What Are Virtual Numbers?

Virtual numbers, also known as online numbers or cloud numbers, are telephone numbers that aren't directly associated with a physical telephone line or SIM card.

These numbers operate over the internet using Voice over IP (VoIP) technology, allowing you to make and receive calls and SMS messages through web interfaces or mobile apps rather than traditional phone hardware.

Cloud-based phone numbers

Key Difference: Unlike traditional numbers tied to specific devices, virtual numbers exist in the cloud and can be accessed from anywhere with an internet connection.

Types of Virtual Numbers

  • Temporary Numbers: Short-term use for verifications
  • Rental Numbers: Longer-term number rentals
  • Toll-Free Numbers: Free for callers to contact
  • Local Numbers: Specific area codes
  • International Numbers: Numbers from other countries

Common Use Cases

  • SMS verification for online services
  • Business communications
  • Privacy protection
  • International business presence
  • Marketing campaigns
