Until 1975, code +672 was assigned to Portuguese Timor. When that territory was annexed by Indonesia in 1975, it used the Indonesian country code +62 and the area code 390. However, following the end of Indonesian rule in 1999, the code +672 9 was used under an interim arrangement to reach numbers in the territory.
