Our databases are primarily derived from "public Data" sources. Public Records are information that’s freely available from local, county, state and federal government entities. Then Again the federal government doesn’t make it easy for the average person to get entry to these Data.
Generally you would need to go to their workplace in person and request the Data. Imagine seeking to monitor somebody down that lived in CA and having to move to each (and even just 3) county court properties. We work with the quite a lot of executive entities to buy their Information and put them into our large databases.
