Real Estate & Home Services

A list of owner names is only useful if you can reach the people on it. The People Search API matches names to current person records and returns phone numbers, emails, addresses, and owned property records so teams can connect with more of the right owners.

Use cases: Match names from owner lists / Reach absentee owners / Confirm results with ownership context

Financial services, legal, insurance, and client-record workflows

Teams that manage client, case, member, or policyholder records use People Search API to turn incomplete names into more current contact records and keep work moving when information goes stale.

Use cases: Record maintenance / Contact refresh / Prioritized follow-up using confidence signals

Recruiting & Staffing

Recruiting and staffing teams use People Search API to turn candidate names into more reachable contact records by adding direct phone numbers, emails, and confirming which person record is most likely the right one.

Use cases: Match thin inputs / Augment contact information / Resolve common-name ambiguity

Fraud and risk workflows

Fraud and risk teams use People Search API to compare a submitted name against returned contact and identity signals and use those signals alongside the rest of their data to support broader review workflows.

Use cases: Person lookup / Confidence-signal review / Consistency checks

Whitepages Pro API returns identity signals for use in your own workflows. It is not an FCRA-regulated product and is not intended for credit, underwriting, employment, housing, insurance, or other FCRA-covered decisions.

How is Whitepages Pro API different from other people search APIs?
