The Child-Safe Digital Pen Pal Platform for Real Friendships.
Stamplo is fully digital, so no physical mail or home addresses are ever shared between families. Parents stay in control while kids make connections that last. Every letter is encrypted, reviewed by you, and approved before delivery, creating safe, slow friendships across 41 countries.

Parent ID verification is required before children can send their first letter. This helps keep Stamplo a trusted, real-family community – no anonymous accounts, no strangers, just verified families like yours.
🔑 Invite Codes & Friend Finder
Children connect only if you allow it. Parents can share an 8-character Family Code with other families, or enable the Friend Finder so their child can appear in the parent-controlled search.
👀 Four-Eyes Check
Every pen pal request, letter, and image must be approved by a parent on both sides before it is delivered — so nothing is shared without your consent.
🔒 Encryption
Letters and images are encrypted in transit and at rest to protect your family's privacy.
🏅 Collect Stamps
Kids earn country-themed and limited-edition stamps with each safe exchange — sparking curiosity about the world and rewarding positive connections.
🧑🎨 Avatars & Badges
Children choose their avatar and unlock badges as they connect with new pen pals — celebrating creativity and safe exploration.
📚 Learn & Connect
Practice writing, learn about new cultures, and build real friendships — all within a parent-approved, child-safe environment.
A Growing Global Community
Children on Stamplo are writing to pen pals in the United Kingdom, United States, France, India, Canada, Japan, Germany, and 34 other countries.
Your child could be next.
