NPI Discovery Intelligence
Everything you need to know about healthcare provider identification.
What is an NPI Number?
An NPI (National Provider Identifier) is a unique 10-digit identification number issued by the Centers for Medicare & Medicaid Services (CMS) to every healthcare provider in the United States. It is required for all HIPAA-standard electronic transactions and serves as the universal identifier for physicians, nurses, dentists, therapists, hospitals, and other healthcare organizations.
Is the NPI Lookup tool free to use?
Yes. The MedicalProspects NPI Discovery Engine is completely free and requires no account or login. Anyone can search the NPPES registry by NPI number, provider name, medical specialty, or organization name directly from the tool.
What search modes does the NPI Discovery Engine support?
The tool supports three search modes: NPI Lookup (enter a 10-digit NPI number for a direct match), Individual Provider Search (search by name, medical specialty with autocomplete, and state or city), and Medical Institution Search (search healthcare organizations and facilities by name and location).
How current is the NPPES data in this tool?
The NPI Discovery Engine is indexed from the official CMS NPPES April 2026 dissemination dataset. This includes active individual providers (Type 1 NPI) across all clinical specialties and geographic locations in the United States.
Can I get verified email addresses and phone numbers for NPI-identified providers?
Yes. The NPPES registry contains practice addresses and public phone numbers, but not direct emails or mobile numbers. MedicalProspects enriches this data with verified direct emails, mobile numbers, and CRM-ready contact datasets. Use the request form on any search results or provider profile page to submit a data request — the team responds within one business day.
Does each provider have their own profile page?
Yes. Every provider in the registry has a dedicated profile page accessible at a permanent URL based on their NPI number (e.g., medicalprospects.com/tools/npi-lookup/provider/1234567890/). Profile pages display the provider's clinical specialty, entity classification, practice addresses, public contact information, and NPPES registry status.
