Address history refers to a chronological record of physical locations where an individual has resided over a given period of time. In private investigation, it is compiled through database searches, public records, and open-source research to establish where a subject has lived, for how long, and in what sequence. It is commonly used as a foundation for locating individuals or verifying identity.
An address history is essentially a timeline of everywhere a person has lived, often going back several years or even decades. During an investigation, this record helps a PI confirm that someone is who they claim to be, track down a current address, or identify associates connected to past residences. Think of it as a map of a person's residential footprint over time.
A client attempting to serve legal documents on a defendant who has moved without notice may need an address history to locate the individual's current residence. Families attempting to reconnect with a lost relative, or attorneys verifying the last known location of a witness before trial, also commonly request this type of research. In civil litigation, an address history can help establish whether a party was reachable at a specific location during a relevant time period.
Licensed investigators typically compile address history using lawful sources such as public records, commercial databases, and open-source information. Access to certain records, including utility accounts, private financial records, or protected government databases, is not available to private investigators without lawful authority, regardless of the purpose of the investigation. If an address history is being compiled as part of a consumer report, such as for tenant screening or similar purposes, the Fair Credit Reporting Act may apply and governs how that information is obtained and used.
How long does it take to receive an address history report, and what format will the results be in?
A basic address history compiled from commercial databases can often be returned within one to two business days, though more thorough research involving public records or document retrieval may take longer. Results are typically delivered as a written report listing addresses in chronological order, along with associated dates and, where available, source information. The depth and turnaround time depend on how much verifiable information exists for the subject and the scope of research requested.
Are there any limitations on how far back an address history can go, or gaps I should expect in the results?
The completeness of an address history depends heavily on how consistently a person's residences were tied to documented records such as property filings, voter registration, or credit activity, and gaps are common, particularly for individuals who rented informally or moved frequently. Commercial databases aggregate data from multiple sources but are not always current or complete, and investigators cannot guarantee that every address will be captured. In some cases, additional investigative steps such as interviews or field research may be needed to fill in missing periods.
