There is an application; sometimes mandatory schooling; some states have an online exam, others have no exam. Most states require the notary to take an oath of office that is filed with the county clerk where their commission is based; a notary bond is required in most states; then you would receive your commission document or be informed that it was prepared. Obtaining a notary stamp is the last step: some states require a written authorization certificate while others allow you to purchase one before you even filed your application.
