized people become, which defeats its purpose as alerts are ignored.
WEA alerts are marked by the outgoing agency to be received in specific areas/cities via individual cell towers (ie, if there were to be a large emergency affecting only El Cajon, an alert could be issued from only cell towers in El Cajon)—thus they are geographically-specific.
The alerts do not discriminate with regard to phone numbers. Any and all equipped phones within range of the towers will received the alert, even if the phone is from out of state. The manner in which they are sent is similar to broadcast radio and television: one-way signals receivable by all—thus individual phones are never tracked.
