Central Contractor Registration (CCR), Legacy

The Central Contractor Registration (CCR) was the federal government's primary vendor registration database from its launch in 1998 until it was consolidated into the System for Award Management (SAM.gov) in July 2012. CCR was the mandatory registration system that federal contractors used to establish their vendor identity, provide financial data for electronic payment, and certify their business characteristics before receiving federal awards. All CCR data was migrated into SAM.gov at consolidation, and CCR no longer exists as an independent system.

What is CCR (Legacy)?

CCR was established to centralize vendor registration data that had previously been scattered across individual agency systems. Under the FAR requirements of the time, any entity seeking a federal contract was required to maintain an active CCR registration. The database captured the entity's DUNS number (the Dun and Bradstreet identifier that served as the primary entity key before the UEI system replaced it in April 2022), legal name, address, business type, socioeconomic certifications, and banking information for electronic funds transfer.

CCR was one of several legacy systems that GSA consolidated into SAM.gov as part of a broader effort to reduce the number of distinct contractor-facing federal registration and reporting portals. The other systems merged at the same time included the Online Representations and Certifications Application (ORCA), the Excluded Parties List System (EPLS), and several others. The July 2012 SAM.gov launch made CCR functionally obsolete overnight. Contractors who had active CCR records had those records automatically transferred to SAM.gov, where they became the starting point for the entity's SAM registration.

There is no action a contractor needs to take regarding CCR today. Any reference to "CCR registration" in older contract documents, agency forms, or procurement instructions should be understood to mean SAM.gov registration under current requirements.

Why it matters for contractors

CCR is relevant primarily in a historical and compliance context. Contractors reviewing legacy contract files, auditing their registration history, or responding to agency inquiries about past registrations may encounter CCR terminology. Some older agency solicitation templates and pre-award checklists that were not updated after the 2012 consolidation still reference "active CCR registration" -- in every such case, the current requirement is an active SAM.gov registration.

Understanding CCR's history also clarifies why the DUNS number appears in older contract files even though the UEI has replaced it. DUNS numbers were the CCR-era entity identifier; SAM.gov transitioned to the government-assigned UEI as part of eliminating dependency on a commercial third-party identifier.

Example

A compliance officer at a mid-size defense contractor is reviewing contract files from 2010 and finds a pre-award checklist that requires proof of active CCR registration. The officer recognizes that CCR was merged into SAM.gov in 2012 and that the company's current active SAM.gov registration satisfies what the legacy checklist was designed to verify. No separate CCR action is needed or possible; SAM.gov is the sole registration system.
