Service dog certification is not required in the United States, and there is no government body that certifies service dogs. Under the ADA a dog is a service dog because it is trained to do a task for a person with a disability, not because it holds a certificate, and the Department of Justice says certificates sold online "do not convey any rights under the ADA". What does exist is real training, the DOT form airlines use, and a handful of voluntary state tags.
Is service dog certification required?
No. The federal rule for businesses says it in plain terms: a business "shall not require documentation, such as proof that the animal has been certified, trained, or licensed as a service animal" (28 CFR 36.302(c)(6)). State and local governments are bound by the same words in 28 CFR 35.136(f).
The Department of Justice also chose not to create a certification system when it wrote the 2010 rules. The preamble says DOJ "will not impose any type of formal training requirements or certification process". And its FAQ answers the owner training question directly: "People with disabilities have the right to train the dog themselves and are not required to use a professional service dog training program."
So the two things that make a dog a service dog are a handler with a disability and a dog that is individually trained to do work or perform tasks for that disability. See service dog requirements for the full checklist.
Who certifies service dogs? Nobody, federally
No federal agency certifies, registers or licenses service dogs, and no private company can do it on the government's behalf. The DOJ is blunt about the websites that sell certificates:
"There are individuals and organizations that sell service animal certification or registration documents online. These documents do not convey any rights under the ADA and the Department of Justice does not recognize them as proof that the dog is a service animal."DOJ ADA service animal FAQ, question 17
That answers most of the searches around this topic. "Service dog certification online" is a private document. "ADA service dog certification" does not exist, because the ADA has none. "Can you buy a service dog certificate?" Yes, anyone can sell you paper, but buying one does not change what your dog is. For the registry side of the same myth, read service dog registration: is there an official registry?
Do you need certification to fly? What airlines actually require
No. For flights, the only documents a U.S. airline may require are the U.S. Department of Transportation Service Animal Air Transportation Form and, for flights of eight hours or more, the relief attestation. The rule says airlines are "not permitted to require documentation from passengers with disabilities traveling with service animals beyond the completion of the forms" (14 CFR 382.75).
Airlines say the same about certificates. Southwest's help page: "A service animal vest, harness, ID card, or registration certificate will not be accepted in place of the form." Delta answers a question about one registry's members with "Our policies and procedures still apply to customers with NSAR memberships."
The DOT form asks for the name of the task trainer or training organization and warns that knowingly false statements on it are a federal crime (18 U.S.C. 1001). Owner training is allowed; you name yourself. Step by step: how to fill out the DOT service animal form.
Program graduation papers and trainer letters: what they are worth
Dogs from training programs usually come with paperwork. It is a genuine record of training, and it can matter in a few places, but it is still not a legal pass in a store or restaurant:
- Accredited programs. Assistance Dogs International accredits training programs, not individual dogs. Its standard defines an assistance dog as trained "to do three or more tasks". That is ADI's accreditation rule; the ADA sets no minimum number of tasks.
- Work. Employment is different from public access. When the need is not obvious, an employer "may ask the individual for reasonable documentation", and the Job Accommodation Network says an owner-trainer "can be asked to document or demonstrate that the service animal is in fact appropriately trained".
- Flights outside the U.S. Several foreign carriers, including Air Canada, Aer Lingus, Lufthansa, British Airways and Air France, ask for a trainer-issued ID card or certificate on non-U.S. routes. That means papers from the organization that trained the dog, not an online registration.
AKC Canine Good Citizen and public access tests: useful, not legal status
The AKC Canine Good Citizen test is a ten-skill manners test open to any dog. It is a good foundation, and the AKC is clear about what it is not: "Dogs are not service dogs simply because they passed the CGC test and they do not have special access rights in public places (stores, restaurants, planes, etc.). Service dogs must also be trained on tasks specifically related to the person's disability."
Public access tests are benchmarks, not licenses. The ADI Public Access Test is reserved for ADI member programs, and ADI says permission to use it is "NEVER granted to individual trainers". IAADP publishes minimum training standards (at least 120 hours over six months or more, with at least 30 hours of outings) and adds that failing them "does not mean the dog is not a legitimate assistance dog under the Americans with Disabilities Act". More in the service dog public access test.
States that issue service dog tags
A few states and counties do issue something, and every one is voluntary for public access:
- California: county animal control issues assistance dog identification tags to trained guide, signal and service dogs (Food and Agricultural Code 30850). California trainers taking a dog in training into public places must have the dog on a leash and tagged with one (Civil Code 54.2).
- Michigan: the Department of Civil Rights offers a voluntary ID and patch (MCL 37.303). Access cannot be conditioned on it.
- New Hampshire: a state tag exists, and the statute says those tags "shall not be used to verify the legitimacy or authenticity of a service animal for any purpose" (RSA 466:8).
- Maryland: an orange state "service dog" tag comes with the fee-waived dog license. North Carolina law provides a state registration tag, though whether the agency still issues it could not be confirmed.
None of these is required to enter a business, and a private certificate must never be made to look like one.
Does service dog certification expire?
There is no official certification, so there is nothing official to expire or renew. What does run on a clock is practical: the DOT form is filled out per trip, and some airlines keep a reusable approval. American Airlines, for example, issues a Service Animal ID after you submit the form and says it "will expire when the animal's vaccination expires". Your local dog license and rabies vaccination also expire, and service dogs are not exempt from those rules.
Red flags when a site sells "certification"
- Words like "official", "certified", "ADA registered" or "federally recognized". None of those exist for service dogs.
- Government seals, eagles or agency names. Implying a government connection is an unfair or deceptive practice under the FTC Impersonation Rule (16 CFR 461.2), and HUD told the FTC in 2019 it had found a site using HUD's seal without authorization.
- Countdown timers or warnings that the law is about to change. A 2026 class action, Goven v. Support Pets, alleges exactly that kind of pressure alongside certificates and ID cards with "no legal significance". It is pending, with no outcome reported.
- A quiz that says you "qualify". No quiz can decide whether you have a disability or whether your dog is trained.
More warning signs in are service dog registries legit?
What we sell instead, and what it is not
We do not certify dogs, and we do not test them. Our voluntary registry keeps a record you fill in yourself: a registration number, a lookup page, a digital ID card and an emergency contact. It costs a one-time fee and gives no legal rights. Our printed registration certificate is a keepsake, and it says in print that it is a voluntary private registration and not a certification of training.
Common questions
Do service dogs have to be certified?
No. Federal rules bar businesses from requiring proof that a dog is certified, trained or licensed, and DOJ chose not to create any certification process.
Can I get my dog certified as a service dog online?
You can buy a document online, but the Department of Justice says those documents do not convey any rights under the ADA and are not proof that a dog is a service dog.
How much does service dog certification cost?
Legally, nothing, because none is required. The real cost of a service dog is training.
Does the AKC certify service dogs?
No. The AKC Canine Good Citizen is a manners test, and the AKC says passing it does not make a dog a service dog or give it access rights.
Can a business ask to see my dog's certification?
No. Staff may ask only whether the dog is required because of a disability and what task it is trained to perform. See what businesses can ask.
Do I need certification for my service dog to fly?
No. U.S. airlines may require only the DOT Service Animal Air Transportation Form, plus the relief form on flights of eight hours or more.
