Abstract: Techniques for identifying a target individual's or entity's current address are disclosed. An initial query/search on the target is performed to identify previously reported addresses of that target. This initial query specifies information known about the target (e.g., target's name, along with city and/or state in which the target is to believed to reside). The initial query attempts to match the specified target information to existing entries in a database storing previously reported addresses. Any target matches resulting from this initial search are presented to the user. Target matches selected for verification contain previously reported addresses associated with the target match. Each of these previously reported addresses are then queried into a database storing high-confidence records (e.g., public utility records). If a previously reported address is verified as being the current mailing address, then that address (or its corrected version) is reported to the user.
