AI summary
An NPI number is a ten-digit National Provider Identifier assigned through CMS's NPPES system to enumerated health care providers. Individuals receive Type 1 NPIs and organizations receive Type 2 NPIs. The identifier remains attached to the NPPES record, but it does not establish licensure, Medicare participation, credentials, or service quality.
Each receipt below describes its exact retained artifact or live source. Dates and digests never cross artifact boundaries.

Scope and material limitation
This answer is limited to NPI enumeration and public NPPES data. It does not merge a source record with unrelated people or organizations on name alone.
Dated source facts
Source-snapshot manifest receipt
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.

Limitation: NPPES is provider-reported enumeration data. An NPI does not establish licensure, Medicare enrollment, identity beyond the published record, or quality.

Frequently asked questions
What’s on file, by the numbers
Platform snapshot · 2026-07-27
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.
