Telephone numbers in Saint Helena and Tristan da Cunha

From 1 October 2013, all existing 4-digit telephone numbers on St Helena were to be prefixed by a '2' to move from a 4-digit to a 5-digit numbering plan. The change in numbering resulted from an increased demand for new telephone services and also provided a platform for the future introduction of a cellular network on the island. ==Allocations==

Although Tristan da Cunha shares the +290 code with St Helena, residents have access to the Foreign and Commonwealth Office Telecommunications Network, provided by Global Crossing. This uses a London 020 numbering range, meaning that numbers are accessed via the UK telephone numbering plan. ==See also==
