Tools / NPI lookup
The registry, one field at a time.
Search NPPES by NPI, or by last name and state, and read the record back.
Live query against the NPPES public registry, maintained by CMS. Enumeration data only — an NPI records who was issued an identifier, not whether their credentials were ever verified.
What an NPI proves
An identifier, not an authenticator.
An NPI says a number was issued. It does not say the person using it today is the person it was issued to.
