Hearing Aid Equipment: how many are there, and how many are in private practice?

National totals

What this specialty covers

The manufacture and/or sale of electronic hearing aids, their component parts, and related products and services on a national basis.

Reading the sole-proprietor share

For this specialty, 60 records, or 1.7%, are flagged as sole proprietors in NPPES. Because this field is self-reported and may not capture ownership, staffing, contracting, or organizational relationships, it is an imperfect proxy for private practice and should not be read as a count of independently owned hearing-aid businesses.

By state

New NPI registrations by year

Counts reflect the year each NPI was first issued, among records still active today. The final year is partial: this data covers through 2026-01-11.

Data notes

• The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
• A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
• - An active NPI record is not necessarily a unique business, location, individual provider, or operating supplier.
• - Primary taxonomy, active status, and enumeration dates depend on NPPES records and submitted updates, so classifications and timing can change.
• Providers are counted once, by their primary taxonomy code only.
