Administrator Registered Nurse: how many are there, and how many are in private practice?

National totals

Reading the sole-proprietor share

For this specialty, 839 of the 2,374 active records, or 35.3%, are flagged as sole proprietors in NPPES. The field is self-reported and is an imperfect proxy for private practice, because it does not by itself establish ownership, employment status, or whether a provider works independently.

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.
• The count is based on active NPI records with this taxonomy as the primary classification, not a separately verified census of people or practices.
• NUCC has not published an official definition for Administrator Registered Nurse, so the taxonomy label may not describe each provider’s role in detail.
• Providers are counted once, by their primary taxonomy code only.
