Each 406 MHz beacon is programmed with a unique fifteen-character identification (ID) code.  This ID is transmitted as part of the distress signal when a beacon is activated.  As long as the beacon has been registered with Indian MCC (INMCC), the contact information helps Rescue Coordination Centers quickly confirm that the distress is real, who they are looking for and where they should look.  Up to date beacon registration is a vital part of providing a rapid response to distress incidents as well as mandatory by regulations here in India. Beacons can be registered or information updated by mail, fax or online.  There is no charge for registration.  See the ISTRAC website (www.istrac.org/inmcc) for information on registering your beacon.
