Public records — court filings, business registries, property and voter data — are among the most authoritative open sources there are, because they're created by institutions rather than self-reported. Combined with data-broker aggregators, they let you build a grounded picture of a person. This method does it accurately and within the rules.
What you'll need
- The person's name and at least one anchor (a city, an employer, or an approximate age)
- People and company sources from the People & company category
- Aggregators and record tools from the Data acquisition category
Steps
- Anchor the identity first. Common names produce dozens of matches. Fix on one person early using a location, workplace, or age, and carry that anchor through every source so you don't merge two people.
- Start with authoritative registries. Business registries, court dockets, and property or licensing records are primary sources — prefer them over aggregators, which repackage and sometimes garble the same data.
- Use data brokers as a lead, not a truth. People-search aggregators are useful for generating leads — relatives, past addresses, phone numbers — but their data is frequently outdated or wrong. Treat every field as a hypothesis to confirm at the source.
- Pivot between records. A company filing names a director; the director's address appears on a property record; the property links to another entity. Follow the chain, checking each hop.
- Watch for name collisions. Before you attach a record to your subject, confirm the anchor still matches. Two people with the same name in the same city is common and the fastest way to a false conclusion.
- Mind the law and the purpose. Public-records research is regulated for uses like employment and tenancy screening, and privacy law varies by country. Know your legal basis before you start.
Common pitfalls
- Merging two people. The single biggest error in people research; keep your anchor visible at every step.
- Trusting aggregators. Broker data is stale and error-prone — confirm at the primary record.
- Ignoring the rules. Some jurisdictions and use cases restrict this sharply; check before you act.
Verify your result
You have researched the person when your picture rests on primary public records, each tied to the same anchored identity, with data-broker leads confirmed at the source rather than taken on trust.
