What is an NPI?

The National Provider Identifier (NPI) is a unique 10-digit number assigned to every US healthcare provider, both individuals (a doctor, dentist, or nurse) and organizations (a clinic, hospital, or pharmacy). CMS issues it through the National Plan & Provider Enumeration System (NPPES), and it appears on insurance claims and prescriptions. NPIRadar makes that public registry searchable: look up a provider by NPI number, browse providers by specialty, or find providers in your city.
