Common Access Card (CAC)
Appointment Site

DARPA has the authority to issue the Common Access Card (CAC) to DoD Civilian personnel and DoD Contractors. This appointment website is for the DARPA CAC office only; we can not reserve times for you at any other office. Please use the following link if you need to locate an office in your immediate area: http://www.dmdc.osd.mil/rsl/appj/site?execution=e1s1

The DARPA CAC issue office is located at 675 N. Randolph Street, Arlington, VA. Upon entering the building please proceed to the Visitor Control Center (VCC). Due to the length of processing time required (approximately 20 minutes); CACs are issued by appointment only. Appointments are scheduled through this website. This website also contains instructions and forms necessary for processing and lists the forms of identification that must be presented at the time of issue. Due to limited parking availability, unfortunately there is no parking available on site or along the street at DARPA. We recommend that you use the Ballston Public Parking Garage conveniently located directly across from our front entrance. The cost is $1 for the first three hours.

To update your CAC Personal Identification Number (PIN), please schedule an appointment and select "Change Pin" from the drop down, no additional identification or paperwork is required.

DARPA is not a full service DEERS facility. DARPA does not issue retired military, retired DOD or dependent I.D. cards. Please contact your servicing military personnel office:
