A virtual office is a service that allows businesses and individuals to use a business address and services such as mail forwarding, call answering, and conference rooms without actually renting a physical workspace. This can be particularly useful when a business or individual does not need a physical presence in a specific location, or cannot or does not want to afford expensive rent or long-term leases.

A virtual office can also be used as a professional business address to improve a company's image and increase its credibility by displaying it as a central place of business. It can also be used as a temporary solution until a company or individual finds a permanent office or job.
