What is a DUNS number and why is it being requested?
The Dun and Bradstreet Universal Numbering System (DUNS) provides numbers to employers upon request as assigned by Dun & Bradstreet. It is standard for all U.S. Federal Government electronic commerce transactions. Employer submission of this number assists in identifying Federal contractors and subcontractors. An employer may request a DUNS number at no cost by calling Dun & Bradstreet at 1-800-333-0505.
