What is Type 1 vs Type 2 NPI?
Type 1 NPIs identify individual healthcare providers (physicians, therapists, nurse practitioners), while Type 2 NPIs identify healthcare organizations (hospitals, group practices, clinics, pharmacies).

Type 1 vs Type 2 NPI Explained
CMS assigns two types of NPI numbers through NPPES. Type 1 (Individual) NPIs go to sole practitioners and individual providers, regardless of whether they practice alone or as part of a group. Type 2 (Organization) NPIs go to healthcare organizations including hospitals, group practices, home health agencies, pharmacies, and other entities.
A single physician working at a hospital will have their own Type 1 NPI, while the hospital has a separate Type 2 NPI. The physician uses their Type 1 NPI on claims for services they personally provide, and the hospital uses its Type 2 NPI for institutional billing. Some providers who are sole proprietors may have both a Type 1 and Type 2 NPI.
For B2B data targeting, the distinction matters because your sales strategy differs based on whether you're selling to individual practitioners or to organizations. Medical device reps often need both: the organization NPI to identify the facility, and individual NPIs to identify the decision-makers within that facility.
Why Type 1 vs Type 2 NPI Matters for Healthcare Data
Knowing whether you need Type 1 (individual) or Type 2 (organization) NPIs determines how you structure your provider data. Selling to physicians requires Type 1 records with individual contact details. Selling to hospitals or group practices requires Type 2 records with organizational data and decision-maker contacts.
Real-World Example
A healthcare staffing agency needs to contact hospital administrators about travel nurse placements. They need Type 2 NPI records (organizations) filtered to hospitals, with enriched contact data for hiring managers. Pulling Type 1 individual physician records would give them the wrong audience entirely.
Frequently Asked Questions
Can an individual provider have both Type 1 and Type 2 NPI?
Yes. A sole proprietor who operates their own practice can have a Type 1 NPI as an individual provider and a Type 2 NPI for their practice entity. This is common among solo practitioners.
Which NPI type should I use for provider data targeting?
It depends on your sales motion. If you sell to individual physicians or clinicians, use Type 1. If you sell to hospitals, clinics, or group practices, use Type 2. Many teams need both: Type 2 to identify target organizations, then Type 1 to find the decision-makers inside them.
How many Type 1 vs Type 2 NPIs exist?
As of 2026, there are roughly 6.5 million Type 1 (individual) NPIs and 1.5 million Type 2 (organization) NPIs in NPPES. Not all are active practitioners; many belong to retired providers whose NPI records remain in the system.
