Unfortunately, the US Postal Service no longer supports programs such as “Any Service Member or Any Wounded Warrior” that allow organizations to send items to any service member. This practice is prohibited due to the risks facing deployed military forces.
Previous programs that allowed people to send mail to service members unknown to them were discontinued following the terrorist attacks of 2001. This includes the “Any Service Member, Any Wounded Warrior, Any Soldier, Sailor, Airman or Marine” mail program for military personnel. Mail to “Any Service Member” will not be delivered.
