Hi Darrel, Our registrations are recognized in all 50 states and we have a 96% satisfaction rating. We would also like to remind you that according to the ADA, registration is not required and the only thing that is required by law to have a service dog is verbal assurance that your dog has been trained to be a service dog. Registration ID cards, certificates, tags, vests, etc are not required by law although many people find that having these materials with them makes their lives much easier as they help to avoid hassle and allow people to instant recognize your dog as a service or emotional support dog. Additionally, many business establishments, apartment complexes, and airlines require the use of registration paperwork and/or vests, tags, etc so we would advise you to check in advance about what is required.
