STD code is four or more digits that allow subscribers to dial calls fixes without any telephone operators.

  • In the first half of the 20th century, telecommunications services developed automatic systems that could connect subscribers with the use of telephone dials installed on each telephone. In the 1940s, the bell systems in the US and Canada developed methods and technologies called direct distance dialling that enabled telephone subscribers to dial long-distance telephone calls without an operator. In the UK, STD started on December 5, 1958. However, it was not until 1979 that the STD process was completed. In the UK, when Queen Elizabeth was in Bristol, she used STD by dialling Edinburgh, the farthest distance call which was directly dialled in the UK, on December 5, 1958. The technology was extended from March 8, 1963, when subscribers in London were able to directly dial Paris using international direct dialling. The term subscriber trunk dialling is used in the UK, the Republic of Ireland, Australia, India and South-East Asia. In the UK, the term is obsolescent, known as UK area codes.
