Restoring Family Links (RFL) is a continuous and ongoing program of the Red Cross and Red Crescent Movement, National Society involving activities that aim to prevent separation and disappearance, look for missing persons, restore and maintain contact between family members and clarify the fate of persons reported missing. The most common situations where the Family Links Network takes action are when loss of contact is due to armed conflict or other situations of violence; natural or man-made disaster; migration and in other situations of humanitarian need, such as allowing detainees to keep in touch with their families while in prison. RFL services are free of charge. Nepal Red Cross use all possible means to search for the person, including going to the last known address, contacting families, neighbors of the sought person, visiting displaced people and refugee camps, consulting institutions, the authorities or other organizations, broadcasting names of sought persons through the media etc. When a large-scale emergency occurs, online tracing is also possible.
