Type 1 vs Type 2 NPI: what is the difference?

Type 1 vs Type 2 NPI: what is the difference?

A Type 1 NPI identifies an individual health care provider, while a Type 2 NPI identifies an organization such as a practice, hospital, or other eligible entity. The distinction describes the enumerated entity type in NPPES. It does not determine licensure, ownership, Medicare enrollment, organizational relationships, or provider quality.

Scope and material limitation

What this answer covers

This comparison is limited to NPPES entity types. One individual can be associated with organizations, but those relationships are separate source facts.

Source-snapshot manifest receipt

Reproducible lineage, explicitly unsigned

This receipt attests the source snapshot manifest, not any individual fact.

The answer-series chain record is unsigned. It does not authenticate a person, organization, eligibility state, or individual fact.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
