Of the billions of letters sent to Santa each year, most of them come from France. An incredible 1.7 million letters are written to the jolly old elf from the good boys and girls of France. Canadian kids send 1.35 million letters to him (using postal code H0H 0H0). Just over one million letters show up at the North Pole from children in America. Mexico and Latin America aren’t even on the list, but this may be because kids in those countries don’t send letters to Santa. They put their letters in helium balloons and release them.
