How does dietitian licensure differ by US state, and what does it mean for marketing and telehealth?
Dietitian licensure differs sharply by state: most states license dietitians, some only certify or protect titles, and a few, such as California and Arizona, have no license at all. For marketing, the rule is simple. Use only the titles you hold in the reader's state, and offer telehealth medical nutrition therapy only where you are licensed. The interstate compact is expected to start issuing privileges in 2027.
- Four models exist: licensure, certification, title protection, and no statute. Match your marketing to the strictest state you serve.
- Telehealth follows the client: licensure laws generally apply where the client is during the session, with narrow exceptions.
- The Dietitian Licensure Compact is enacted but not yet issuing privileges; CDR expects the first in 2027.
- Titles must match credentials in every state across your website, Google profile, ads and social bios.
- Every practice welcome — retainers from $499/mo, Goals-Driven engagements, Performance-Linked Payout Models available.

“They were able to get all my ideas and work with me over a period of three to four months and create this amazing website. It's super customized, very modern, and it incorporates all the elements that I had wanted — the patient portal, nice pictures, a very interactive website, patient reviews. I would highly recommend their company to anyone who wants to make an excellent website.”
Do all US states license dietitians?
No. States regulate dietitians in four different ways: full licensure, certification, title protection only, or no statute at all. A licensure state can make it illegal to practice without a license. A title-protection state only stops unqualified people from using certain titles. Your marketing has to match the strictest rule in every state where your clients live.
The Commission on Dietetic Registration (CDR) credentials registered dietitians and registered dietitian nutritionists (RD/RDN) nationally. That credential is not a state license. A national RDN still needs whatever each state requires, and CDR itself notes that dietitians in states without licensure, such as California and Arizona, cannot use the new interstate compact (see the Commission on Dietetic Registration (CDR) compact page).
The four models, and what each means for marketing
| Model | What the law controls | What it means for your marketing |
|---|---|---|
| Licensure (practice act) | Who may provide dietetics or medical nutrition therapy (MNT), and who may use the titles | Only market MNT to residents of the state if a licensed clinician will serve them. Show the license by state. |
| Certification | Who may use a certified title; practice is often open | Use the certified title only if you hold it. Describe services accurately without implying certification. |
| Title protection | Use of specific titles such as "dietitian" or "licensed dietitian" | Titles in ads, profiles and bios must match the credential held. |
| No statute | Nothing specific to dietetics; general consumer-protection and deceptive-advertising law still applies | Claims must still be truthful. Payers and employers may still require a credential. |
The labels are a starting point. Two "licensure" states can differ a lot in exemptions, in what counts as MNT and in how they treat out-of-state telehealth. Our dietitian licensure glossary entry explains the terms.
What is the dietitian licensure status in each state?
Most states license dietitians, a smaller group certifies or protects titles only, and a few have no dietetics statute. The table below uses CDR's state licensure summary as the base. We checked eight high-population states and several compact states against official sources in October 2026. Rows marked "verify" are not yet confirmed by us.
CDR's summary is undated and some rows are out of date. New Jersey, for example, appears there as "no statute", yet its licensing act (P.L.2019, c.331) was approved in January 2020, and Georgia rewrote its law in 2026. Treat every "verify" row as a prompt to check the state board's own website before you publish anything state-specific.

How do the rules compare in eight high-population states?
Among the eight states we verified, five license dietitians (Florida, Georgia, Illinois, Ohio, Pennsylvania), though what needs a license differs. Texas licenses only the "licensed dietitian" title, New York certifies titles, and California protects titles without a license. Two of the eight, Ohio and Georgia, have enacted the interstate compact. Each state has a detailed guide.
| State | Model | Who regulates | Key verified point | Compact |
|---|---|---|---|---|
| California | Title protection | No dietetics board | Cal. Bus. & Prof. Code § 2585 sets who may call themselves a registered dietitian | No |
| Texas | License protects the title | Texas Department of Licensing and Regulation (TDLR) | A license is needed to use "Licensed Dietitian" or "LD"; TDLR says one is not needed to use "dietitian" or "nutritionist" alone | No |
| Florida | Licensure | Dietetics and Nutrition Practice Council under the Board of Medicine | Fla. Stat. § 468.504: no paid dietetics, nutrition practice or nutrition counseling without a license | No |
| New York | Certification | State Education Department | N.Y. Education Law § 8002 protects "certified dietitian" and "certified nutritionist" | No |
| Illinois | Licensure | Department of Financial and Professional Regulation | 225 ILCS 30/15: a license is required to provide MNT or hold out as a licensed dietitian nutritionist | No |
| Pennsylvania | Licensure (LDN) | State Board of Nursing | The Pennsylvania State Board of Nursing LDN snapshot describes the LDN as a license to practice dietetics-nutrition | No |
| Ohio | Licensure | State Medical Board of Ohio | Ohio Rev. Code § 4759.02: no practice of dietetics or use of "dietitian" without a license, with listed exceptions | Yes |
| Georgia | Licensure (dietitian and nutritionist) | Georgia Board of Examiners of Licensed Dietitians and Licensed Nutritionists | Georgia HB 185 (as passed): a license is needed for MNT; general wellness advice is exempt | Yes |

Can a dietitian see clients in another state by telehealth?
