Canada Post has a special postal code for letters to Santa Claus, and since 1982 over 13,000 Canadian postal workers have volunteered to write responses. His address is: Santa Claus, North Pole, Canada, H0H 0H0; no postage is required. (see also: Ho ho ho). (This postal code, in which zeroes are used for the letter "O", is consistent with the alternating letter-number format of all Canadian postal codes.) Sometimes children's charities answer letters in poor communities, or from children's hospitals, and give them presents they would not otherwise receive. From 2002 to 2014, the program replied to approximately "one million letters or more a year, and in total answered more than 24.7 million letters"; as of 2015, it responds to more than 1.5 million letters per year, "in over 30 languages, including Braille answering them all in the language they are written".
