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.

• 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. Temporary numbers are primarily used to receive OTP and verification SMS when signing up for services. However, keep in mind: not all websites permit virtual numbers, so success rates may vary.

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

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