It's a name that needs no address.Everyone knows Santa Claus lives at the North Pole.
So letters sent to Santa Claus find their way to the small town of the North Pole deep in Alaska，including those simply sent to Santa. Last year，120,000 letters arrived from 26 countries，not including the thousands with no return addresses.

Those who have return addresses usually get a reply and a North Pole postmark（邮戳） that has delighted children all over the world for many years. They feel happy to receive Santa's reply.
Letters arrive all the year around in the town of 1,600，where streets have names such as Santa Claus Lane and Kris Kringle Drive. Around Thanksgiving，they start getting there by the thousands each day as Christmas comes. Even letters without stamps get through，an exception（例外）for the U．S. Postal Service.
“This is special because it has Santa's name on it，”said Debra Cornelius，an officer at the main post office in nearby Fairbanks，where the letters are kept during the holiday.
Gabby Gaborik is among several dozen volunteers who are busy sending off replies to children who sent return addresses.
In his 10 years as a volunteer，Gaborik has seen every kind of wish. There are children who want the latest toys they see on TV. There are children who ask for miracles（奇迹），some wanting their mother back for Christmas or their father back from Iraq，even though he died there.
Replies get a North Pole postmark，including a halfmoon drawing of Santa's face. Even late letters get a reply，Gaborik said，“It says something like ‘Thanks for writing. Santa's been really busy，’anything the children might want to hear，”he said.
