Here is what to know about your provider before you book an evaluation.

Key Takeaways

Licensed providers qualify: A licensed mental health professional or a qualified healthcare provider can write a valid letter.

No letter required for public access: The ADA only allows two questions. Documentation is not required.

State license matters more than location: A telehealth provider must be licensed in your state.

Registries don't count: Online certification sites cannot issue a valid letter.

One evaluation is often enough: An ongoing relationship with your provider is not always required.

Which Professionals Can Legally Write a PSD Letter?

A licensed mental health professional or a qualified healthcare provider with an active state license can write a valid PSD letter. The provider does not need one specific job title. They do need an active license and direct knowledge of your mental health condition.

Psychiatrists

A psychiatrist can write a valid PSD letter. A psychiatrist is a medical doctor who specializes in mental health. They can diagnose your condition and confirm that it qualifies under the ADA. Many people already see a psychiatrist for medication management. Adding this letter to a normal visit is simple.

Psychologists

A psychologist can also write a valid PSD letter. A psychologist holds a doctoral degree in clinical psychology. They diagnose mental health conditions through therapy and clinical evaluation. Their letter carries the same weight as a psychiatrist's for PSD purposes.

Licensed Clinical Social Workers (LCSWs)

A licensed clinical social worker can write a valid PSD letter. An LCSW holds a state license in clinical social work. They provide ongoing mental health counseling and can diagnose qualifying conditions. Many people already work with an LCSW for regular therapy.

Licensed Professional Counselors (LPCs) and Licensed Marriage and Family Therapists (LMFTs)

An LPC or an LMFT can write a valid PSD letter. Both hold a state license to provide mental health counseling. LPCs typically focus on individual therapy. LMFTs focus on relationship and family therapy. Both can evaluate an individual's condition for a PSD letter.

Psychiatric Mental Health Nurse Practitioners (PMHNPs)

A psychiatric mental health nurse practitioner can write a valid PSD letter. A PMHNP is an advanced practice nurse who specializes in psychiatric care. They can diagnose conditions and manage medication. Their exact scope of practice varies slightly by state.

Primary Care Physicians and General Practitioners

A primary care physician can also write a valid PSD letter. This includes general practitioners who manage your overall care. A PCP may refer you to a specialist first if your condition needs a more detailed evaluation. 

A PSD letter written by a licensed professional  gives you public access and travel rights for your service dog. Explore our detailed guide on what a psychiatric service dog letter is to learn more. 

Does Your PSD Letter Need to Come From an In-State Provider?

Yes. Your provider must hold an active license in the state where you live. This applies even when the evaluation happens over telehealth.

• A therapist licensed only in another state generally cannot write your letter.
• Many providers now offer remote evaluations through an online PSD evaluation instead of an in-person visit.
• Some psychologists can practice across state lines under PSYPACT, an interstate compact for licensed psychologists.
• PSYPACT does not cover every profession or every state. Check your provider's compact status before booking a telehealth session.

Who Cannot Write a PSD Letter?

An unlicensed professional cannot write a valid PSD letter. Neither can an online registry with no real clinician behind it. A valid letter must come from someone who holds an active state license and has evaluated your condition directly.

Sources that cannot write a valid letter include:

• Online registries that have no licensed clinician reviewing your case
• You yourself, since a self-signed form involves no clinician evaluation
• Sellers of ID cards or vests, who never evaluate your condition at all

Every RealESALetter.com PSD letter names the clinician's active license number and issuing state so the provider's qualification can be verified directly.

A valid PSD letter also has to meet specific requirements before it will be accepted. Our guide on psychiatric service dog letter requirements covers the full list in detail.

Do You Need an Ongoing Relationship With Your Provider?

No. Most people can get a valid PSD letter after a single evaluation. An ongoing treatment relationship is not always legally required.

Why Some PSD Providers Carry More Weight Than Others

A letter signed by a mental health specialist often faces less pushback than one signed by a general practitioner. 

Landlords and airlines are more familiar with psychiatric and psychological evaluations. 

Conclusion

Not just anyone can write a PSD letter. It takes a licensed mental health professional or a qualified healthcare provider with an active state license. Skipping this step with a registry certificate can leave you without real protection.
