NPPES
National Plan and Provider Enumeration System — the CMS system that assigns NPIs to eligible individuals and organizations. The NPI is an intelligence-free administrative identifier and a join key only where another source supplies it; it does not establish licensure or credentialing. The production table's newest system date was June 10, 2026 when checked July 12, 2026; no source-release date was present in that query. 8.9M rows · Historical catalog reference: May 2026. Reference date 2026-06-10; historical loaded-system observation; not a source-release or current-freshness claim.
