An immediate alert notification system via wireless tethered devices is provided. The system comprises a processor, a memory, and an application stored in the memory that when executed on the processor receives a first message from a first mobile device. The system also determines that the first message indicates that a slave device is within range of a first master device associated with the first mobile device. The system also determines that the slave device is not associated with the first master device and is associated with a second master device and determines that the slave device was previously reported as lost. The system also sends a second message to a second mobile device associated with the second master device, the second message advising that the slave device has been located and further providing recovery information for the slave device.
