Antarctica does not have a country code of its own. Several countries operate research bases in Antarctica, with a variety of different numbers.
For example:
Australian bases use +672.
New Zealand's Scott Base uses +64 2 409.
U.S. bases generally use satellite telephones in codes depending on the satellite provider.
(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.).
