How to get a letter postmarked from the North Pole

We recommend sending your letters between November 1 through December 2. When responding as Santa, make the letter from Santa as personal as possible by highlighting your child’s accomplishments over the past year. For example, helping around the house, receiving good grades in a particular subject at school or participating in community service activities. This is a great activity for Thanksgiving that the whole family can enjoy, including parents, grandparents, aunts, uncles and other caregivers.
