VCSS is a voluntary participation program; however any vendor desiring to participate must have a valid UEI and must register in the System for Award Management (SAM).
The Central Contractor Registration (CCR) database has been consolidated into SAM, along with other federal procurement systems and the Catalog of Federal Domestic Assistance. Please visit
www.sam.gov for more information on what former CCR registrants need to know and how to register for SAM.
Vendors who need a new UEI can contact SAM

.
SAM also requires Login.gov as a two factor authenticator.
