In the island ofSaint Helena and the archipelago ofTristan da Cunha, telecommunications are administered bySure Saint Helena. There is a fixed five-digit number plan, and the country calling code is +290.

Ascension Island is also part of theBritish Overseas Territory ofSaint Helena, Ascension and Tristan da Cunha, but it has aseparate calling code and numbering scheme.

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.^[1] 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.^[2]

Although Tristan da Cunha shares the +290 code with St Helena, residents have access to theForeign and Commonwealth Office Telecommunications Network, provided byGlobal Crossing.^[5] This uses aLondon020 numbering range, meaning that numbers are accessed via theUK telephone numbering plan.^[6]
