You can have your letter answered by Santa Clause himself.
Old Saint Nick and his helpers are now answering Christmas letters from children around the world.
The letters are sent to a special post office in the German town of Himmelpfort.
The letter on the longest journey so far comes all the way from South Africa.
All letters received between now and December 16 will be personally answered by Santa or one of his helpers.
To write to Santa, address your letter to An den Weihnachtsmann, Wihnachtspostfiliale, 16798, Himmelpfort, Germany.
A return address is required.
