A computing system can receive a pick-up request for a transport service from a requesting user within a given region. Based at least in part on the requesting user being within the given region, the computing system can transmit match code data corresponding to a match code to the computing device of the requesting user. The computing system may then receive input data indicating the match code from a computing device of an available driver, signifying that the available driver is to provide the transport service for the requesting user, and update a status for the requesting user to indicate that the transport service is being provided by the available driver for the requesting user.
