After more than 40 years without a change, Army dog tags will have the Social Security numbers replaced with a random 10-digit Department of Defense identification number.
The change comes six months after the Office of Personnel Management admitted that 21.5 million people, mostly federal and military employees, had their Social Security Numbers stolen by Chinese hackers. The OPM and the DoD established a service for monitoring the credit of people affected by the hack.
The new DoD identification numbers are being slowly implemented across the military as an attempt to prevent identity theft. The numbers are randomly generated as they are assigned.
New ID cards already carry the DoD number instead of a Social Security number and TRICARE is switching soon, according to an Army spokesman.
No Chinese hackers were available to comment on how this will affect their bulk data collections. It will certainly reduce their ability to collect them one at a time.
