Q. My CAC is Blocked or Locked, what do I do?

CAC Issues
(2019 flyer from ITD, can be viewed from networked computers)

A CAC is blocked when:

• The user enters the wrong PIN multiple times
• There's a technology synchronization issue
• The user's certificate is corrupt

A CAC is locked when:

• DEERS or another higher level system is experiencing issues
• The user's certificate has been revoked.

Locked CAC: Call the Global Service Center (GSC) at 800-600-9332.
Blocked CAC: Go to One Stop Shop (Building 39, 3rd Fl, Room 3J13) or the NSAB DEERS / ID Card Office (Building 17, 1st floor).
