Overview
An address history is the list of places a person has lived, arranged in time. In employment screening it functions less as a finding than as an instrument. Very little on a background report depends on where somebody lived. A great deal depends on knowing where to look, and the address history is what determines that.
It reaches the report by two routes that are easy to conflate. The applicant supplies one version on the application. A database search supplies another. Neither is authoritative on its own, and the timeline a screening company actually works from is built by reconciling the two.
Two Sources, One Timeline
| Applicant supplied | Listed on the application or authorization form, usually covering a set number of years. Reflects what the person remembers and chooses to write down. |
| Database derived | Returned by a search against commercial records, most often as part of an SSN trace. Reflects what businesses reported, with no input from the applicant. |
Each source covers what the other misses. An applicant knows about the year spent in a friend’s apartment where no account was ever opened in their name. The databases know about a billing address attached to a store card the applicant forgot about a decade ago.
Neither list is complete, and working from one alone produces a narrower search than the record supports.
Where the Database Records Come From
The primary source is credit header data, the identifying block that sits above the financial detail in a credit file. Our SSN Trace & Validation page describes that source and its limits in full.
Screening companies commonly supplement it with:
- Change of address records filed with the postal service
- Utility, telecom, and other account records held by data aggregators
- Public records that carry an address, including property records, court filings, and in some states voter registration files
Two limits apply to all of it. Motor vehicle records are governed by a separate federal privacy statute and are not a general purpose source for this. More importantly, every one of these sources records an address that was reported to a business, not an address a person was verified to occupy. A mailing address, a billing address, and a residence are three different things, and the data does not reliably distinguish them.
Why the Timeline Drives the Rest of the Report
Criminal records in the United States sit in individual courts, mostly at the county level, and no complete national index is available to employers. A criminal search therefore has to name the jurisdictions it will cover, and the address history is what names them.
The relationship is direct. Each place on the timeline becomes a court to search, which means an address missing from the timeline is a court nobody searched.
The timeline also determines:
- How many searches are ordered, which drives both cost and turnaround time.
- Which state level repositories are worth running, since those are organized by state rather than county.
- Whether an international search is needed at all.
This is also why turnaround varies so widely between candidates. A person who stayed in one county for 15 years needs a single search. A person who moved six times across four states needs several, and each one runs at the speed of the court it queries.
How Far Back It Goes
Seven years is the usual span, and no law requires that figure for address history specifically. The convention is borrowed. Federal law restricts how far back a consumer reporting agency may report most non-conviction and other adverse information, and 7 years is the figure it uses. Criminal searches are commonly scoped to match, so an address list covering the same period lines up with the searches it feeds.
Other spans are used. Ten years is common for positions carrying heightened requirements, and some roles are scoped to an applicant’s entire adult history. The span is a policy decision rather than a legal ceiling.
Gaps in the Timeline
Gaps are common, and the possible explanations are numerous:
- Living with family or a partner without holding any account in one’s own name
- A period spent outside the United States
- Military service, where an assigned address may not resemble a residential one
- A stretch without stable housing
- Ordinary recall failure across a long span
- A young applicant with little reported history of any kind
Because the causes vary this widely and the underlying data is incomplete by design, a gap is a prompt to ask rather than a conclusion to draw. The standard handling is to ask the applicant to account for the period, then scope the searches to whatever that produces.
When the Two Lists Disagree
Disagreement between the applicant’s list and the database list is the normal case, not the exception.
| An address on the report the applicant did not list | A billing address, a relative’s address, forwarded mail, a co-signed account, or a data entry error at a reporting business. |
| An address the applicant listed that does not appear | No account was ever opened there. Common with short stays, sublets, and shared housing. |
| Overlapping date ranges | A mailing address and a residence running at the same time, or a lag between a move and the first business that reported it. |
| An address in a state with no apparent connection | A mixed file, a common name, or a transposed digit somewhere in the chain. |
The usual practice is to search every credible address from both lists rather than choose between them, which errs toward a more complete search. A discrepancy is not by itself a finding about the applicant. Where one does contribute to a decision, it goes through the required notice process rather than being treated as settled.
Addresses Outside the United States
The commercial databases behind an address history are domestic. Someone who lived abroad shows what looks like a gap even when their history is complete and accurately reported.
This matters beyond the appearance of it. Criminal and other records covering that period exist in another country and require an entirely different search, obtained under that country’s rules. Our International Screening page covers how those records are reached.
The same applies in reverse to anyone who arrived in the United States recently. A short domestic address history reflects the length of the domestic record and nothing else.
What an Address History Does Not Establish
An address history is not residence verification. It records addresses that were reported to businesses. It does not confirm that a person lived at any of them, and it is not evidence of when they arrived or left.
- It is not a credit check. The financial portion of a credit file is a separate product, covered on our Credit Reports page.
- It returns no criminal records. It tells the criminal search where to go.
- It is not complete. An address absent from the report means nothing was reported, not that nobody lived there.
- Its dates are approximate. They mark when an address was reported, not when a person moved.
Where It Fits Under the FCRA
When a screening company compiles an address history for employment purposes, it forms part of a consumer report. Written disclosure and authorization are required before the report is requested, accuracy obligations attach to the information reported, and the individual has the right to dispute anything incorrect. Our FCRA Overview covers those requirements in full.
Where an address discrepancy contributes to a decision not to hire, the required notice steps apply, which exist so that a reporting error can be corrected before the decision becomes final. See The Adverse Action Process.
State law adds further requirements in some places. Our State Laws Overview covers how the states differ and links to the current position for each one.
