NPI Lookup: NPI Registry Search for US Healthcare Providers

Look up US healthcare providers and organizations in the official CMS NPPES NPI Registry. Give NPI numbers, provider names (Last, First) or organization names and get clean records: NPI, name, credential, primary specialty and taxonomy, license, practice location, phone, status and last-updated date. Export JSON, CSV or Excel.

Use cases

• Healthcare data teams: validate and enrich NPI columns in claims, referral or credentialing files.
• Billing and compliance: confirm a provider's NPI is active and matches name and specialty.
• Researchers: pull specialty and location data for a list of organizations.
• AI agents: fast structured provider lookups via API or MCP.

How it works

1. Each NPI number is looked up directly; names and organizations use the registry search.
2. The official NPPES NPI Registry API (v2.1) is queried; nothing is scraped.
3. Records are flattened into one row per provider or organization.
4. Name searches return up to maxPerQuery records per query; each record returned is one billed event.

Input

{
  "queries": [
    "1003000126",
    "Mayo Clinic"
  ],
  "state": "",
  "maxPerQuery": 3
}

Empty input {} runs a small demo. Other options: state, maxPerQuery, maxResults, concurrency.

Example output

Real output from a default run (some fields omitted for width):

npi	type	name	status	primarySpecialty	city	state
1003000126	individual	ARDALAN ENKESHAFI	active	Hospitalist	BETHESDA	MD
1881018208	organization	MAYO CLINIC	active	Clinic/Center, Multi-Specialty	ROCHESTER	MN

Every run also produces a ready-made table view in the Output tab, and you can export to JSON, CSV or Excel.

Pricing

FAQ

Is this legal? The NPI Registry is public data that CMS publishes through its free public NPPES NPI Registry API, and this Actor queries that API directly with an identifying User-Agent and a short delay between requests (default 200 ms). Data is provided as-is and may be out of date; verify critical details with CMS or the NPPES registry itself. This Actor is not affiliated with or endorsed by CMS.

Does it return patient data? No. Only provider and organization registry entries, which are public by design.

Is this for sending bulk outreach? No. It is for lookup, validation and research. If you contact anyone you must follow CAN-SPAM, TCPA and other applicable laws.

Are failures charged? No. Errors and queries with no match are not charged.

Limitations

Data is only as current as the NPPES registry; NPIs are US-only; name searches return at most 200 records per query.
