A telephone booth, telephone kiosk, telephone call box, telephone box or public call box is a tiny structure furnished with a payphone and designed for a telephone user's convenience; usually the user steps into the booth and closes the booth door while using the payphone inside. In the United States and Canada, "telephone booth" (or "phone booth") is the commonly used term for the structure, while in the Commonwealth of Nations (particularly the United Kingdom and Australia), it is a "phone box". Such a booth usually has lighting, a door to provide privacy, and windows to let others know if the booth is in use. The booth may be furnished with a printed directory of local telephone numbers, and a booth in a formal setting, such as a hotel, may be furnished with paper and pen and even a seat. An outdoor booth may be made of metal and plastic to withstand the elements and heavy use, while an indoor booth (once known as a silence cabinet) may have more elaborate architecture and furnishings. Most outdoor booths feature the name and logo of the telephone service provider.

To use it, one had to buy paper tickets called Telefonbillet which allowed for a few minutes of talking time. In 1899, it was replaced by a coin-operated telephone. William Gray is credited with inventing the coin payphone in the United States in 1889, and George A. Long was its developer. The first telephone booth in London, England, was probably installed near the Staple Inn in High Holborn in May 1903. In the UK, the creation of a national network of telephone boxes commenced in 1920 starting with the K1 which was made of concrete, however the city of Kingston upon Hull is noted for having its individual phone service, Kingston Communications, with cream coloured phone boxes, as opposed to classic royal red in the rest of Britain. Also, The Post Office was forced into allowing a less strident grey with red glazing bars scheme for areas of natural and architectural beauty. Ironically, some of these areas that have preserved their telephone boxes have now painted them red. Design Starting in the 1970s, pay telephones were less and less commonly placed in booths in the United States. In many cities where they were once common,
