DHS/USCG/PIA-021 Rescue 21

Rescue 21 is the United States Coast Guard’s (Coast Guard) advanced command, control, and direction-finding communications system. Rescue 21 replaces the National Distress and Response System and was created to accurately locate mariners in distress and save lives and property at sea and on navigable rivers. Rescue 21 also has a sub-system titled, Digital Selective Calling (DSC), which uses a Maritime Mobile Service Identity (MMSI) number to associate the boat owner and his or her location and contact information for automated distress calls. This Privacy Impact Assessment (PIA) is being conducted because Rescue 21 collects and uses personally identifiable information (PII).
