About NPI Profile

An independent, free reference for National Provider Identifier data, Medicare enrollment, and healthcare provider information across the United States, online since 2015.

What Is NPI Profile?

NPI Profile is a free, publicly accessible reference site for National Provider Identifier (NPI) information about healthcare providers in the United States. Following the adoption of the NPI Final Rule in January 2004, every healthcare provider covered under HIPAA was assigned a unique 10-digit NPI by the NPI Enumerator as the standard identifier for all administrative and financial healthcare transactions.

NPI numbers are issued and maintained by the National Plan and Provider Enumeration System (NPPES), operated by the Centers for Medicare & Medicaid Services (CMS). Provider data is made publicly available under the Data Dissemination Notice, which governs disclosable provider information under the Freedom of Information Act (FOIA).

NPI Profile aggregates and publishes this public data alongside additional CMS datasets including Medicare PECOS enrollment records, CLIA laboratory crosswalks, and Medicare Part D prescription data. The result is a single, searchable reference that gives providers, medical billers, credentialing specialists, and researchers a comprehensive view of any enrolled healthcare provider in the country, all at no cost and without requiring an account.

Who Runs NPI Profile

NPI Profile is an independent, privately operated website. It has published periodical NPPES updates since July 2015. NPI Profile is not affiliated with, endorsed by, or connected to the Centers for Medicare & Medicaid Services, NPPES, or any other government agency, and it is not the official NPI registry.

The site is supported by advertising. There are no accounts, subscriptions, or paid tiers, and provider data is never sold. Every record shown here is already public under the NPPES Data Dissemination Notice; NPI Profile organizes it so it is easier to search, compare, and cite.

How Our Data Works

NPI Profile is a third-party aggregator of public government data. We do not generate, modify, or independently verify individual provider records. Here is how the data flows from the source to what you see on this site:

Data Sources and Update Dates

Each dataset on NPI Profile comes from a named public source and carries the date of the release currently loaded.

Accuracy, Corrections, and Removal

Because our records come entirely from the official NPPES public release, we cannot manually edit, correct, or remove individual provider records. If your information on NPI Profile is incorrect, the fix is to update it directly in NPPES at nppes.cms.hhs.gov. The correction will appear on NPI Profile automatically after CMS publishes the next weekly update.

If something on this site does not match the NPPES record it came from, for example a mapping or display error, report it through the Contact page and we will correct the presentation. We do not change the underlying data.

If you would like your profile removed from NPI Profile specifically while keeping your official NPPES record intact, use the NPI Profile Opt-Out tool.
