NPI Registry Lookup: US Healthcare Provider Data

Unofficial tool. Not affiliated with, endorsed by, or sponsored by the Centers for Medicare & Medicaid Services (CMS) or the U.S. Department of Health and Human Services.

Search the NPPES NPI Registry and export US healthcare providers as one row per NPI. It's for healthcare staffing and credentialing teams, health-tech and billing companies, payers, pharma and device sales operations, and researchers.

Input: NPI numbers, or a search by specialty, provider or organization name, city, state and ZIP code.

Output: NPI, provider type, name and credential (or organization name), status, enumeration and last-updated dates, primary specialty with license state and number, all specialties, primary practice address, phone and fax, other practice locations and a link to the registry page.

Confirm at npiregistry.cms.hhs.gov before relying on any record. Registry data is self-reported by providers and can change.

NPI lookup input

• npiNumbers: 10-digit NPIs, up to 1,000 (check digit validated)
• taxonomyDescription: specialty in NPPES taxonomy wording, e.g. Family Medicine, Internal Medicine, Dentist, Pharmacy
• firstName, lastName, organizationName: a trailing * matches a prefix
• city, state, postalCode
• enumerationType: any (default), individual or organization
• maxResults: up to 10,000

State or provider type alone is too broad for the NPI API: add a specialty, name, city or ZIP. The API returns at most 1,200 providers per search, so narrow by city or ZIP for larger pulls.
