- [NPPES NPI Registry (search one provider)](https://npiregistry.cms.hhs.gov/)

Source: [CMS NPPES NPI files](https://download.cms.gov/nppes/NPI_Files.html). Public domain (U.S. government work, released by CMS under FOIA). Rows are as providers entered them in the CMS NPPES register: an NPI is enumerated when a provider applies, and NPPES does not check a license. The specialty is the provider's primary taxonomy code in the words of the NUCC code set; the group is NUCC's grouping. Organizations are named with their authorized official's title only. Pages show the city and state; the full practice address and phone are in the list.
