What is a virtual number for OTP verification?

A virtual phone number is a temporary, cloud-based number you can use to receive SMS online without a physical SIM card. When an app sends a one-time password (OTP) for sign-up or two-factor authentication, the code is routed straight to your DUAL SMS dashboard in real time.

Instead of sharing your personal mobile number with every website, you rent a disposable number for a single verification. This protects you from spam, data leaks and unwanted marketing — while still letting you complete phone verification for the services you rely on every day.

DUAL SMS covers 500+ services across 100+ countries, so whether you need to verify a new social account, a marketplace seller profile or a developer sandbox, there is a number ready in seconds.

Real, non-VoIP numbers

Our virtual numbers are sourced from genuine mobile ranges, so OTP messages from strict services like WhatsApp, Telegram and banking apps are delivered reliably instead of being blocked.

Privacy by default

Verify any app without exposing your personal SIM. Disposable numbers keep your identity, contacts and primary phone separate from third-party platforms.

Transparent INR pricing

Rent a number from as little as ₹3 and top up instantly with UPI. There are no subscriptions or hidden fees — you only pay for the verifications you actually complete.

Built for scale

From a single signup to thousands of automated verifications, a personal REST API and live dashboard let individuals and teams grow without changing tools.

How does receiving an OTP online work?

Pick a service and country, rent a number, and DUAL SMS listens for the incoming message on your behalf. The verification code appears live with a countdown — copy it into the app and you are verified. If no code arrives in time, the number is cancelled and refunded automatically.

Is online phone verification safe?

Yes. Because each number is disposable and never linked to your personal SIM, your real identity stays private. Numbers are used for a single verification and then retired, so there is no long-term trail tied back to you.

Who uses temporary phone numbers?

Shoppers protecting their inbox from spam, privacy-conscious users, QA engineers testing signup flows, and growth teams creating verified accounts at scale all rely on virtual numbers for fast, repeatable SMS verification.

FAQ

Frequently asked questions

How fast do OTP codes arrive?

Can I use the same number twice?

Each number is disposable and intended for a single verification. You can rent a new number anytime for a few rupees.
