South Pole personnel line up on a stairway outside the station to hand up package mail. The station relies on volunteers to run its postal operations.

Proper postage

Follow the rules to receive philatelic mail from Antarctica

Philatelists may obtain a maximum of two covers (self-addressed stamped envelopes) a year by writing to the postal clerks (addresses below) at the three year-round U.S. Antarctic stations. (Note that Palmer Station External U.S. government site doesn’t have its own post office. Cancels are handled in Punta Arenas, Chile.)

For further guidelines, consult the official National Science Foundation philatelic mail page External U.S. government site.

Covers will be processed for personal (i.e., noncommercial) use of individuals only. U.S. correspondents use domestic first-class postage for the APO addresses (below) and international first-class or airmail postage for the Palmer Station address. Non-U.S. correspondents use international first-class or airmail postage.
