The holiday spirit is officially underway as USPS Operation Santa opens for its 113th year, inviting kids and families to send letters to Santa starting now. Letters must be postmarked by December 6th to be eligible, and this year participants can even adopt an entire family’s letter to make more wishes come true at once. Beginning November 17th, adopters will also have access to an expanded online gift catalog, making it easy to shop and ship directly. With thousands of requests expected, the program is encouraging more helpers than ever to step up and spread holiday cheer across the country.
