NPI Registry Search - US Doctors, Dentists & Healthcare Providers

Search the official NPPES NPI Registry (run by CMS, the US Centers for Medicare & Medicaid Services) and get clean, ready-to-use rows for doctors, dentists, nurse practitioners, therapists, pharmacies, clinics and hospitals: specialty, license number, practice address, phone, fax, mailing address, other names and NPI status.

Search by specialty (taxonomy), city, state, ZIP code, first/last name or organization name, or paste a list of NPI numbers to verify and refresh. $2 per 1,000 providers. No API key, no login, no scraping - the data comes straight from the government's public API.

What you can use it for

• Healthcare lead lists - every dentist in Austin, every cardiology practice in a ZIP code, every pharmacy in a state (split by city or ZIP).
• NPI verification - check that a list of NPI numbers is valid and active, and pull the current name, specialty and address.
• Provider directories and credentialing - license numbers and states per specialty, organization names and "doing business as" names.
• Market sizing - count providers per specialty and area.
• Data enrichment - add phone, fax and practice address to a CRM that only has names or NPIs.
• AI agents - one tool call through the Apify MCP server answers "find me pediatric dentists in 10001".

Pricing

$2 per 1,000 providers ($0.002 each) plus a tiny actor start fee ($0.00005).

Providers	Cost
100	$0.20
1,000	$2.00
10,000	$20.00

You pay only for providers returned. Searches with no results, invalid or unknown NPI numbers and registry errors are free (they appear as rows with an error field). Set "Maximum cost per run" and the actor stops cleanly when it is reached.

Getting more than 1,200 providers

The NPI Registry API returns at most 1,200 records for a single search. For big areas, split the search: list the ZIP codes of the city in "ZIP codes" (one search per ZIP), or run one search per specialty. The log warns you when a search hits the 1,200 cap.

FAQ

Where does the data come from? The NPPES NPI Registry API (npiregistry.cms.hhs.gov), the official public source. Providers update their own records, so lastUpdated tells you how fresh each row is.

Does it include emails? No. The registry does not publish email addresses. It does publish practice phone and fax numbers.

Is this legal to use? CMS publishes NPI Registry data openly (NPPES data dissemination) for anyone to look up and download. Follow the usual rules for any outreach you do (e.g. TCPA for calls and texts).

Can I search by taxonomy code? Search with the description (Pediatric Dentistry); each row returns the codes.
