A first user device associated with a first dependent user may receive a request to add a second dependent user associated with a second user device to a contacts list of the first user device, and may provide a first device identifier, identifying the first user device, to the second user device via a short-range communication. The first user device may receive, from the second user device, a second device identifier, identifying the second user device, via a short-range communication, and may provide the second device identifier to an approval system. The first user device may receive, from the approval system, an indication of approval to add the second dependent user to the contacts list, and may add the second dependent user to the contacts list based on the indication. The first user device may communicate with the second user device, via a telecommunications network, based on the contacts list.
