# Verify Phone Numbers

> Verify your personal phone numbers for test calls

## Overview

Verified phone numbers are for **non-verified businesses only** - those who haven't completed business verification ([GST & CIN compliance](/phone-numbers/buy-phone-number#business-verification)).

<Warning>
  **For Non-Verified Businesses Only:** This is your **only way** to test agents until you complete business verification and can purchase production numbers.
</Warning>

<Note>
  **Verified businesses** can test on any phone number - you don't need to verify numbers.
</Note>

**How Testing Works:**

1. Verify your phone number (via OTP)
2. Build your agent
3. Click **"Test Call"** button in agent UI
4. Agent calls your verified number
5. Test the conversation
