Common questions

Frequently asked questions

What is SMS verification and how does it work?
SMS verification is a security process where a platform sends a one-time password (OTP) to a phone number to confirm the user's identity. With SMSPin you receive these codes on a virtual number instead of your personal phone.
Can I use a virtual number for OTP verification on any app?
Yes — SMSPin virtual numbers work with thousands of platforms including Telegram, WhatsApp, Gmail, Instagram, TikTok, Twitter, Amazon and many more. Our blog covers step-by-step guides for each major service.
What's the difference between a temporary number and a virtual number?
A temporary (disposable) number is used once for a single OTP and discarded. A virtual number can be rented for longer and reused across multiple services. SMSPin offers both options.
Which countries does SMSPin support?
SMSPin covers 200+ countries including USA, UK, India, Germany, Brazil, Philippines, Indonesia, Nigeria and many more.
Is it safe to use a virtual number for SMS verification?
Using a virtual number is safer than using your real number because you're not exposing personal contact information to third-party platforms. SMSPin never stores your OTP messages beyond what's needed for delivery.
Does SMSPin have an API for developers?
Yes. SMSPin provides a developer-friendly REST API to programmatically request virtual numbers, retrieve incoming SMS, and automate OTP verification workflows.
