MATKATAMIBA,
The only such address listed in the Participants Guide is for McMurdo, but I really think that if you substitute South Pole in the address below it will make it. The folks at the CDC that watch this stuff are great people.

You DID download the Participants Guide, did you not?

There is also guard mail, you can box stuff up and leave it for later delivery. But seriously, don’t do as most people do and send/take way more stuff down than you need, you will just mail it back home. After 3 winters maybe I finally learned that lesson, if I do it again I will pack light.
Perhaps someone else in the know will comment here…
