How Do You Spot a Legitimate PSD Letter Service?
A legitimate PSD letter service uses a live call with a clinician licensed in your state. Use this table to test any provider before you pay.
Check | Legitimate Service | Red Flag |
Evaluation | Live call with a clinician | Approval from a quiz alone |
Clinician | Name and license you can look up on your state board | No name or license before payment |
What it sells | Letters only | Registrations, ID cards or vests sold as proof |
Training | Says training is your job | Claims the clinician certifies your dog |
Air travel | Points you to the DOT Service Animal Air Transportation Form | Sells a separate "PSD travel letter" |
Housing | Explains the 2026 HUD change | Guarantees landlord approval |
The ADA defines a service animal as a dog trained to perform tasks for a person with a disability. A clinician documents your disability-related need. Training your dog is your job. Online registrations carry no rights under the ADA.
Every RealESALetter.com PSD letter lists the clinician's state license number, issue date and contact details so a housing provider can verify it.
Housing rules also changed this year. Before May 2026 HUD guidance treated trained and untrained assistance animals alike. Since May 22, 2026 HUD gives priority to housing requests for trained animals. See how a PSD letter and housing rights fit together now.
Which PSD Letter Service Fits Your Situation?
Your state and your timeline decide the right PSD letter service. Your dog's training matters too.
- You need it fast: Most services issue the letter within 24 hours of the call. RealESALetter.com assigns a clinician the same day and issues the PSD letter within 24 hours of the consultation. Arkansas, California, Iowa, Louisiana and Montana take longer.
- You live in AR, CA, IA, LA or MT: California's AB 468 sets a 30-day rule for emotional support dog letters. The other four states have similar ESA rules. Some services apply the same wait to PSD letters.
- You already see a therapist: Your own licensed clinician can write the letter. An online service helps if they decline.
- Your dog is not task-trained: A PSD letter is the wrong document. An ESA letter covers housing instead.
Conclusion
Pick a PSD letter service with a licensed clinician and a live call. Look for clear refund terms in writing. Skip any site that sells registries as proof or promises to certify your dog. See if you qualify for a PSD letter with a free check before you pay.
Frequently Asked Questions
How do I check a PSD letter service's clinician before I pay?
Look up the clinician on your state licensing board website. Search by name or license number. Confirm the license is active and covers mental health. A legitimate service shows the clinician's name before you pay.
Should a PSD letter service approve everyone?
No. A real clinician can decline you. Some people do not meet the criteria for a PSD letter. A service that promises approval to everyone skips a real evaluation.
Can I trust reviews on a PSD letter service’s own website?
Use them as one signal only. The seller chooses which reviews to show. Check independent review sites too. A license lookup tells you more than any review.
How should a PSD letter service protect my health information?
It should keep your records private and share them only with your consent. Ask how it stores your data. Read the privacy policy before you pay.
Should a PSD letter service charge me on a subscription?
Not for a single letter. A one-time letter should have a one-time price. Check for automatic renewal charges before you pay. Cancel terms should be in writing.
