What Dietetic Technician, Registered covers
A Dietetic Technician, Registered (DTR)/Nutrition and Dietetics Technician, Registered (NDTR) is an individual holding a nationally protected title issued by the Commission on Dietetic Registration (CDR) to qualified individuals who obtain an associate's degree or higher and successfully complete a sliding set of academic, examination, and practice requirements accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND) or established by CDR, the nature of which are dependent upon the level of academic degree obtained. The scope of practice of the NDTR focuses on food, nutrition, and dietetics practice, as well as related services. NDTRs work under the supervision of a Registered Dietitian Nutritionist (RDN) when in direct patient/client nutrition care, and may work independently in providing general nutrition education to healthy populations. Patient/client populations include individuals receiving individualized care who have medical conditions or diseases, as well as at-risk individuals receiving personalized nutrition guidance as part of preventive health care.

Full NPPES record
An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check
How the check works, step by step
Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.
| Digit | 8 | 0 | 8 | 4 | 0 | 1 | 1 | 4 | 4 | 8 | 4 | 1 | 7 | 5 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 1 | 8 | 4 | 7 | 4 | 2 | 7 | 1 |
Sum = 60 · next multiple of 10 = 60 · check digit = 0 · actual last digit = 0
A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
