Letters postmarked from the North Pole are still possible through the United State Postal Service.
Holiday letters and cards are stamped with “Santa” as the sender.
In order to have the letter postmarked and delivered by Christmas, they must arrive at the post office in Anchorage Alaska by Monday, December 10th.
Place a card or letter from Santa in an envelope with a First Class mail stamp and with the return address “Santa, North Pole.”
Place the items in a larger envelope with the correct postage and send it to:
