"Central Contractor Registration (CCR) is the primary vendor database for the U.S. Federal Government. Since October 1, 2003, it is federally mandated that any business wishing to do business with the federal government under a FAR-based contract must be registered in CCR before being awarded a contract. In addition, vendors must maintain their CCR records annually. Online Representations and Certifications Application (ORCA) replaces most of the paper based
Representations and Certifications (Reps and Certs) in Section K of solicitations with an Internet
application. FAR 52.204-8 mandates the use of ORCA on or after January 1, 2005.
CCR and ORCA are complementary systems. ORCA reuses data pulled from CCR and pre-populates many of the required Representations and Certifications. Then, the vendor completes the remaining Reps and Certs with the understanding that with each solicitation they are certifying to current, accurate and complete information."
