Archiving mobile device contact information as a function of occurrence of one or more temporal conditions is provided herein. By way of example, contact information stored in an active contact list of a mobile device can be associated with a temporal condition, such as frequency of use, or location of the mobile device, or the like. If the temporal condition is met, the contact information is archived at remote data store and/or passive portion of mobile device memory. Once the temporal condition is no longer met, the contact information can be re-downloaded into active memory and incorporated into the active contact list. As a result, aspects of the claimed subject matter provide for organizing a mobile device contact list according to temporal condition(s) to provide added efficiency and to manage such information according to a determinable situational context.
