The Benefits
Step-by-step secure phone verification
Phone Collection
Users submit their phone number for secure verification.
OTP Generation & Delivery
A unique one-time passcode is generated and sent via SMS to the user.
Code Validation
The user enters the received OTP to confirm phone number ownership.
How it Works
OTP Validation & Risk Analysis
The user enters their phone number, and our system delivers a secure, time-sensitive One-Time Passcode (OTP) via SMS. The user enters the code to prove possession of the SIM card. Simultaneously, we perform a risk analysis on the number itself, checking its line type (e.g., mobile vs. VoIP/virtual) and other carrier-level data. The final result, combining OTP validation and risk intelligence, is delivered instantly via webhook or API.
