Source and limitations
Results come from the CMS NPPES public registry. Its fields are submitted administrative records and can lag later changes. An NPI identifies a record; it does not establish licensure, qualifications, or clinical quality.

NPI lookup questions
What is an NPI number?
An NPI is a 10-digit National Provider Identifier issued by CMS through the National Plan and Provider Enumeration System (NPPES). Type 1 NPIs identify individual clinicians and Type 2 NPIs identify organizations. The identifier is administrative: it does not establish licensure, qualifications, or clinical quality.
Is an NPI the same as a medical license?
No. NPPES is an administrative registry, and an NPI record does not establish licensure, qualifications, or clinical quality. License status is issued and maintained by each state licensing authority, and NPPES does not carry it. Treat an NPI record and a license record as separate documents.
How do I look up a provider by name?
Enter a clinician's first and last name, or an organization name, and this page queries the public CMS NPPES registry directly. Name searches can return multiple candidate records; each result lists the NPI, listed entity type, taxonomy, and available location fields. A 10-digit NPI returns one exact record.
How often is NPPES data updated?
CMS publishes NPPES dissemination files on weekly and monthly cadences. This page queries the live CMS NPPES registry API at request time, and Fonteum's loaded NPPES data showed 2026-06-10 as its newest record system date — a dated production observation, not a CMS release date.
Is every healthcare provider listed in NPPES?
No. NPPES lists only providers and organizations that have applied for and received an NPI. HIPAA-covered providers must obtain one, but some practitioners who never bill electronically may not appear. An absent record is a statement about this registry, not a conclusion about the subject.
