The red telephone box, a telephone kiosk for a public telephone designed by Sir Giles Gilbert Scott, was a familiar sight on the streets of the United Kingdom, Malta, Bermuda and Gibraltar.

Despite a reduction in their numbers in recent years, the traditional British red telephone kiosk can still be seen in many places throughout the UK, and in current or former British colonies around the world. The colour red was chosen to make them easy to spot.

From 1926 onwards, the fascias of the kiosks were emblazoned with a prominent crown, representing the British government. The red phone box is often seen as a British cultural icon throughout the world.[1] In 2006, the K2 telephone box was voted one of Britain's top 10 design icons which included Concorde, Mini, Supermarine Spitfire, London tube map, World Wide Web and the Routemaster bus.[2][3] Although production of the traditional boxes ended with the advent of the KX series in 1985, many still stand in Britain.

The paint colour used most widely today is known as "currant red" and is defined by a British Standard, BS381C-Red539.[4] This slightly brighter red was introduced with the K8 model in 1968, but went on to be used across the estate on previous models too. Hence, for complete historical accuracy, any kiosks in pre-1968 settings should really be painted in the previous, and slightly darker, shade BS381C-Red538
