How can I check on the status of my security clearance investigation

For DoD clearances only your security officer may inquire about the status of your security clearance application. This can be done by checking the Joint Personnel Adjudication System (JPAS), the Defense Information System for Security (the replacement for JPAS) and/or the Security and Investigations Index (SII) or by telephoning the DoD Security Service Center at 888-282-7682. Applicants can check the status of their OPM background investigation by telephoning 724-794-5612 or 202-606-1800.
