CLETS and NLETS messages are classified according to their destination, as follows:
Point-to-Point Messages - these are single address messages directed specifically to another agency;
Joint Messages - these are multiple address messages directed to two or more agencies;
CLETS Area Bulletins - these are messages sent to one or more of three broadcast areas within California;
many agencies do not participate in the bulletin service. It should not be assumed that a message addressed to a bulletin area will be received by all agencies within that area. If a message is thought to be of specific interest to one or more agencies within a bulletin area, a point-to-point administrative message should also be sent;
NLETS State APBs - these are messages sent to one or more (maximum of five at one time) areas within the Continental United States;
NLETS National APBs - these messages are sent to all states within the continental United States;
NLETS APB messages are first sent to the state control agency within the state to which the message is addressed. The state control agency may or may not rebroadcast the message to other agencies within their state. If a message is thought to be of specific interest to one or more agencies within the APB area, a administrative point-to-point message should also be sent to the agency or agencies.
