Our Super Mario 3D World Stamp guide will help you find every hidden stamp available in the game. It can be used for both the Wii U and Switch verions of the game. Stamps can be used to customize messages you post on Miiverse in the Wii U version (no longer in service). Choose a world below for Super Mario 3D World Stamp Locations.
Note: There are no stamps to be found in World Mushroom or World Flower.
