NEW YORK – What do the U.S. Postal Service and Santa Claus have in common? Neither rain nor snow nor heat nor gloom of night will keep them from delivering dreams this holiday season. Today marks the start of the Postal Service’s annual “Letters to Santa” program, a campaign that’s helped fulfill the holiday wishes of children and their families for nearly a century.

“Letters to Santa” is an annual letter-writing program through which members of the public and charitable organizations respond to children’s letters addressed to Santa Claus, the North Pole and other seasonal characters. To announce that the letter adoption period has begun, a ceremony was held today at New York City’s Operation Santa command center at the iconic James A. Farley building with a special appearance by Santa Claus.

“We are delighted to once again kick off the holiday mailing season with the start of our annual ‘Letters to Santa program’,” said Postmaster General Patrick R. Donahoe. “The Postal Service is gearing up for a huge mail delivery to the North Pole to help Santa and his elves get ready for the big day.”

The Postal Service expects to deliver more than 16.5 billion cards, letters and packages between now and New Years Eve. This year, a postmark of Santa in his sleigh being pulled by six reindeer will appear in the upper right-hand corner of holiday cards and letters.

“While Santa’s been making wishes come true a bit longer than the Postal Service, for more than two centuries he’s relied almost exclusively on postal employees to bring him letters from girls and boys around the country and to help him deliver their presents,” Donahoe said. “For nearly 100 years, the ‘Letters to Santa’ program has made dreams come true for those in need. This is a time to celebrate how postal employees, charitable organizations, and businesses have made a difference in the lives of children coast to coast.”
