There's room for everyone on the Nice List! Santa's postal elves are ready to help Santa answer letters in more than 30 languages, including Braille!
There are 3 important rules when sending a letter to Santa:
Make sure to include your full return address. Santa may know where you live, but his postal elves need this information to deliver your letter!
Santa really loves to read about children’s favourite sports, jokes, school activities or family fun (even if Mom and Dad help with the writing). And, of course, he loves to get pictures and drawings from even his youngest pen pals!
Send your letter soon. December 14 is the last day to mail letters to Santa (it’s a long way to the North Pole and back!).
