StarBus is a cloud-based Bus Ticket Booking System, developed by NIC for Andaman State Transport Service. This eTicketing platform facilitates commuters to book tickets in advance alongside easy cancellation and refund of bus tickets as per their convenience. The app also allows you to check the seat availability to plan the journey with ease. A person can purchase his or her tickets one month prior to the scheduled departure date (excluding date of journey). The bus service seat reservation booking system will close two hours prior to the scheduled departure time and date of the proposed trip. After a successful online transaction, this eTicket will be sent to the email address listed in the passenger's profile during user registration. Passengers can obtain a printout of this eTicket from his or her email or after logging in to his account. The registration is not mandatory and a person can also book tickets as a Guest User. For a Guest User, a valid mobile number is required. On booking the ticket, an SMS is sent to the registered mobile, which can be produced at the time of boarding with valid photo ID proof for traveling.
