How do I verify whether or not a NACI (or equivalent) has already been completed on an existing employee or contractor?
Authorized personnel security offices may get this information directly from the OPM investigations database. If an agency’s personnel security office does not have access, they should contact OPM’s Agency Liaison Group at 703-603-0442. Additionally, older “Official Personnel Folders” contain SF-86s and SF-171s bearing a stamp which usually reads “Investigated to 10450 standards”. Agencies may take this as evidence a NACI was completed”.
