A device provides for display, to a first user device, information associated with a potential contact, and an option to communicate with the potential contact. The device receives a selection of the option from the first user device, and obtains, based on the selection, an identifier for a second user device associated with the potential contact. The device provides a communication request and the identifier to a message server to cause the message server to selectively cause a communication session to be established between the first user device and the second user device. An indication that the communication session is denied may be provided to the first user device when the second user device does not accept the communication request. The communication session may be established, without revealing the identifier to the first user device, when the second user device accepts the communication request.
