Santa's Address

The official Canadian address for Santa Claus uses the postal code of H0H 0H0, cleverly matching the jolly one's famous laugh.  Eleven thousand "postal elves",  volunteers from Canada Post, respond to more than one million children's letters to Santa, answering each one in the language or in which it was written.
