Postcards are a collectible introduced with The Sims 4. The only way of collecting them all is by befriending multiple pen pals by writing them letters.
Before a Sim can write letters, however, they have to find a pen pal first. To do that, the player has to locate the "Socialize" menu point on the computer's pie menu and choose "Find a Pen Pal". Afterwards, the player can get that same Sim to check their forum post for any replies. If the Sim gets in contact with someone, a notification will confirm this. After writing a letter to their pal, the option to ask for a postcard will appear. When the option is chosen, there will be a chance that the Sim receives a postcard in the mailbox the next day.

After collecting all the base game postcards the player receives the "My Pen Pal" award, which is a plaque that can be hung on a wall.
|All your penpals discovered somehow that they know each other! What are the odds! This plaque is the result of a unanimous decision in a lengthy forums thread over what they should all pitch in to send you.||0§|
- The description of Lucky Palm's postcard is a reference to the phrase "What happens in L.A., stays in L.A.".
- The description of Dragon Valley's postcard says "Here be Dragons!", which is a medieval practice of indicating danger by putting pictures of dragons and sea monsters on maps.
- The description of Sixam's postcard is reversed, as much as Sixam is reversed of Maxis.
- The reversed description is: "Welcome to Sixam! Hold on to your butts."
