If you are trying to register or update your registration with CCR at the end of July, you will find that the site is down because it is migrating to a new site, the System for Award Management (SAM) – www.SAM.gov. For the latest information on the migration and how it may impact your interface with Grants.gov, visit the Grants.gov homepage and read "What’s New at Grants.gov."
Central Contractor Registration (CCR) is a government-wide registry that centralizes information about grant recipients and also provides a central location for grant recipients to change organizational information. Grants.gov uses CCR to establish IDs for electronic grant applicants. Please note that your CCR registration must be renewed annually.
Information for registering with the CCR and online documents can be found at http://www.ccr.gov. Before registering, you should review the Central Contractor Registration user guide at https://www.bpn.gov/ccr/doc/UserAccount.pdf.
