Answer questions about daily impact, your housing situation and the animal's role. Costs nothing, requires no card, and tells you whether an ESA housing letter is even the right pathway before you spend anything.
An emotional support animal letter only carries weight when it comes from a licensed professional after a real evaluation. Here's exactly how the process works — and how to avoid the "instant registry" traps.
Start free screeningFirst, the basics
An ESA (emotional support animal) letter is a signed document from a licensed mental-health professional stating that your animal helps manage symptoms of a diagnosed condition. It is used to request a reasonable accommodation in housing under the federal Fair Housing Act. It is not a "registration," a vest, or an ID card — those products are sold widely online but carry no legal weight on their own. The letter, signed by a clinician, is the document that matters.
With a valid letter, your support animal is treated as a reasonable accommodation — so pet deposits, monthly pet rent, and breed or weight limits generally do not apply.
Step by step
Answer a short questionnaire about your symptoms, your living situation, and your animal. There's no charge and no obligation.
If a clinical review looks appropriate, your information goes to a professional licensed in your state.
The clinician evaluates whether an emotional support animal is part of your care. You only pay if you qualify and choose to proceed.
Approved letters are delivered digitally, usually within 24–48 hours, with details a housing provider can confirm.
Eligibility
A licensed provider makes the determination, but people commonly seek an ESA evaluation while managing conditions such as:
For general information only — this is not a diagnosis or a guarantee of qualification.

Watch out
There is no official ESA registry. Sites selling instant "registration," IDs, or vests without an evaluation are selling something you don't need.
A letter that isn't signed by a professional licensed in your state can be rejected by housing providers.
Many providers expect a current letter. Plan to renew so there are no gaps in your documentation.
Cost & timeline
The initial screening is free. If you qualify and choose to move forward, pricing is shown up front and most approved letters are delivered within 24–48 hours. Compare options on our pricing page.

Qualifying is not about naming a condition. A clinician is asking whether a mental or emotional condition substantially limits a major life activity, and whether the animal helps alleviate an effect of that limitation. These are simply the reasons people most often start an evaluation.
Educational list only. It is not a diagnosis, and appearing here does not guarantee a clinician will approve documentation.
The route
Answer questions about daily impact, your housing situation and the animal's role. Costs nothing, requires no card, and tells you whether an ESA housing letter is even the right pathway before you spend anything.
A fuller picture: symptom history, how the limitation shows up at home, and what changes when the animal is present. This is what the clinician actually reads, so specifics beat generalities every time.
A professional licensed where you live evaluates the case and may approve, decline, or ask follow-up questions. This is the step registry sites skip — and the reason their documents get rejected.
Approved letters arrive in your account with credentials, a current date, a signature and a verification route. Send it to your landlord with a short written accommodation request and keep the dated copy.
Avoid the money pit
A letter your landlord rejects costs more than it saved. If a site does any of these, walk away before paying.
