Starting this summer military ID cards will no longer show Social Security numbers. The process of removing SSN from the system started in 2008 when it was replaced with X from military dependent cards. After SSN being removed from visible part of military ID card it will be ruled out from scanable bar code soon after. Social Security numbers will be replaced by existing Defense Department ID numbers, 10 digit long, identifying individuals directly in DOD database. Project of phasing out SSN from military ID cards is estimated to take 4 years to complete.
