A system for providing management of contact records includes a single record that is primarily indexed by phone number. The contact records are network accessed through any of various cellular and data networks by various devices and cached locally on such devices by way of permission from the owner of each record. In this way, the owner of each record has the ability to later deny access for any other user to some or all of the information stored in the contact record. As changes are made to a contact record, all others users having access to that contact record receive updated information. Duplicates are eliminated as no two individuals or establishments share the same phone number.
