For more than 100 years, the United States Postal Service has been helping families in need experience a happy holiday season through their 'Operation Santa.'

Its simple: Families and children wishing for a gift can write a letter to Santa, stamp it and send it to the "North Pole." Others will adopt a letter and send gifts to the families in need.

The USPS said in a press release, "You don’t have to be religious or even believe in Santa to participate."

The program began accepting letters Nov. 1. and letters are still being accepted. The deadline is for letters to be postmarked by December 10th.

The USPS is also putting out the call now for adopters to help fulfill these wishes. Businesses and other organizations can also get into the spirit of the season by forming teams to adopt letters. Adopters can read through the letter, pick one and then make a child's wish come true.

All adopters must go through a verification process. Letters can be adopted through Dec. 22nd and packages can be shipped until Jan. 14th.

More details on the adoption process can be found, here.

Those with a wish can send letters, not an email, to Santa’s official workshop address:

Santa Claus

123 Elf Road

North Pole, 88888

 The letters must be stamped and the USPS reminds families, like Santa, be sure to check your letter twice to make sure it includes a full return address.
