2013 change to numbering plan[edit]

From 1 October 2013 all existing 4-digit telephone numbers on St Helena will be prefixed by a ‘2’ to implement a 5-digit numbering plan.[1] The change in numbering resulted after the increased demand for new telephone services while also providing a platform for the future introduction of a cellular network on the island.[2]

Tristan da Cunha[edit]

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.[4] This uses a London 020 numbering range, meaning that numbers are accessed via the UK telephone numbering plan.[5]
