What is a Virtual Phone Number?

A virtual phone number is a cloud-based phone number that is not tied to a physical SIM card, phone line, or geographic location. Calls and SMS to a virtual number are routed over the internet to whichever device the user configures — a mobile app, desktop softphone, traditional phone, or another phone number.

How a Virtual Phone Number Works

Virtual numbers are issued by VoIP providers who hold blocks of phone numbers across regions. When someone calls or texts the number, the provider routes the communication over internet protocols to the user’s chosen endpoint — a mobile app, web app, or even another phone number.

Common Virtual Phone Number Use Cases

• Business lines — Separate work and personal calls without a second SIM
• International presence — Use a local number in a country where you don’t live
• Marketing — Track calls from different ad campaigns to different numbers
• Customer support — Route calls through an IVR menu to the right department
• Privacy — Share a number that doesn’t reveal your real cell
• SMS verification — Receive 2FA codes for services you don’t want tied to your real number
