About NPI Profile
The web’s free NPI provider reference site, powered by connected healthcare data.
NPI Profile is the top reference website for up-to-date NPI information about healthcare providers in the United States. Our free NPI registry search tools run on a complete database built from the official NPPES public file published by the Centers for Medicare & Medicaid Services (CMS) and refreshed every week.
Search the National Provider Identifier database by NPI Number, Doctor Name, Organization Name, Address, City, State, ZIP code, Taxonomy Code, Specialization or Provider Type. Beyond the basic registry record, our knowledge graph cross-references every profile with Medicare PECOS enrollment status, Medicare participation, and Clinical Laboratory Improvement Amendments (CLIA) crosswalk information, so a PECOS lookup, CLIA lookup, or taxonomy code lookup starts from the same place as your NPI search.
Medical billers use these tools to verify claims, credentialing specialists confirm providers, and patients check a doctor’s credentials before an appointment, all at no cost and without an account. NPI Profile is independent and not affiliated with CMS or any government agency; every record comes from official public data releases. Read more about how our data works.

The National Provider Identifier (NPI) is a unique 10-digit identification number issued to healthcare providers in the United States.
