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'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. New postcards come out at least every two months. Since Penguin Mail was introduced, people can save their mail inside a "mailbox" and receive it even when they're offline.
List of Postcards

- Postcards were first released on May 19, 2006.
- It is impossible to retrieve a postcard if it has been deleted.
- The Get Better Soon postcard was removed since some penguins kept on spamming each other in an insulting manner, and as penguins do not get sick, as it is only a game.
- Before the Penguin Mail had opened, the envelope button was a buddy request and the rectangle smiley face button was a postcard.
- Puffles are able to send postcards to you if they are hungry or have run away, but it is uncertain how they do it.
- The Club Penguin Team is able to automatically send you postcards of important events.
- Starting from May 1, 2009, penguins are able to receive a 'check' monthly by being a Secret Agent or a Tour Guide. They will have 250 coins automatically added to their accounts. This is stacked up, so if you were a secret agent and tour guide, you would get 500 coins, 250 for each for job combined.
- It is impossible to get more than 92 postcards. If you get 93, the latest postcard will be deleted and you'll still have 92.
- Postcard were used to help express opinions during the 2009 Color Vote.
- Only four postcards have free items in them: the Penguin Mail postcard, the Happy Christmas postcard, the Happy Holidays postcard from 2010, and the Happy Holidays postcard from 2011.
- The 'penguin name' aspect of postcards is in text format rather than being part of the picture due to it being a variable.
- Penguins that weren't Secret Agents can still join the Elite Penguin Force by receiving a special postcard from an EPF agent.
- Non-Members can only have up to 50 postcards, however Club Penguin can add more.
- In the SWF files of the postcards, the name of what penguin sent the postcard is replaced by either "penguin888888888", "TEST NAME 123" or "undefined".
- In the SWF file of the postcard which says " _____ wants to play Treasure Hunt with you ", the name is strangely replaced by "àáâãäåæçèéêëìíîïÿþýüûúùøöõôóòñðÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖÙÚÛÜÝ".
- When your joke gets published in the Club Penguin Times, Aunt Arctic will send you a postcard so that you can know that your joke has been published.
