December 2006 - +290 now includes Tristan da Cunha

Tristan da Cunha is a British island territory, administered from St Helena.

British telecom regulator Ofcom announced that the St Helena +290 country code would now include telephone numbers in Tristan da Cunha, of the form +290 8xxx.

St Helena will continue to use all other +290 xxxx number ranges except the unassigned +290 0xxx.

This is a correction from a previous announcement of 15 December 2006 which indicated Tristan da Cunha numbers would be in the range +290 3xxx.
