What is the difference between my primary practice location, mailing address and additional practice location?

Primary practice location is the physical location where you practice the majority of the time. Mailing address can be a post office box or street address. The mailing address is where the Board will mail any correspondence. Additional practice location is a practice location other than your primary practice location. It may be a hospital or a clinic in another state. Your primary practice may be in another state and your additional practice location may be in Mississippi.
