About this app

📬 A POSTCARD APP FOR PEOPLE WHO MISS REAL CONNECTION

PostBox is a pen pal app for slow, meaningful communication. Send digital postcards to friends and pen pals around the world, no endless chats, no pressure, just a genuine hello.

Think snail mail, reimagined: beautiful postcard designs, collectible postage stamps, personal photos, and messages that feel worth waiting for.

✍️ WRITE POSTCARDS, NOT NOVELS

Choose the postcard that fits your mood.

Basic postcards give you up to 350 characters, just enough for a genuine thought, a warm hello, or a little moment from your day.

Want to say more? Writer postcards offer up to 900 characters, giving you room for stories, reflections, travel memories, and heartfelt messages.

Whether you write a few words or fill the space, PostBox lets you communicate at your own pace.

📸 TURN YOUR PHOTOS INTO POSTCARDS

Make every postcard personal. Attach your own photos to your message, or create a custom postcard with a real photo printed on the back.

Turn a favorite memory, travel moment, special place, or everyday snapshot into a postcard worth keeping.

🌍 MEET PEN PALS FROM AROUND THE WORLD

Get matched with pen pals globally and make new friends across borders. Discover different places, cultures, and perspectives through personal postcard exchanges.

Delivery times are based on real-world distance, so every postcard feels like it actually traveled. The farther it comes from, the more satisfying the arrival.

🎨 COLLECT STAMPS, POSTCARDS & DIGITAL KEEPSAKES

Discover a growing collection of beautiful postcard designs and postage stamps. Collect your favorites and build your own digital postal collection as you exchange postcards around the world.

Check in daily to earn PostBox Coins, complete activities, invite friends, and unlock exclusive postcard designs and stamps from the Store.
