Find US Healthcare Providers & Medical Specialists by NPI

Across the United States, NPPES lists 7,411,289 active individual NPI records (Type 1, individual practitioners) and 1,958,206 active organization NPI records (Type 2: hospitals, clinics, pharmacies, labs, suppliers and other organizations) with a US practice address. In the 50 states and DC, with a population of 334,922,499 residents (ACS 5-year 2020-2024), that is 2,198 individual NPI records per 100,000 residents. An NPI record shows registration in NPPES; it is not a state license and does not show that a provider currently practices.

Of the states with population data, District of Columbia has the highest rate, 6,934 practitioners per 100,000 residents, and Puerto Rico the lowest, 1,265 per 100,000.

High-density metropolitan corridors support extensive medical subspecialization, while rural states increasingly leverage primary care networks and virtual consultation options to meet healthcare demand.
