ESAs are not required to have a special license number. However, your jurisdiction may require a license number for all dogs, not just ESAs. In that case, your ESA would need that general dog license.

If my docter had written a letter out to my landlord.. am i required to give them my dogs license number

You do not need to register a service animal (and service animals can only be dogs). If you only need your animals for emotional assistance, you are likely seeking an emotional support animal. Both dogs and cats are eligible to be emotional support animals. Please see this link for more information on the ESA process: https://esadoctors.com/how-to-get-emotional-support-animal/

That should be okay, Fair Housing rules allow for nurse practitioners to write ESA letters.

Hello,

My primary care physician is a Certified Psychiatric Nurse Practitioner Healthcare Provider. Can he write my letter for me? He has a medical license to prescribe my medications as his patient.

You do not need to register an ESA. A letter from a licensed healthcare professional is the only document that will qualify you to have an ESA.

Landlords can deny an emotional support animal in a few limited circumstances, such as if they determine the animal poses a health or safety risk to others. You may find this post helpful: https://esadoctors.com/faq/#ans23

Confused. Under your FAQ, you state that a landlord can not stop you from having a ESA. Which statement is true?
