All service dogs in New York City must have a valid dog license issued by the City's Department of Health. You may also request, free of charge, a tag that identifies your dog as a service dog.

The tag is optional and businesses open to the public, including restaurants, must allow access to a service dog whether or not the dog is wearing a service tag. You must meet certain requirements to obtain the tag.

Businesses may not demand any proof of disability or certification of the animal to allow a person to access the business with their service animal.
