A background check, in the everyday sense, means gathering what is already public about an identity and putting it in one place. Investigators, fraud and trust-and-safety teams, and people auditing their own exposure do this with free tools, or with a search service that pulls the same kinds of records automatically. What follows is the actual sources (public records, profiles, breach data), what they can support, and the FCRA line you cannot cross.
What a background check actually is
The details come from public records, online profiles, and data that has leaked in past breaches. None of it is secret. You are not hacking anything or pulling a credit file. You are collecting scattered, already-public details and connecting them to a single identifier: a name, an email, a username, or a phone number. A reverse phone lookup or an email search can anchor that as well as a name can.
The accuracy of the result depends on how common the name is, how much has been shared online, and whether the records are current. A search tied to a rare name with an active online presence looks very different from one tied to an identifier that leaves almost no footprint.
Public records
Start with public records. They are slow, messy, and still where most of the hard facts live. These include things like property ownership, court filings, business registrations, marriage and divorce records, voter registration in some states, and professional licenses. Much of this is held by county and state agencies and can be searched directly, though it is spread across hundreds of separate websites with no shared format.
These records can show where an identity has been associated with an address, whether a home or business is owned, and whether a name has appeared in civil or criminal court. They will not reveal anything an agency never recorded, and they can lag behind real life by months or years.
Social profiles
Public social profiles are where an employer, a hometown, and a reused handle show up. Accounts can surface an employer, a hometown, interests, photos, and connected accounts. Usernames matter here: the same handle often appears across many platforms, which is the core of any username search and one of the strongest links in open-source research.
Profiles are easy to find but easy to misread. People use nicknames, set old accounts to private, and post things that are out of date or simply untrue. Treat anything you find as a lead to verify, not as proven fact.
Breach and leak data
Over the years, large volumes of personal data have leaked from hacked companies. This breach data often includes email addresses, phone numbers, old passwords, and the accounts they were tied to. Searching it can confirm that an email is real, link an email to a phone number, or surface accounts an owner forgot they had, which is exactly why checking your own exposure in this data matters as much as any outward research.
Revealer's dataset draws on 38 billion+ records of this kind, which is why a single email or phone number can return connected details that would take hours to assemble by hand. To see where your own identifiers appear, start with a data breach lookup.
What a search can and cannot tell you
A thorough search can establish an identity, contact details, likely locations, public affiliations, and a general picture of an online footprint. Within an authorized investigation, such as fraud prevention, threat intelligence, due diligence you are lawfully entitled to perform, or an audit of your own exposure, it is a fast way to consolidate scattered public data.
It cannot tell you what someone will do next, and it cannot guarantee that any single record is accurate or up to date. Records get out of sync, names overlap, and absence of a record does not prove absence of an event. Always confirm anything important through a second source before you act on it.
The legal limit you must respect
An OSINT and public-records search is not a consumer report under the Fair Credit Reporting Act (FCRA). It is not produced by a consumer reporting agency, it is not verified to FCRA standards, and it may not be used to make decisions about employment, hiring, housing, tenancy, credit, insurance, or any other purpose covered by that law. If you need a background check for any of those reasons, you must use a properly licensed FCRA-compliant screening service instead. Using public-records data for those decisions is against the law and against our terms of use.
Used within those limits, this kind of research is a fast way to gather the public information attached to a name, email, or phone number and to see where those identifiers are exposed.
Getting started
You can do this research manually, but county sites do not share a format and it is easy to attach the wrong John Smith. If you would rather not click through fifty record portals, enter an email, phone number, username, or name on our background check page and let the search pull connected public records and breach data for you, for authorized research and for checking your own exposure, within the legal limits above.
Frequently asked questions
Can I use this to screen a job applicant or tenant?
No. Results built from public records, profiles, and breach data are not a consumer report under the FCRA, and Revealer is not a consumer reporting agency. Employment, tenancy, credit, and insurance decisions require a licensed, FCRA-compliant screening service.
What records go into a background check?
Property ownership, court filings, business registrations, marriage and divorce records, voter registration where it is public, professional licenses, public social profiles, and breach entries tied to the identifier you started from.
Does it include a credit report or a verified criminal history?
No credit file is involved; you are not pulling one. Court filings can surface where a name appears in public civil or criminal proceedings, but nothing in the result is verified to FCRA standards, so treat it as a lead rather than a finding.
How long does a background check take?
Done by hand, hours to days, because county and state record sites are scattered and each has its own search format. An automated search that matches records across sources for one identifier returns connected results in minutes.
How accurate are the results?
It depends on how common the name is, how current the records are, and how much the person has shared online. Records lag, names overlap, and an absent record proves nothing. Confirm anything that matters through a second source.
Is running a background check on someone legal?
Reading public records is legal. The restrictions sit on use: no employment, tenant, or credit decisions, and no harassment or stalking. Run this kind of research on your own exposure, or on activity you are authorized to investigate.
