The Idaho Potato Commission

Established in 1937, the Idaho Potato Commission (IPC) is a state agency that is responsible for promoting and protecting the famous "Grown in Idaho®" seal, a federally registered trademark that assures consumers they are purchasing genuine, top-quality Idaho® potatoes. Idaho's ideal growing conditions, including rich, volcanic soil, climate and irrigation differentiate Idaho® potatoes from potatoes grown in other states.
