Listen to the Story.

The US Postal Service has announced it plans to stop delivering mail on Saturdays. The financially struggling agency says the move could help it save as much as $2 billion a year.

But it could delay letters a bit. Of course that delay might not matter all that much if you're sending a letter to one of the country's most remote neighborhoods: for instance, the South Pole.

Yes, there is a US Post office at the South Pole. It's located at the Amundsen-Scott South Pole Station.

Letters sent there go by way of New Zealand where they're loaded onto US military cargo planes bound for Antarctica.

And believe it or not, the place has its own zip code.

For Wednesday's Geo Quiz, what's the zip code for the South Pole?

The zip code we're looking for is not 90210.

That of course is reserved for ritzy Beverly Hills.

Nor is it 12345 which belongs to General Electric, in Schenectady, New York.

Then there's ours here at The World newsroom in Boston, 02135.

Nope, the one we're looking for is at 90-degrees latitude South, at the southernmost post office in the world.

The zip code for the Amundsen-Scott South Pole Station is an undistinguished 96598.

Duffel bags of letters to 96598 travel to the South Pole via New Zealand on US military cargo planes usually stuffed in between scientific gear and vital supplies.

Of course deliveries can be unpredictable. Depending on the weather and logistics, packages can take up to six weeks. We haven't heard yet on whether the ending of Saturday deliveries will be enforced at the South Pole.

One more thing.

Do not use foam peanuts. Styrofoam is banned on the frozen continent.
