Santa's mailbox is now open, and letters are being accepted as part of Operation Santa. The program, run by the USPS, allows individuals and groups to adopt and respond to letters sent to the North Pole.

Registration to adopt letters will begin on November 2, with the adoption window opening on November 16. To be eligible for adoption, letters must be postmarked by December 5 and follow the program guidelines.

Further details about the program, including guidelines for submitted letters, are available at USPSOperationSanta.com. This program provides an opportunity for generous individuals and groups to bring joy to families during the holiday season.
