About State-Filtered NPI Lookup
The NPPES NPI Registry contains over 8 million active provider records across all 50 US states and Washington DC. State-filtered searches help narrow results when you are verifying providers who practice in a specific state. Each state page displays provider-specific information including state medical board contact details, approximate provider counts, major healthcare systems, and links to state-specific resources. For state Medicaid enrollment verification, see our Medicaid NPI Lookup tool.
Why State-Level NPI Verification Matters
Healthcare providers must be licensed in the specific state where they practice. An NPI record confirms federal registration but does not verify state licensure — that must be checked separately with the state medical board. When credentialing a provider, always verify: (1) NPPES NPI registration (this tool), (2) state medical board license status, (3) Medicare PECOS enrollment if applicable, and (4) state Medicaid enrollment if applicable. Our cross-lookup tools cover each of these verification steps.
