Until September 1999, East Timor (now Timor-Leste) formed part of the Indonesian numbering plan, using the country code 62, followed by area codes for the two largest cities, Dili (390)Travel Indonesia, Volume 16, 1994, page 46 and Baucau (399).The Official Catholic Directory for the Year of Our Lord, Part 2, 1999, page 72 Following the violence in the wake of Indonesia's departure from the territory, most of the telecommunications infrastructure was destroyed, and Telkom Indonesia withdrew its services from East Timor.
In the interim, the code 672, used by the Australian External Territories, was used to reach numbers in the territory.Telstra is reconnecting East Timor to the world, Telstra, 21 February 2000 Originally, the 672 code had been allocated to the then Portuguese Timor, before its invasion and occupation in 1975.White Book, Volume 2, Part 1, International Telegraph and Telephone Consultative Committee, International Telecommunication Union, 1969, page 30
A new country code, 670, was allocated to East Timor, but international access often remained severely limited. A complicating factor is that 670 was previously used by the Northern Marianas, with many carriers not aware that the code is now used by Timor-Leste, and that the Northern Marianas, now part of the North American Numbering Plan, use the code 1 and the area code 670.
Calls to the Northern Marianas from the US are billed as calls to Timor-Leste.Saipan is not in East Timor, The Saipan Blog, December 15, 2010
