The country code 672 is also used for the Australian Antarctic Territory.[3] The code was also used for Christmas Island and the Cocos Keeling Islands, using area codes 2 and 4 respectively.[4] In October 1994, they were migrated to the +61 country code, under area code 091 (using exchange prefixes 62 for Christmas Island and 64 for the Cocos Islands).[5] These numbers have since migrated to the 08 9162 and 08 9164 ranges.[6]
Until 1975, country code 672 was assigned to Portuguese Timor.[7] 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.[8]
