CDR Registration Is Not a State License

Many dietitians use "my RD" and "my license" as if they were the same thing. They are not, and the difference has real consequences when you practice across state lines. The Commission on Dietetic Registration (CDR) says it plainly in its February 2026 credentialing tip: CDR certification and state licensure "are unique processes that have different eligibility requirements and purposes."

What is CDR registration?

CDR is the credentialing body connected with the Academy of Nutrition and Dietetics. It awards the Registered Dietitian (RD) and Registered Dietitian Nutritionist (RDN) credentials, and the technician credentials (DTR and NDTR), to people who complete the academic and supervised practice requirements and pass the registration exam. CDR's use-and-misuse page says these designations "are the exclusive property of the Academy of Nutrition and Dietetics."

Keeping it requires an annual registration maintenance fee to CDR and, for an RD, at least 75 continuing professional education units every five years, including one in ethics or health equity. CDR describes the RD as "nationally recognized."

What is a state license?

A state license, certification or title authorization comes from a state agency under a state statute. CDR's definition: "Most states require dietetics practitioners (RDs or others) to hold a state license or certification to legally practice or utilize a protected title within that state. Requirements vary from state to state." A state credential can be revoked or restricted by that state's board, carries that state's continuing education and renewal rules, and authorizes you only in that state.

How do the two connect?

Closely. CDR says "the requirements to obtain the RD credential qualify one for licensure or certification in all states that regulate the practice of dietetics and nutrition." Many state laws use your RD as a shortcut:

• Ohio waives its education, experience and exam requirements for a CDR-registered dietitian (Ohio Rev. Code 4759.06(B)).
• Florida waives its exam for a registered dietitian or RDN who meets its other qualifications (Fla. Stat. § 468.509(4)).
• Texas accepts the CDR registration exam as its licensing exam, alongside its own jurisprudence exam.

CDR calls endorsement of the RD credential "usually the easiest route if a state provides for it." But a shortcut to a license is still an application to a state, with a fee, a background check where required, and a board decision. See license by endorsement.

Does your RD let you practice in any state?

No. The RD is a national certification; practice authority comes from states. CDR's own guidance: practitioners delivering in-person or telehealth services to clients in other states "must obtain, maintain, and comply with all applicable licensure and telehealth-specific laws and regulations of the states in which the patients/clients are physically located at the time of service," unless an exemption applies or the state does not regulate dietetics through licensure or certification.

Where the state issues nothing (California, Colorado, Virginia, Arizona, and Michigan and New Jersey while their regulations are pending), your RD is what employers and payers look at, and Medicare accepts CDR registration in place of a state license there (42 CFR 410.134(c)). Everywhere else, the state credential is what authorizes you.

Where do the two get confused in practice?

• Telehealth across states. "I'm an RDN, so I can see clients anywhere" is the most common and most costly assumption. In a state like Florida that restricts practice to licensees, it is unlicensed practice.
• Titles. Ohio lets a CDR-registered dietitian use "registered dietitian" and "R.D." only if they are not violating Ohio's license requirement (Ohio Rev. Code 4759.02(C)). Texas requires its license to use "licensed dietitian" or "LD." New York requires certification for "Certified Dietitian" and "Certified Nutritionist."
• Renewal calendars. CDR's maintenance fee is due August 31 each year, and the credential "lapses on October 1" if payment is not received. State licenses run on their own cycles: Georgia's expire March 31 of even-numbered years, Illinois's October 31 of odd-numbered years.
• Continuing education. CDR itself warns that its requirements "may differ from requirements for state licensure." Pennsylvania, for example, requires 2 of its 30 credits in child abuse recognition and reporting.
• Payers. Some insurers look for the RD; Medicare and, per CDR, some Medicaid programs and private insurers look for state licensure or certification.

Does a lapsed RD affect your state licenses?

That depends on the state. Whether a state requires current CDR registration to renew is something to confirm in each state's renewal rules, so read them for every state where you are licensed. For CDR, the consequences are spelled out: after a lapse for nonpayment, you regain registered status by passing the exam again or by paying the reinstatement and past maintenance fees, as long as recertification requirements are current. A lapse also matters for the Dietitian Licensure Compact once it opens, since current RD registration is the main route to eligibility.

How should you track both?

Keep one list: CDR registration number, maintenance fee date, Professional Development Portfolio cycle end date, and then each state credential with its number, type, expiration date, continuing education rule and fee. Our Annual Renewal and CE Compliance service ($299 per license, per year) keeps that list for you and flags each deadline. When you need a new state license, we prepare the package and track it while you review, sign, pay the board and submit. See pricing or check each state on the license index.
