A system can receive a request for service from the computing device of a requesting user of the users of the network service and select a driver to provide the service for the requesting user. The system transmits an invitation to the computing device of the selected driver to facilitate the request, and transmits a first set of data to the computing device of the requesting user or the selected driver. The first set of data enabling the computing device of the requesting user or selected driver to output an ultrasonic signal. The system then receives a second set of data indicating that the computing device of the selected driver or the user detected the ultrasonic signal. Based on receiving the second set of data, the system verifies that a rendezvous between the requesting user and the selected driver has occurred.
