About this product
The full CMS NPPES registry — every individual and organizational NPI in the United States — loaded into consistent, queryable tables. All registry fields are preserved: provider names, credentials, taxonomies and specialties, practice and mailing addresses, other identifiers, and deactivation records. No API rate limits, no bulk-file parsing — just the registry, ready for SQL.
Refreshed as NPPES publishes, with full batch lineage so every record traces to its source release. Built for teams that want the unmodified source registry as their foundation — provider directories, credentialing pipelines, claims enrichment, and network analytics.
Need validation and enrichment on top? The NPPES Provider Golden Record adds USPS-validated addresses, duplicate resolution, PECOS enrollment, OIG exclusion flags, geo-enrichment, and FHIR R4 resources on the same weekly cadence.
Questions it answers
