A new way to communicate with people you don't know fully yet. A new contractor. A buyer from Facebook Marketplace. A match on a dating app. Someone you met at a conference. Every time you share your phone number with someone you don't fully trust yet, you're taking a risk you can't undo. That's because your phone number is connected to almost everything important — your bank accounts, your credit cards, your online logins, your identity. It's as sensitive as a bank account number. And once you've given it out, you can't take it back. Why your phone number is risky to share Phone numbers are "open by default." Anyone who has your number can call or text you whenever they want. If a stranger turns out to be a spammer or scammer, they can flood you with calls, try to trick you, or sell your number to others — and there's nothing you can do about it. Meet Tnumber Tnumber is your personal contact number— a permanent number in the format T XXX XXX XXX that you share instead of your phone number. Unlike a phone number, Tnumber is closed by default. Nobody can reach you unless you approve them first. When someone wants to contact you, they send a Contact Request. You decide: accept it, or don't. That's it. What you get No spam, ever. People must get your permission before they can contact you. Unwanted callers never get through. Free calls worldwide. Talk to friends and family anywhere in the world at no cost. You're always in control. Approve the people you want to hear from. If you change your mind later, you can Revoke Contact and remove their permission anytime. Not tied to your identity. Your Tnumber isn't linked to your ID, your bank, or your personal documents. It's just a safe way to communicate. One permanent number. You get a single Tnumber that's yours to keep — not a throwaway or burner number. How it works Download the app and get your Tnumber. Share your Tnumber instead of your phone number. When someone wants to reach you, you'll get a Contact Request. Accept the people you want to talk to. Ignore the rest. Make free calls anywhere in the world. Changed your mind about someone? Revoke their access anytime. Where to share your Tnumber Share your Tnumber instead of your phone number in the situations where it matters most: Working professionals — doctors, lawyers, actors, and others who need a work line separate from their personal number Marketplaces & classifieds — Craigslist, OLX, Facebook Marketplace, and other buying-and-selling sites Dating — Tinder, Bumble, Hinge, and other apps where you want to connect without handing over your real number Temporary trust — contractors, Airbnb hosts, and one-off services you deal with briefly Networking events — conferences, meetups, and hackathons where you swap contacts with new people AI agents & characters (experimental) — AI friends, avatars, and assistants In-person & retail (coming soon) — stores, salons, clinics, and restaurants Because Tnumber is closed by default, you can share it in any of these situations without worry. The other person can't spam you and can't reach you without your okay. Your privacy comes first Calls are secure and encrypted Your personal information stays private You control who can contact you — always We never sell your data Get Tnumber today. Share it with confidence. Stay in control.
