Virtual office is a term for shared office services, which normally includes business address, mail & courier services, phone services, fax services, answering services, web-hosting services, and meeting & conference facilities.

Virtual office services can provide other in-house or outsourced services such as corporate secretarial services, accounting services, or legal services. Professional firms such as law firms and accounting firms often provide registered address services as part of their service offerings.

The definition of the virtual office has also changed. Many small businesses are looking to be mobile, and even work from home, without sacrificing image. With virtual phone services, ip phone services, online fax services, mail services, and temporary office space can be a unique answer to the home based small business.

Many of the virtual office providers and temporary office providers are found in larger cities, like New York, Los Angeles, Hong Kong, etc. Due to the high popularity and prestigious addresses, major cities have become a hub for many of these virtual offices. These virtual offices are growing more popular throughout the United States.
