California, Colorado and Virginia protect dietitian titles but issue no license or certification, and Arizona has no dietitian licensure law. No state credential is available there. Medicare accepts CDR registration in those states, but residents cannot use the Dietitian Compact and need licenses in each client state that requires one.
Most states regulate dietitians through a license or a certification. Four do not issue either. California, Colorado and Virginia protect certain titles in statute without any state credential, and Arizona has no dietitian licensure law. Two more states, Michigan and New Jersey, have statutes but are not granting licenses while their regulations are pending; they have their own post.
No state credential sounds simple. It cuts both ways: easier for out-of-state dietitians serving clients there, harder for dietitians who live there and serve clients elsewhere.
What does title protection mean in California, Colorado and Virginia?
The Academy of Nutrition and Dietetics says "California, Colorado and Virginia laws restrict the usage of specified titles to use by defined credentialed practitioners, but do not require licensure or certification by the state." There is no board to apply to and nothing to renew. The law regulates what you call yourself, not whether you may practice.
Virginia
Virginia's statute bars anyone from holding themselves out or advertising as a "dietitian" or "nutritionist" unless they meet one of six listed qualifications. They include active CDR registration; a baccalaureate or higher degree in a nutrition field plus a CDR-approved supervised clinical program; an active Certified Nutrition Specialist credential; a Diplomate of the American Clinical Board of Nutrition; and "a current license or certificate as a dietitian or nutritionist issued by another state." The restriction covers those words alone or combined with "licensed," "certified" or "registered" (Va. Code § 54.1-2731).
California
California's Business and Professions Code says its medical practice chapter "shall not be construed to prohibit any person from providing nutritional advice or giving advice concerning proper nutrition," while making clear that this confers no authority to diagnose or treat disease (Bus. & Prof. Code § 2068). The same section requires anyone in commercial practice providing nutritional advice to post a prescribed notice in their place of business. A separate chapter covers registered dietitians: Section 2586 lets a registered dietitian or other qualified nutritional professional, upon referral by a health care provider authorized to prescribe dietary treatments, provide nutritional and dietary counseling, assessments and therapeutic diets, with the referral for medical nutrition therapy accompanied by a written prescription, as quoted in the Academy's California summary.
Colorado
Colorado is grouped with California and Virginia in the Academy's summary: titles restricted, no state license or certification. The Academy's March 2026 telehealth chart answers "No" for Colorado on whether the state provides for licensure or certification.
Why is Arizona different?
Arizona has no dietitian licensure law. The Academy's telehealth chart says "No current licensure law for dietitians; no board or agency to register with." Arizona does have a general interstate telehealth registration statute (Ariz. Rev. Stat. § 36-3606), but with no dietitian board there is nothing for a dietitian to register with.
Can an out-of-state dietitian see clients in these states?
As far as state dietitian licensing goes, no state credential exists to get. CDR's guidance on serving clients in other states carves out exactly this case: the duty to follow the client state's licensure laws applies "unless exemptions apply or a state does not regulate the dietetics profession through licensure or certification." Watch the titles in California, Colorado and Virginia, and keep the line in California between nutrition advice and the practice of medicine. Your employer, your malpractice carrier and your payers can still set their own requirements.
How does Medicare treat these states?
Medicare requires a dietitian providing medical nutrition therapy to be licensed or certified by the state where services are performed, but "in a State that does not provide for licensure or certification," recognition as a registered dietitian by CDR satisfies that requirement (42 CFR 410.134(c)). Keep your CDR registration current: CDR says the credential "lapses on October 1" if the annual maintenance fee is not received. See Medicare MNT and licensure.
What if you live in one of these states and see clients elsewhere?
This is where no license becomes a disadvantage.
- No home license. Every other state's requirements apply to you in full. A Florida telehealth registration, for example, requires an active license from another state, so a dietitian whose only credential is CDR registration has to get a license somewhere first.
- No compact. The Dietitian Licensure Compact requires a member state to "License and regulate the Practice of Dietetics" (Model Compact § 3.A), and the Commission's FAQ names California, Colorado, Virginia and Arizona among states that "would not be able to participate." CDR's compact page is blunt: "If you live in a state that doesn't have licensure (eg, CA, AZ)… you cannot use the Compact." No state issues privileges yet in any case.
- Endorsement may still work. CDR says the RD's requirements qualify you for licensure or certification in every state that regulates dietetics, and it calls endorsement of the RD credential "usually the easiest route if a state provides for it." Where a state's endorsement route depends on holding another state's license, you may need its RD or examination route instead.
A California telehealth dietitian with clients in Florida, Ohio and Georgia therefore needs three credentials, and will keep needing them after the compact opens. That is the profile our multi-state packages were built for.
Could these states start licensing?
Any could, by statute. Michigan and New Jersey show the path is slow: both enacted laws, and neither has regulations in effect that allow licenses to issue. If one of these states adopts licensure, its residents could later become compact-eligible if it also joins. We update our state license index when that changes.
Can we help dietitians in these states?
Yes. A Readiness Review ($149) maps which of your client states need a credential and which route fits a dietitian with no home license. We prepare each application and track it; you review, sign, pay the board and submit. Multi-State Telehealth Packages are $1,499 for three states and $2,299 for five. See California, Colorado, Virginia and Arizona on the index.
Common questions
- Does California license dietitians?
- No. California restricts certain titles but issues no dietitian license or certification. Its law allows anyone to give nutrition advice without authorizing the practice of medicine.
- Does Arizona license dietitians?
- No. The Academy of Nutrition and Dietetics says Arizona has no current licensure law for dietitians and no board or agency to register with.
- Can a California dietitian use the Dietitian Compact?
- No. A compact home state must license and regulate dietetics, and California does not. CDR says residents of states without licensure cannot use the compact.
- Who may call themselves a dietitian in Virginia?
- Someone meeting one of the qualifications in Va. Code 54.1-2731, which include active CDR registration, a CNS credential, or a dietitian or nutritionist license or certificate from another state.
