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.

The Sims 4: My First Pet Stuff adds seven new post cards to the collection, that can be obtained from travelling rodents. Postcards can be placed on the cork board area of the rodent cage.

Trivia

• The description of Lucky Palm's postcard is a reference to the phrase "What happens in Vegas, stays in Vegas."
• 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."
