Virtual business phone number: a direct definition
A virtual business phone number is a public number managed by an online service instead of a fixed handset. It can forward calls to an existing phone and add greetings, voicemail, transcripts, call history, or team routing, depending on the service and plan.
How a virtual business number works
Callers dial an ordinary number. The service applies your settings behind the scenes.

Local, mobile, or toll-free, depending on provider and country.
The service applies the call settings
It forwards to your phone, tries teammates, or sends the caller to voicemail.
The business keeps one public identity
Your personal number stays off your website, invoices, and listings.
What it can and can’t replace
Feature depth varies a lot between services.
A published personal number
Customers call the business line; you answer on your own phone.
Basic carrier voicemail
