Abstract: A method and a system for allocating a vehicle to a passenger is provided. A booking request for booking a ride is received from a passenger device of the passenger. Based on the booking request, a first message is transmitted to the passenger device that indicates a confirmation of the booking request without allocating any vehicle to the passenger. The first message includes a code for pairing with one of vehicles in a queue at a pickup area. The passenger provides the code to a driver of a first vehicle from the vehicles in the queue, when the passenger is at the pickup area. The code is received from a driver device of the first vehicle. The code is validated, and the first vehicle is allocated to the passenger for the ride based on successful validation of the code.
