How we verify

Hearing Clinic Finder is compiled from public records, not from who paid to be listed.

Sources

• NPPES NPI Registry (CMS) — The federal registry of National Provider Identifiers, published monthly by the Centers for Medicare & Medicaid Services. We use the September 2026 bulk file.
• NUCC Health Care Provider Taxonomy — The code set that defines each registered specialty (for example 231H00000X, Audiologist).

We load every active NPI in the NPPES data (the monthly bulk file plus CMS's weekly updates) whose primary taxonomy is Audiologist (231H00000X), Audiologist-Hearing Aid Fitter (237600000X) or Hearing Aid Equipment (332S00000X). Deactivated NPIs are excluded.

The registered specialty, credentials and license number are what each provider entered when registering. NPPES does not verify them, so we label them as registered or listed and link every profile to the official registry record. Always confirm a license with your state board.

We drop individual clinicians whose NPI record has not been updated since before 2013, because providers must update NPPES within 30 days of a change and a record untouched for over a decade usually belongs to someone who has retired or moved. Organizations are kept regardless.

Hearing Aid Equipment (332S00000X) is a supplier category for businesses that sell hearing aids; it is not a clinical license. Those listings say so.

Order within a city: clinics and practices first, then individual clinicians; within each, records updated most recently first, then alphabetical. Featured listings appear in a separate, labelled box and never change that order.

What a badge means

Registry-checked: the provider's National Provider Identifier (NPI) is active in the September 2026 NPPES file published by CMS. Each listing shows the registered specialty and any license number exactly as the provider entered them. We only publish positive matches. A listing without a badge is not an accusation — most gaps are name variations between registries.

Freshness

Data was last refreshed on 2026-10-21. CMS publishes the full NPPES file every month and weekly update files in between; we apply both every week, so listings are at most about a week behind, and every page shows the date of the data.