Usually only if the dietitian meets the rules of the state where the client is located at the time of the session. Licensure states generally apply their law to care delivered to residents in the state, whatever the clinician's home state. Exemptions for out-of-state clinicians exist but are narrow and differ by state.
Georgia's 2026 law is a good example of how narrow they can be. Georgia HB 185 (as passed) exempts an out-of-state licensed or certified dietitian only in limited cases: a client temporarily in Georgia, short-term follow-up for continuity of care, or consultation with a Georgia-licensed practitioner who has the patient relationship. It is not a general permission to market to Georgia residents.
What this means for a virtual practice
- List the states you serve on the website, booking page and intake form, and match it to your licenses.
- Ask for the client's location at booking and route out-of-state enquiries to a clinician licensed there, or decline politely.
- Separate MNT from general wellness. Several states, Georgia included, exempt non-medical wellness advice. Do not let wellness marketing drift into disease-management promises.
- Medicare adds its own layer. Medicare Part B covers MNT by a registered dietitian or nutrition professional for diabetes and kidney disease with a referral (42 CFR §§ 410.130–410.134). Telehealth billing rules have changed several times; check current CMS guidance.
Our explainer on telehealth across state lines covers the general principle. For insurance-funded work, see marketing insurance-covered nutrition counseling.
What is the Dietitian Licensure Compact, and when will it help?
The Dietitian Licensure Compact is an agreement among member states that will let a qualifying dietitian practice in other member states through a "compact privilege" instead of a full second license. It is enacted but not yet issuing privileges. CDR says the first compact privileges are expected sometime in 2027.
The compact became active once seven states enacted it, which formed the Compact Commission. According to CDR, a dietitian may be eligible if they are a Registered Dietitian, hold an active, unencumbered license in their home state, and that home state is a member. The model text, as enacted in Georgia and Washington, also sets an alternative route for licensees who are not RDs but meet its education, supervised-practice and exam requirements.
Where it stands, as of October 2026
| Question | Answer | Source |
|---|---|---|
| Is the compact in force? | Yes, activated after seven states enacted it | Commission on Dietetic Registration (CDR) compact page |
| Are privileges being issued? | Not yet; first privileges expected in 2027 | Commission on Dietetic Registration (CDR) compact page |
| Who can use it? | RDs licensed in a member home state; not RDs based in non-licensure states such as California and Arizona | Commission on Dietetic Registration (CDR) compact page |
| How many members? | 19 states on the CSG tracker when we checked in October 2026. We confirmed Ohio, Georgia, Iowa, Kentucky, Missouri and Washington in statute; some take effect later (Washington on July 1, 2028) | CSG compact page, Ohio Rev. Code § 4759.30, Iowa Code chapter 147K, RSMo § 324.1800 |
| Does it change marketing now? | Not until privileges are issued; keep marketing within states where you hold a license today | Our reading; confirm with counsel |
Plan for it, but do not market multi-state availability on the strength of the compact until your privilege in each state is granted.
How should licensure shape the credentials and claims in your marketing?
Every title in your marketing must be one you hold in the state where the reader is. That covers website bios, Google Business Profile, ad copy, social profiles, directory listings and email signatures. In licensure states, describing services as medical nutrition therapy for a disease implies licensed practice.
Credential display rules of thumb
- Show the national credential (RD or RDN) and the state credential separately, for example "RDN, LD (Texas)" or "LDN (Illinois)".
- For multi-state clinicians, list each state license on the bio page, with license numbers if the board expects them.
- Never use "licensed" in a state where the person is not licensed. In Georgia the 2026 law also protects "nutritionist" unless licensed or exempt.
