DUNS Number?

Since October 1, 2003, the Federal Government has required all applicants for federal grants and cooperative agreements, with the exception of individuals other than sole proprietors and foreign entities, have a Data Universal Numbering System (DUNS) number. The Federal Government uses the DUNS number to better identify related organizations that are receiving funding under grants and cooperative agreements, and to provide consistent name and address data for electronic grant application systems. Additional information about DUNS numbers can be found on the  D&B  web site.
