DUNS Number Guide Government Vendors

Data Universal Numbering System (DUNS) Number:
The Data Universal Numbering System (DUNS) number is a unique nine character identification number provided by Dun & Bradstreet (D&B).
The DUNS Number is site-specific and division specific. Therefore, each physical location of an entity will have its own DUNS Number. Further, each separate division or branch of an entity will have its own, unique DUNS Number. Through DUNS Number linkage, these unique DUNS Numbers will roll up to the Headquarters or Office level that oversees the branch or division.
Business entities, self-employed individuals (doctors, lawyers, etc. who are engaged in a specific business activity), sole-proprietors, partnerships, non-profit and charitable organizations are eligible for a DUNS Number.


Assignment of a DUNS number is absolutely FREE for all entities required to register with the federal government by a regulatory agency. This includes federal contractors and prospective government vendors.
