Type 1 vs Type 2 NPI: individual vs organization

Updated 2026-07-19

Every NPI is one of two entity types. The distinction matters because it changes what information the registry holds and how the provider appears on claims.

Type 1 — Individual

A Type 1 NPI belongs to a single human provider. The record carries their name, credentials (like MD or DO), gender, and taxonomy — the code for their specialty. Sole proprietors are individuals who bill under their own name.

Type 2 — Organization

A Type 2 NPI belongs to a business: a group practice, hospital, clinic, or pharmacy. Instead of a personal name it carries a legal business name and an authorized official — the person who registered it. Big systems often enumerate subparts, each with its own Type 2 NPI.

Why a provider might have both

A physician who owns their practice may have a Type 1 NPI for themselves and a Type 2 NPI for the practice entity. On this site you can tell them apart at a glance — each profile is labeled Individual or Organization. Browse providers by state to see the mix in your area.

Frequently asked questions

Can one person have both a Type 1 and Type 2 NPI?

Yes. A provider who practices as an individual has a Type 1 NPI, and if they also incorporate (for example, a solo practice LLC) that business can have its own Type 2 NPI.

What is an organization subpart?

A large organization can enumerate subparts — for example, individual departments or locations — each with its own Type 2 NPI, so claims can be attributed correctly.
