# How to Use ChatGPT and AI Apps Without Sharing Your Real Phone Number
AI tools like **ChatGPT**, **Google Gemini**, **Claude**, and **Perplexity** have become essential in 2026 — but every one of them asks for phone number verification before you can sign up.
That single requirement is a wall for millions of users who value their privacy, travel frequently, or simply don't want marketing calls tied to their AI activity.
The good news? There's a simple fix: **a virtual OTP number**.

## Why AI Apps Want Your Phone Number
AI platforms collect phone numbers for two stated reasons:
1. **Identity verification** — to confirm you're a real person, not a bot 2. **Account recovery** — so you can regain access if locked out
But the side effect is that your real mobile number gets linked to your AI activity, your usage patterns, and potentially your real identity — even if you signed up with a throwaway email.
In 2026, with AI apps storing months of chat history and personal context, the privacy stakes are higher than ever.

## The Problem With Using Your Real Number
- **Data breaches**: AI startups are attractive targets. Your number ends up in breach databases. - **SMS spam**: Registering your number opens the door to promotional texts. - **Account linkage**: Multiple AI services can cross-reference your phone number to build a unified profile. - **Doxxing risk**: Your real phone number can be reverse-searched, exposing your identity.

## The Solution: Virtual OTP Numbers
A **virtual OTP number** (also called a temporary or secondary number) is a real phone number that receives SMS verification codes — without being tied to your identity or SIM card.
Services like **OTPStream** let you:
- Pick a number from dozens of countries - Receive the SMS verification code instantly - Use it once or multiple times - Pay only when you actually use it
No contracts. No carrier. No identity.
