NPI Guide is an independent U. S. healthcare provider directory designed to help people find doctors, clinics, hospitals, pharmacies, and other healthcare professionals.

Users can search by provider name, specialty, city, ZIP code, or National Provider Identifier (NPI), or browse listings by provider type, state, and major city. The directory covers more than 9. 3 million active provider records across nearly 38,000 cities, including specialists in mental health, nursing, dentistry, rehabilitation, vision care, and many other fields.

Listings may include addresses, phone numbers, specialties, and, where available, official CMS quality ratings. NPI Guide says its provider records come from the monthly public NPPES data file published by the Centers for Medicare & Medicaid Services, while quality ratings are sourced from CMS Care Compare. The site is not a government website and is not affiliated with or endorsed by CMS or other government agencies.

It cautions that an NPI record does not establish that a provider is licensed, credentialed, or currently practising, and advises users to verify details independently
