State Licensing

State Professional Licensing & Disciplinary Records

U.S. state professional-licensing boards · Tier-1 · research-only (never on individual profiles)

Research-only
Source:State Licensing·Snapshot May 2026Open official source ↗

Primary-source professional license rosters and disciplinary actions published directly by state licensing boards. Fonteum holds 7,853,561 license records across four states (Illinois 3,845,349 · Washington 2,422,615 · Colorado 1,566,603 · Connecticut 18,994) and 128,342 disciplinary actions across four (Illinois, Washington, New York, Colorado), spanning five distinct jurisdictions in total.

What Fonteum uses it for

How this source shows up on Fonteum.

Aggregate state-credentialing research and a future 'licensed/sanctioned-anywhere' screen that complements the federal exclusion ring — a provider sanctioned by a state board can look clean on the federal LEIE. The /data and /sources pages report record counts and per-state coverage only; no licensee is named on these catalog surfaces.

What this source does NOT mean

A state license record is a board administrative record, not a Fonteum quality assessment, and a disciplinary action is a board enforcement event, not editorial judgment. The public extracts are name- and license-number-keyed and carry no NPI, so a license never attaches to a federal provider identifier here — the entity-graph cross-link is deferred. Coverage is five states only; absence of a record is not an assertion that a provider is unlicensed.

What this dataset answers

Research and data questions this source supports.

  • 01Size the population of state-licensed professionals across the covered states and compare licensing volume between boards.
  • 02Build a state-credentialing screen that complements the federal exclusion ring — a provider sanctioned by a state board can look clean on the federal LEIE.
  • 03Research the volume and mix of state disciplinary actions across Illinois, Washington, New York, and Colorado.
  • 04Study state coverage gaps in public license data as a precursor to a 'licensed-anywhere' provider check.

Limitations

What we can’t infer from this source.

  • Coverage is five states only (IL, WA, CO, CT licenses; IL, WA, NY, CO disciplinary) — not a national license registry.
  • Name- and license-number-keyed with no NPI; the entity-graph cross-link to federal provider identifiers is deferred.
  • Disciplinary action dates are board-reported and not always present or clean; 97,832 of 128,342 disciplinary records carry a parsed action date.
  • Each state board publishes under its own open-records terms; reuse rights vary by state and are not the uniform federal public-domain footing.
  • Aggregate-only on these pages — no licensee is named on the /data or /sources surface.

Tier

Tier-1 · research-only (never on individual profiles)

Refresh cadence

Per-state — each board republishes on its own cycle (Socrata extracts, bulk rosters, or generated files). Fonteum re-pulls and attests per state.

License

State public records. Each state board publishes its license roster and disciplinary actions under its own open-records terms; reuse rights vary by state. Attribution required: 'Source: {State} licensing board · Snapshot {YYYY-MM-DD}'. License ↗

ToS & usage notes

What the source allows.

State public records published directly by each licensing board (Illinois IDFPR, Washington State Department of Health, Colorado DORA, Connecticut Department of Public Health, and the New York disciplinary roster). Reuse terms are set by each state and vary; this is not the uniform 17 U.S.C. § 105 federal footing. Fonteum attests each per-state snapshot to the 14-tuple provenance contract.

Frequently asked

Common questions about State Licensing.

What is the state professional licensing and disciplinary dataset?
It is primary-source data published directly by state licensing boards: rosters of issued professional licenses and records of board disciplinary actions. Fonteum ingests each board's public extract, attests it to the provenance contract, and reports aggregate counts. It is a board administrative record, not a Fonteum quality rating.
How many records does Fonteum hold and which states are covered?
As of the 2026-06-15 snapshot Fonteum holds 7,853,561 license records across four states — Illinois (3,845,349), Washington (2,422,615), Colorado (1,566,603), and Connecticut (18,994) — plus 128,342 disciplinary actions across four states: Illinois (89,120), Washington (21,640), New York (8,997), and Colorado (8,585). Five distinct jurisdictions are represented in total.
Can I look up an individual provider's license on this page?
No. This page is aggregate-only — it reports record counts and per-state coverage and never names a licensee. The data is name- and license-number-keyed and carries no NPI, so a license is not tied to a federal provider identifier here. For an individual license status check, use the relevant state board's own public search.
Why does the data only cover a handful of states?
Only a minority of state boards publish bulk-downloadable license and disciplinary data; most are lookup-only portals. Fonteum has onboarded the states with clean bulk or structured public extracts first. Coverage is five jurisdictions today and absence of a record is not an assertion that a provider is unlicensed.
How can I cite this data?
Cite the specific state board with the snapshot date, for example 'Source: Illinois Department of Financial and Professional Regulation · Snapshot 2026-06-15'. Each board sets its own open-records reuse terms, which vary by state and are not the uniform federal public-domain footing.
