What you can do with this workflow

Complete the record

Start with the person record you already have and fill in missing contact information — phone numbers with line type, emails, and addresses.

Keep it current

Refresh stale records with the phone numbers, emails, and addresses on file today, so you're reaching people where they are now.

See how strong each match is

Returned records include confidence scores that help your team rank, filter, and decide what to act on first.

You are in the right place if

  • Your team works from records that lose value when phone numbers, addresses, or other contact details change.
  • You need to keep reaching clients, customers, members, prospects, or case contacts over time.
  • You want to reduce the manual work involved in tracking down current contact information.
  • You need a way to prioritize returned matches rather than treat every result as equally useful.
  • You are supporting a recurring workflow, not just occasional one-at-a-time lookups.

Common record-maintenance workflows

Different teams describe the work differently, but the underlying problem is the same: records go stale, outreach breaks, and someone has to restore contactability.

Financial advisors

Keep client records current so outreach and service workflows do not stall.

Legal teams

Support case and client communication when contact information changes over time.

Insurance and public adjusters

Improve reachability across ongoing claim, service, or policyholder workflows.

Healthcare-related and senior living workflows

Support recurring contact workflows where current information matters to ongoing operations.

Member and customer operations

Keep prospect, customer, or member records more actionable as data changes.

How it works

1

Start with what you have

Use Person Search when you have a name, phone number, email, or address and need current contact information for that person.

2

Get back what's current

Matching person records come back with phone numbers, emails, and addresses. Use confidence scores to decide how results are treated in your process.

3

Put the results to work

Send the results into your CRM, internal tools, or outreach process, so keeping records current doesn't depend on manual searches.

Endpoint for contact data lookups

FAQs

What can I start with for this workflow?

Start with any piece of the contact record — name, phone number, email, or address. Search with the fields you trust and leave out anything that might be stale, since every input you add narrows the match.

How does the Whitepages Pro API help keep records current?

The API fills in what's missing and replaces what's stale. Start with the record you have, and get current phone numbers, emails, and addresses, with confidence scores to prioritize what to act on first. Your contact records stay current inside the systems your team already uses.

What data does the API return for a contact data lookup?

Person Search returns phone numbers with line type, email addresses, current and historical addresses, and property ownership. You also get confidence scores on person matches, phone numbers, and emails. Not every field returns for every query, so the fastest way to see what you'll get is to use the free trial to test your own records.

How should I use confidence scores?

Confidence scores help you prioritize matches and decide what to review or act on first. They are a signal, not a guarantee, and should be used inside your own workflow rules.

Can the Whitepages Pro API support outreach across large record sets?

Yes. The API is built for recurring use at scale — run entire record sets through your own system, with plans sized to your monthly queries. Custom plans are also available for higher volumes.

Is Whitepages Pro API U.S.-only?

Yes. Whitepages Pro API returns U.S. people and property data only.

Can I use this for employment, housing, underwriting, or insurance decisions?

No. Whitepages Pro API is not an FCRA-regulated product and is not intended for credit, underwriting, employment, housing, insurance, or other FCRA-covered decisions. The API returns identity signals for you to use in your own workflows.

How do I start testing the API?

Start with the free 14-day trial — no credit card required. You get access to the full API suite and the same data as paid plans, so you can run the lookups you'd actually make and see exactly what you'd get in production.
