Postcards are cards that can always be sent to other players, and bought for 10 coins each, in the Postcard Catalog. The categories for postcards are invitations and encouragements. Some postcards are related to Club Penguin Rewritten's theme for the month. Other invitations include the Pizza Parlor, the Coffee Shop, the Dance Club, the Snow Forts, the Ice Rink, Sled Racing, the Ski Lodge, Mancala, Cove, and Find Four.
On February 3, 2020, an update was made which removed the delay when switching between postcards. Additionally, the player is no longer taken back to the beginning of their postcard list if they remove a postcard.
