The different illustrative embodiments provide a method, system, and program product for dynamic changes to a user profile based on external service integration. The method, system and program product comprise establishing a direct two-way communication between a first mobile device and a second mobile device when a first mobile device direct transceiver and a second mobile device direct transceiver are within a range of each other. A number of data is gathered from a number of internal sources or a number of external sources. An analysis of the number of data to determine a modification to a first list stored in the first device is performed. A modified first list is generated based on the analysis. The modified first list is automatically sent from the first mobile device to the number of second devices responsive to establishing the direct two-way communication between the first mobile device and a number of second devices.
