GO Stamp Rally (Japanese: GOスタンプラリーGO Stamp Rally) is a location-based activity in Pokémon GO where Trainers are rewarded stamps at specific PokéStops or Gyms. Designated PokéStops or Gyms are indicated by a stamp icon, and spinning the Photo Disc will trigger the stamp event. Pressing the stamp for longer will increase the density of the ink. Progress of the Trainer's Stamp Rally card can be tracked in the Scrapbook, and collecting stamps can unlock item rewards and Pokémon encounters.
