You receive a postcard whenever you open up a gift from a friend in Pokémon Go. The postcard is a small icon and image of the PokéStop your friend visited, marking a location they went to while playing Pokémon Go in their part of the world. You can save some of them to a Postcard Book, and if you do, there’s a good chance you might encounter a Scatterbug from that region of the world, giving you access to a Vivillon from that habitat. Here’s what you need to know about how to pin postcards to your Postcard Book in Pokémon Go.

How pinning postcards to your Postcard Book works in Pokémon Go

The option to do this will happen briefly when you initially open up a gift from a friend. When opening a gift, make sure you have room for additional items in your inventory. You may need to discard unwanted items from your Pokémon Go inventory if it’s full before you can accept a gift. Once you accept a gift, there is a small pin icon next to the postcard, and you will need to click this to post it to your Postcard Book. Again, this happens before you open the gift.
