Frequently Asked Questions

Where does public records data come from?

Public records are generated and maintained by government entities at the county, state, and federal level. Court filings, arrest logs, property transfers, and death records all become part of the public record. People-search services aggregate this legally available information from those official sources.

Why do search results vary so much by county?

Records in the United States are primarily maintained at the county level. Counties differ significantly in how much they digitize, how far back records go online, and what they make accessible without a formal records request. A county with a modern court portal may have decades of filings online. A smaller county may require an in-person visit for the same information. The state and county guides on this site explain these differences for each jurisdiction.

What records are most useful when searching for a specific person?

It depends on what you are trying to confirm. Court records are often the most reliable for establishing location history. Arrest records and criminal records are useful when the goal is a broader public-safety picture. For identity confirmation, address history and relative connections are usually the fastest starting points.

Can I use these searches for jobs, housing, or insurance decisions?

No. The services discussed on this site are not consumer reporting agencies and the information they provide is not a consumer report. They should not be used for employment, tenant screening, insurance underwriting, credit, or any other purpose regulated by the Fair Credit Reporting Act.
