ESA Letter Legitimacy Checker: 8 Elements a Real Letter Has
The ESA document market has two ends: letters written by licensed professionals after a real evaluation, and PDFs sold by websites after a two-minute form. Housing providers know the difference, and they're allowed to check. This checker runs a letter through the eight elements a provider is entitled to expect under the Fair Housing Act framework, answer for the document in front of you, and see where it stands before someone else judges it for you. Anything you can't confirm counts against the letter, because "not sure" is itself what a provider will follow up on.
Result
Answer the 8 checks and the verdict appears here.
One thing no tool can do: confirm a specific document is genuine. Only the professional who signed it can do that. This checker tells you whether the letter gives them, and your housing provider, enough to work with.

What a legitimate letter is made of
The federal standard is short: when a disability or the disability-related need for an animal isn't obvious, a housing provider may ask for reliable documentation of it. That's the accommodation duty in the Fair Housing Act at 42 U.S.C. § 3604(f)(3)(B), with the documentation standard at 24 C.F.R. § 100.204. "Reliable" has a practical shape: a licensed mental-health professional who actually evaluated you, signing a letter that shows their license details and can be verified by calling them. Several states add requirements on top (a minimum provider–patient relationship, specific disclosures), so a letter that clears the federal bar can still fall short locally.
The scam end of the market fails on the same two elements every time: no real evaluation and no verifiable license. If the document came from an instant approval with no professional behind it, or it promises lifetime validity, that's the tell: however official the formatting looks. Our guides on how to get a real ESA letter, how long a letter stays current, and what to do when a landlord calls your letter fake go deeper on each.
Common questions
Can this checker prove a letter is genuine?
No. It checks the elements a housing provider is entitled to look for. That is all any checklist can do. Only the professional who signed the letter can confirm they actually wrote it, so the last step of any real verification is contacting them at the details printed on the letterhead.
Does a letter have to name my diagnosis?
No. Under the Fair Housing Act framework, a housing provider is entitled to reliable disability-related information, not a diagnosis or medical records (24 C.F.R. § 100.204). A proper letter confirms the need without disclosing the condition behind it.
Is an ESA registration or certificate the same as a letter?
No, and it isn't meant to be. The letter is the only document the housing framework evaluates, and it's the part that must come from a licensed professional who evaluated you. Cards, certificates, and registry listings are add-ons some providers offer alongside the letter; they don't replace it, and a landlord assesses the letter.
My letter failed one of the checks: what now?
A missing element is exactly what a housing provider is allowed to follow up on, and a letter missing license details or any sign of a real evaluation can be rejected. The fix is usually the provider, not the letter: ask them to reissue it with the missing element, or start over with a provider whose letters meet the standard.
