Summary
NPPES NPI Registry is a free public directory of active National Provider Identifier records for health care providers and health plans. Users can search by NPI number or type, taxonomy, provider and organization names, authorized official, location, postal code, and address type. CMS offers access through a web search, an API, and downloadable files. The search page shows at most the first 2,100 records, and hourly query limits apply; bulk queries must use the DDS file. Downloadable ZIP files include reference files for other names, practice locations, and endpoints. As of March 3, 2026, Version 1 monthly and weekly files are no longer supported, and Version 2 is recommended. The listed September 14, 2026 monthly Version 2 file is 1,105.79 MB. Registry records and downloads are subject to FOIA disclosure, and active records cannot be suppressed or opted out. CMS does not provide technical support for working with dissemination files.
