Why Whitepages Pro for People Search

Most people search APIs are built on aggregated, licensed, or scraped sources, with quality that varies record by record. Whitepages Pro is built on something different: 28 years of US identity resolution and tens of millions of monthly consumer searches on Whitepages.com. That foundation shapes how Identity Graph resolves ambiguity. When two people share a name, when an address has multiple residents, when a record could refer to either of two relatives, Identity Graph uses proprietary signals to determine which match is most likely current and correct.

Built for the Industries That Need to Find the Right Person

Real Estate · Home Services · Insurance · Staffing & Recruiting · Legal · Healthcare

Real Estate & Home Services

A list of owner names is only useful if you can contact the people on it. The Whitepages Pro people search API matches owner names to current person records and returns phone numbers, emails, addresses, and owned property records. So you connect with more of the owners on your list.

Match the names: Match names from your list to current person records, with match confidence scores
Reach absentee owners: Return phone numbers, emails, and addresses for owners who don't live at the property
Confirm by ownership: Check owned property records tied to owners, so you have the right people

Recruiting & Staffing

Names from sourcing or referral lists don't tell you how to contact the people behind them. The Whitepages Pro API matches candidate names to current person records and returns emails, cell numbers, and addresses, so you reach candidates on the phone numbers and emails they actually answer.

Match thin inputs: Match candidate names to current files, even with just a city or state
Augment contact info: Append your records with additional cell numbers and emails to improve your ability to reach candidates
Common names: Use addresses and match confidence scores to confirm you have the right person

Fraud Teams

The Whitepages Pro people search API matches names to person records and returns phone numbers, addresses, emails, and confidence scores. Use these signals alongside the rest of your data to help make a fraud determination.

Person lookup: Match the names people give you to the contact information associated with them
Confidence signals: Feed match confidence scores into your scoring model
Consistency check: Compare returned phone numbers, addresses, and emails against what's already in your data

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

What Customers Are Saying

Higher Match Rates

"In recruiting, finding the right person is the only thing that matters. We tried a lot of competitors, and in our testing, other providers matched only 50% of the people we wanted to reach. With Whitepages, we're getting hits in far more cases."

– Javier Llevada, WISBE Healthcare Recruiting

More Accurate and Easy to Use

"We tested the Pro API head-to-head against competitors for homeowner and resident data. It was no contest. Whitepages is more accurate and far easier to use. No double or triple querying just to get what you want."

– Reinhard Otto, Infinium Realty

Critical for Customer Outreach

"Our financial services clients move or change numbers leading to inaccurate data. Whitepages API enables us to keep contact data current which is critical to our business."

– Josh Millang, Retired Protected · Financial Services

What data does the People Search API return?

Names and aliases, current and historical addresses, phone numbers (mobile, landline, VoIP) with confidence scores, email addresses with confidence scores, property ownership, job title, and employer.

Is Whitepages Pro available outside the US?

No, Whitepages Pro returns U.S. data only. The API is intended for U.S. identity and contact workflows.

How is Whitepages Pro priced? Is there a free trial?

Pricing is self-serve. You can start a free API trial or purchase a monthly or annual plan (with a 15% annual discount) online with no sales call required. Plans are tiered by volume and may be cancelled or upgraded at any time.

How easy is it to get started?

Most users are up and running in less than an hour. Sign up online, receive your API key, and start sending queries through the API or MCP server. You can also connect through workflow automation tools like Make or n8n.

Can I integrate the API with my CRM and AI workflows?

Yes. The Whitepages Pro People Search API uses standard RESTful endpoints and returns structured JSON, so it fits into CRMs, recruiting platforms, and AI pipelines. Connect through the Whitepages MCP server for agentic AI workflows in tools like Claude and Cursor.

What else can I do with the Whitepages Pro API?

The same API powers other capabilities:

Reverse Phone API – Match a phone number to its owner and return name, address, email, and line type
Property Data API – Match a property to its owner, occupancy, contact details, mortgage information, and property details
