US Dietitian & Nutritionist Licenses

15,000+ dietitian and nutritionist licenses from official state registries — licensed dietitians and nutritionists from Illinois and Delaware. Every state that publishes its full license roster through an official data feed gets added as we find it - no request needed.

Who this is for

• Wellness, supplement & food brands — licensed dietitians are the credible-recommender channel; filter by city to build outreach territories.
• Hospitals, senior care & telehealth nutrition platforms — the new licenses filter surfaces newly licensed RDs the week they're licensed.
• Recruiters & staffing firms — build hiring lists from the official roster instead of stale directories.
• Credentialing teams — bulk license verification with disciplinary flags against the official state record.

What you get

One normalized record per license: name, license number, category, city, status, issue and expiration dates, computed expires_in_days, is_expiring_soon, is_new_license, and ever_disciplined flags. Export to Excel, CSV, or JSON, or pull on a schedule via API.

One schema across every state

Every licence roster in this catalogue delivers the same columns, in the same order, meaning the same thing — whichever state or profession the records came from. Stack this dataset on top of any other KempData roster and the columns line up.

That takes real work. Illinois writes a lapsed licensee as NOT RENEWED in block capitals; Delaware writes the identical situation as Delinquent. Both arrive here as status: "lapsed". Names arrive SHOUTING and glued together; they leave as full_name, first_name, middle_name, last_name in proper case. Dates are MM/DD/YYYY, with an _iso twin for spreadsheets and imports.

The state's own word is never thrown away. Every translated value ships beside a *_raw twin — status_raw, credential_raw, name_raw — holding the source's exact string, so you can always check our work or apply your own rules. status_basis tells you whether the standing is the state's published fact or computed from the expiration date.

lapsed is worth knowing about. It is the recall pool: people who held the licence, let it run out, and can renew. When you need experienced people in a hurry, that is the list to call.
