I got this in my inbox from North Carolina Attorney General Roy Cooper. Looks legit.

A few months ago, we learned the staggering news that 26.5 million
veterans, military personnel and their families were at risk of identity
theft because their personal information was stolen from the federal
government. Although they don’t believe this personal information has
been misused, we have no way of knowing for sure.

The brave men and women whose information was stolen deserve added
protection from identity thieves who would tarnish their credit and
their good names. That’s why I pushed through a new law to allow North
Carolina military personnel, veterans and their families to freeze their
credit for free.

Here is a letter to North Carolina veterans, members of US Armed
Forces and members of the NC National Guard explaining their right to a
security freeze and a tip sheet with step-by-step instructions for
placing a security freeze on their credit. Also available is a sample
letter that can be used to request a free security freeze. I hope you
will take advantage of this opportunity and also share this information
widely with each member of your organization or association. For more

Sincerely,

Roy Cooper
