A location is specified, e.g., a current location of a mobile device or a user-specified location. A representation of the location is represented on a map displayed by the mobile device. A set of contacts having a corresponding address in proximity to the location is determined. A graphical representation of the set of contacts is provided on the map proximate to the one or more corresponding addresses. If the location is a current location of a mobile device, the map can be updated in response to the current location changing with a representation of an updated current location and a representation of an updated set of contacts.
