The 2013 Holiday Mail for Heroes program is underway, meaning that Americans who wish to send a holiday card to a service member can easily do so with the help of the American Red Cross.

Until Dec. 6, the Red Cross invites the public to send messages of thanks and holiday cheer by mailing them to:

Holiday Mail for Heroes
P.O. Box 5456
Capitol Heights, MD 20791-5456

Red Cross volunteers across the United States and on military installations overseas sort and deliver the cards throughout the holiday season.

The Red Cross has received and distributed more than 6.5 million cards for members of the U.S. Armed Forces, veterans and their families since the program started in 2006.
