Running a background check on someone usually means gathering what is already public about them and putting it in one place. You can do a lot of this yourself with free tools, or you can use a search service that pulls the same kinds of records automatically. This guide explains how the process works, what you can reasonably learn, and the limits you need to understand before you start.
What a background check actually is
In everyday language, a background check is just structured research about a person. The information comes from public records, online profiles, and data that has leaked from past breaches. None of it is secret. You are not hacking anything or pulling a credit file. You are collecting scattered details that are already accessible and connecting them to a single individual.
The accuracy of the result depends on how common the person's name is, how much they share online, and whether the records are current. A check on someone with a rare name and an active online presence will look very different from one on a person who keeps a low profile.
Public records
Public records are the backbone of most searches. 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 confirm where someone has lived, whether they own a home or business, and whether they have appeared in civil or criminal court. They will not tell you anything an agency did not record, and they can lag behind real life by months or years.
Social profiles
Social media and other public profiles fill in the human side. A person's accounts can reveal their employer, hometown, interests, photos, and the people they associate with. Usernames are useful here: the same handle often appears across many platforms, which lets you tie accounts together.
Profiles are easy to find but easy to misread. People use nicknames, set old accounts to private, and share things that are out of date or simply not true. Treat what you find as a lead to verify, not as proven fact.
Breach and leak data
Over the years, large amounts 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 belongs to a real person, link an email to a phone number, or surface accounts someone forgot they had.
Revealer's dataset draws on more than 21 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.
What a search can and cannot tell you
A good search can establish identity, contact details, likely locations, public affiliations, and a general picture of someone's online footprint. It is genuinely useful for reconnecting with someone, checking that a person is who they claim to be, or understanding who you are dealing with before a meeting or a transaction.
It cannot read minds or predict behavior, 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
This is the part that matters most. 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, a background check is a fast way to confirm who someone is and gather the public information attached to their name, email, or phone number.
Getting started
You can do this research manually, but it is slow and easy to get wrong. If you want to skip the legwork, enter a name, email, or phone number on our background check page and let the search pull connected public records and breach data for you.
