There are three main types of sources: Deed, COA (change of address), and new phone/utility connects. The Deeds come directly from 3,100+ courthouses as soon as a home purchase is recorded. COAs are self-reported and come from publication subscriptions and private customer files. New phone and utility connect come from telephone and utility companies. We currently have 20 sources included in our new mover and new homeowner database, which we receive daily or weekly.
