At the end of July 2012, access to the Excluded Parties List System (EPLS) was taken over by a new system. EPLS, along with Federal Agency Registration (FedReg), the Central Contractor Registration (CCR), and the Online Representations and Certifications Application (ORCA), were migrated into the new System for Award Management also known as SAM (https://www.sam.gov/portal/public/SAM) At this time, SAM is overwhelmed and record searching on the EPLS is still available at https://www.epls.gov/. Indications are this search feature will eventually be moved to SAM
Other free search federal government sites commonly used in background investigations remain unchanged, including:
Denied Persons List - www.bis.doc.gov/dpl/default.shtm
Unverified List - www.bis.doc.gov/enforcement/unverifiedlist/unverified_parties.html
Debarred Parties List - www.pmddtc.state.gov/compliance/debar.html