- Health coaches and other non-licensed staff need titles that do not imply licensure, and their service pages must stay within wellness.
Health claims
Licensure does not replace advertising law. The FTC still expects health claims to be truthful and backed by competent and reliable scientific evidence, and its 2024 rule bans fake reviews and testimonials. Our guide on advertising rules for dietitian health claims covers this in detail.
How should a multi-state telehealth dietitian practice set up its marketing?
Build marketing around the list of states where you can legally serve clients. Each licensed state gets a page, ads target only those states, intake checks location, and your Google Business Profile reflects how you actually serve clients. This keeps spend away from people you cannot see.
- State service pages. One page per licensed state, naming the clinicians licensed there and the services offered. Add each new state as licenses are granted.
- Geo-targeted ads. Set Google Ads and Meta location targeting to licensed states only. Exclude the rest.
- Intake gating. Ask "Which state will you be in during your sessions?" as the first booking question.
- Google Business Profile. Google expects in-person contact with customers. A virtual-only practice may not qualify; see Google Business Profile for virtual dietitian practices.
- Insurance pages. Payer networks are state-specific. List plans by state rather than one national list.
- Review the list each quarter. Licenses lapse, laws change, and the compact is expected to add options from 2027.
A worked example
Take an RDN based in Ohio who also holds a Pennsylvania license and wants Florida clients. Ohio and Pennsylvania pages can go live now, with ads targeted to those two states. Florida stays off the website, the ad targeting and the booking form until a Florida license is issued, because Florida restricts paid nutrition practice and counseling to licensees. Once the compact issues privileges, Ohio's membership may open other member states, but Florida and Pennsylvania were not members when we checked, so separate licenses would still be needed there.
This is how we scope telehealth work for dietitians on our dietitian marketing agency services page. We sign a Business Associate Agreement (BAA) with every US client and keep tracking on booking and intake flows HIPAA-safe.
How do you keep state-by-state claims accurate over time?
Treat licensure facts like prices: date them, source them, and review them on a schedule. Keep a simple register of each state you serve, the rule, the official source link and the date checked. Update website copy and ads when anything changes, and run material changes past counsel.
- Sources to check: the state board or licensing agency, the state code on the legislature's site, and the compact commission for privileges.
- Triggers for a review: a new state license, a legislative session ending, a board rule change, or a new service line such as GLP-1 nutrition support.
- Who owns it: one named person in the practice, with your agency flagging any copy that mentions a state, a title or a coverage claim.

Common questions
Which states do not license dietitians?
California, Arizona, Colorado, Michigan and Virginia do not license or certify dietitians, according to the Dietitian Licensure Compact's own site. California and Virginia protect certain titles instead, and Colorado relies on deceptive-advertising law. Status changes, so confirm with each state board before relying on any list, and treat this as general information, not legal advice.
Do I need a license in every state where my telehealth clients live?
Generally yes, if the client's state licenses dietitians and you provide medical nutrition therapy. Licensure laws usually apply where the client is located during the session. Some states allow narrow exceptions, such as temporary travel or short-term follow-up. Check each state's rules and confirm with counsel before accepting clients there.
Is the Dietitian Licensure Compact active yet?
Yes, in the sense that it is in force: at least seven states enacted it, which created the Compact Commission. As of October 2026 it was not yet issuing compact privileges, and the Commission on Dietetic Registration says the first are expected sometime in 2027. Until then, dietitians need a license in each licensure state they serve.
Can a registered dietitian practice anywhere with just the CDR credential?
No. The RD or RDN credential from the Commission on Dietetic Registration is national, but it is not a state license. In licensure states, a dietitian still needs the state license to provide medical nutrition therapy or to use protected titles such as "licensed dietitian". In title-protection states the credential mainly governs which titles can be used.
Can a virtual dietitian practice have a Google Business Profile?
Often not. Google expects businesses with a profile to make in-person contact with customers during stated hours, so a fully virtual practice may not qualify. A practice with a real office where clients can visit can list that location. Virtual practices usually rely on state service pages, search ads and referrals instead.
How often should a dietitian practice review state licensure information on its website?
At least every quarter, and whenever you add a state, a clinician or a service line. Legislatures change dietetics laws, as Georgia did in 2026, and the interstate compact is expected to add new options from 2027. Keep a dated register of the rule and source for each state you serve, and confirm material changes with counsel.
A note on this guide: it explains marketing practice, not legal advice. Rules on privacy, advertising and insurance change and vary by state, so confirm anything compliance-related with your own counsel.
