2013 change to numbering plan

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]
