The world's first
internet number.
A permanent internet identity that lets you message, call, video chat and connect with anyone — for free. No SIM card. No telecom provider. No borders.
Real 10-digit numbers, chosen by you — currently open to India.
"Message me. Call me. Video chat with me. One number — that's all you need."
Built for the internet.
Not for telecoms.
Callibi Numbers live entirely on the internet. They're not tied to a SIM card, a mobile carrier, or a country — so the identity you build never depends on which network you're standing near.
Four steps.
One permanent number.
Getting a Callibi Number is deliberately simple — because an identity you'll use everywhere shouldn't take longer than a minute to set up.

Put it on a business card, a bio, or just say it out loud — it's yours for good.

Message, call or video chat the moment someone adds your number — anywhere in the world.
Millions of numbers.
All yours to choose from.
Every Callibi Number is a real 10-digit number drawn from the 66666–99999 series — pick one from our suggestions, or type the exact number you want.
Everything one number needs to do
Callibi bundles the essentials of modern communication behind a single identity — with the rest of the roadmap built to extend it.
Messaging
Direct messages with photos, files, and emoji between any two Callibi Numbers.
Voice Calls
Internet-native voice calling — no minutes, no carriers, no plans.
Video Calls
Face-to-face conversations powered entirely by the internet.
File Sharing
Send photos, documents and files straight through your number.
Voicemail
Leave a message when a call goes unanswered — played back right in the app.
Secure by Design
Encrypted transport, hashed credentials, and hardened sessions on every request.
Internet Identity
One number that represents you consistently across the platform.
Universal Access
Available anywhere there is an internet connection — nothing else required.
Secure by design,
honest by policy.
Every connection to Callibi runs over an encrypted HTTPS connection, the same standard your bank uses. Passwords are hashed, never stored in plain text, and never visible to anyone — including us.
One number.
Everything.
Today, Callibi handles messaging, calling and file sharing. The same number is designed to eventually become the single identity behind everything you do online.
Your number is waiting.
It takes under a minute to claim your permanent Callibi Number.
