A temporary phone number, often referred to as a virtual or disposable number, is a number that isn’t permanent and is meant for short-term use. It lets you receive SMS, get OTP codes, or quickly finish registrations without needing to share your actual number. These numbers are usually shared by multiple users and can expire shortly after being used.

Fake phone numbers help safeguard your actual phone number from spam, scams, and potential data exposure. Ideal for

• Signing up anonymously
• One-time SMS verification
• Testing platforms or services
• Avoiding promotional messages after registration

A temporary number is typically short-lived and may be shared among users, whereas a virtual phone number can be used for both short-term and long-term purposes, and provided exclusively. Both enable SMS, OTP, and verification code reception.

Absolutely. Our long-term virtual numbers can be used with apps that require your sensitive information or when you need permanent access to those apps. Once you’ve rented a number, it is assigned to you exclusively, and no one else can use it. You can easily receive OTPs and SMS messages on that number anytime you need.

There are several possible causes:

• The number reached its SMS limit
• The service you’re registering with blocks virtual numbers
• The message got delayed or wasn’t delivered
• The temporary number expired before receiving the message
• The sender failed to dispatch the OTP
• Some services might block you if your actual location doesn’t match the location of the phone number. In such cases, we recommend using a VPN or proxy from the country you’re trying to register in

If this happens, we recommend trying a different number or refreshing the list.

Our numbers are designed specifically for receiving SMS online. They include both VOIP (free) and non-VOIP (premium) options. While often referred to as "fake numbers," they function perfectly for verification purposes on websites—helping you sign up without exposing your real identity.

Not at all. Second Number is also a PWA (progressive web app), so you can use it in your device’s browser without downloading or installing anything. But if you want to upgrade your options and place calls using a rented number, you can download our app.

VoIP numbers are internet-based phone numbers that many platforms—like Tinder, PayPal, Venmo, Telegram and others—tend to block. In contrast, non-VoIP numbers are tied to physical SIM cards and function just like standard mobile numbers. Because of this, non-VoIP virtual numbers are widely trusted and accepted across virtually all online services.
