Cards and certificates are supplemental. The clinician letter is the core document.
National Service Pets offers optional ID cards and certificates for convenience, but the legally meaningful housing document is the letter issued after licensed clinical review.
ESA housing letter
The letter explains the disability-related need for an assistance animal and is used for housing accommodation requests.
ID card
A wallet-sized card can organize identifying details, but it does not replace the clinician letter.
Certificate
A certificate can be useful for records and QR verification, but it should never be presented as the only proof of ESA status.
Correct use
Use the letter for housing, and use accessories only as support.
A card can make it easier to keep identifying details organized, and a certificate can help with records. Neither should be described as the source of ESA or PSD status.
Send the clinician letter with housing requests.
Use the QR or verification path when authenticity is questioned.
Keep cards and certificates consistent with the approved letter.
What to avoid
Do not rely on accessory documents alone.
Housing providers may reject online registry certificates, animal ID tags, and cards that are not backed by current clinical documentation. A legitimate letter is the document that explains the disability-related need.
Document stack
How the pieces fit together after approval.
Primary proof
The clinician letter supports the housing accommodation request.
Quick reference
Optional cards summarize non-private identifying details for convenience.
Verification layer
The verification path helps confirm authenticity without exposing clinical records.
Use each document for its purpose
Lead with the clinician letter; treat any card or certificate as a secondary aid.
Keep your official letter available when speaking with housing providers.
Use QR verification to help confirm document authenticity.
Avoid websites that sell cards as a replacement for clinical evaluation.
Renew documents when the letter expires or circumstances change.
Is there an emotional support animal registry?
No. There is no national register of emotional support animals, and no state operates one either. Michigan does not, Texas does not, Colorado does not, Connecticut does not. If you have been searching for how to register your animal in a particular state, the reason you cannot find the official page is that it was never created.
What exists instead is a market of websites selling numbers, cards and framed certificates. Nothing they issue changes your legal position, because the entitlement comes from a professional's assessment of your need - not from an entry in a database that no housing provider is obliged to consult.
What an ESA identification card actually is
An ID card is a convenience item. It sits in a wallet, it summarises who the animal is and who you are, and it can shorten an awkward doorstep conversation with a new building manager. That is the whole of its function, and used that way it is genuinely useful.
What it is not is evidence. A leasing office assessing an accommodation request looks at the clinician's letter and verifies the licence behind it. A card is not a substitute for that document and cannot be used in place of one.
Where a card helps
Carrying a quick reference during a move. Answering a neighbour or a new site manager without producing your paperwork. Keeping the letter's reference number to hand so you can retrieve the real document quickly.
Where a card does nothing
Persuading a housing provider who has asked for documentation. Establishing that an evaluation happened. Creating any entitlement in a building that has refused the request. None of that follows from a printed card.
The vocabulary, and which word matters
Five words get used interchangeably in this market and they do not mean the same thing. Knowing which is which is most of the protection you need against being sold something worthless.
Letter
A signed document from a professional licensed in your state, issued after they assessed you. This is the only item on this list that a housing provider is obliged to consider.
Certificate
A decorative document. It generally attests to nothing verifiable and carries no legal weight. Some services issue one alongside a genuine letter, which is fine; some sell one instead of a letter, which is not.
Certification
Implies a certifying body exists. For emotional support animals none does, so the word is marketing rather than description.
Registration
Entry in a register. Since no register exists, a registration number is a number a website generated and stored on its own server.
Licence
Belongs to the clinician, not the animal. Animals are not licensed as assistance animals anywhere in the United States. When a landlord verifies a licence, they are checking the person who signed.
How to compare what these services actually sell
Strip away the presentation and every offering in this market falls into one of two categories. Either a licensed professional assessed you and wrote a document, or a website took a payment and generated one. Everything else - the lanyard, the vest, the holographic seal, the wallet card, the searchable number - is packaging around one or the other.
Three questions separate them reliably. Who signed it, and are they licensed in the state where you live? Did a real appointment take place, and could that person have declined? Can the recipient verify the signature independently rather than by visiting the seller's own website? A service that answers all three plainly is selling the first kind.
What it costs, and what you are paying for
People searching for the price of registering an animal are usually comparing against a certificate site charging a few dollars. The comparison is not like for like: one figure buys a document, the other buys a clinician's time and judgement. Amounts below come straight from current plan settings.

Start with the evaluation, not the accessory
The screening is free, takes a few minutes, and tells you whether a clinical evaluation is worth arranging. Cards and certificates can be added afterwards if you want them - but the letter is the part that does the work.
Questions about cards, certificates and registries
How do I register my emotional support animal in Michigan?
You cannot, because Michigan operates no such register. Michigan housing providers assess a letter from a professional licensed in Michigan. If a site is offering you Michigan registration, it is selling a document the state does not recognise.
Can I register my dog as an emotional support animal for free?
There is nothing to register with, free or paid. What you would need is an evaluation by a licensed clinician, and our screening stage costs nothing.
What does an ESA certificate look like?
Whatever the seller designed. Because no issuing authority stands behind them, certificates vary completely in wording, seal and layout - which is precisely why housing providers place no weight on them.
Is an ESA ID card worth having at all?
As a convenience, yes, if you find it useful for quick conversations. As documentation, no. Buy it knowing which of those two things you are getting.
How much does it cost to register a service animal?
Service animals are not registered either. Any charge described as a service animal registration fee is a payment to a private website, not to a government body.
My landlord asked for my animal's registration number. What do I say?
Tell them in writing that no register exists at state or federal level, and supply the clinician's letter with the licence details instead. That is the document they can actually verify.
Does a vest or harness give my animal any rights?
No. Equipment is not a legal status. A vest may reduce questions in practice, but it creates no entitlement and no housing provider is required to treat it as evidence.
