Search providers
How search works
- What it searchesThe 7,327,918 individual records in the CMS NPPES registry, file of Aug 9, 2026: by the start of the last name, or by one exact 10-digit NPI.
- More filtersThe NPI lookup also takes a first name and a state, and searches organizations.
- Before you rely on a resultNPPES records are updated by providers themselves, so an address or specialty can lag. Confirm the license with the state board search.
- PrivacyQueries are processed on the server and are not attached to any account; PlainDoctor has no accounts.
