Indian citizens do not need a passport required for andaman. The islands belong to India and the domestic traveling regulations are applicable. Any legitimate government photo identification suffices. Non-citizens of India are, however, required to possess valid passport, Indian visa, and Restricted Area Permit (RAP). The permit is usually restricted entry to tourist sites and the duration is pegged. It is also a good idea to bring the right documents as they are checked in the airports, ports, and hotels.
