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 with parent approval. Families can share invite codes in real life, or manage visibility in the parent-controlled Friend Finder at any time.
👀 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.

Children on Stamplo are writing to pen pals in the United Kingdom, United States, France, India, Canada, Japan, Germany, and 34 other countries.

What Parents Are Saying
My daughter found Stamplo herself as she wanted a foreign friend to write to. She's been using it for a week and is delighted every time a message arrives. As a primary school teacher, I learned English and Spanish through pen pals and it was the best way I ever found to really speak a language. I think this is worth knowing about.

Both my daughters use Stamplo and have made real friendships with children in Japan. I approve every letter before it's sent and we're travelling there this summer. Hearing them talk excitedly about Hokkaido, a place they only knew through letters, has been amazing!
