Mobile number verification
Know your user's mobile number — without asking.
The phone's own carrier confirms the number over mobile data. No SMS code and no typing.

Less friction at sign-up
Catch fake or mistyped numbers and SIM-less impersonation without an OTP cost or delay. Verification runs silently while the user stays in your app.
Built with a clear boundary
Zuvio never stores the phone number. Usage events record the result, failure reason, and requested host. On Wi-Fi, or outside supported carriers, the response is empty so your app can use its normal flow. Carrier support currently includes Airtel Kenya.
