A proximity alert system tracks geographic locations of riders and drivers using global navigation satellite system receivers in their mobile devices or in a device such as a beacon or dashcam. The proximity alert system compares the location data received from the riders' and drivers' devices and determines whether a service-requesting user is within a threshold distance of one of the driver devices that does not belong to the driver assigned to provide transport service for the rider. If so, the proximity alert system can communicate a notification message to the rider to confirm whether the rider is in the correct car. The proximity alert system can also communicate a message to the driver asking the driver to double-check the identity of the rider.
