What is D-U-N-S Number?

A D-U-N-S number is a unique nine-digit identification number assigned to a business entity by Dun & Bradstreet (D&B), a business information company. The acronym D-U-N-S stands for “Data Universal Numbering System (DUNS).”

The D-U-N-S number is used as a standard business identifier and is recognized worldwide. It is often required by businesses when applying for credit, government contracts, or other business transactions.

The D-U-N-S number is assigned based on information provided by the business entity, such as its legal name, address, and other business details. D&B uses this information to create a business credit report, which includes the D-U-N-S number, as well as other information such as credit history, payment behavior, and financial stability.

Having a D-U-N-S number can provide a business with a level of credibility and can help establish a business credit profile. It also allows other businesses to verify the identity and legitimacy of the business entity, making it easier to establish business relationships and engage in transactions.

Please note that “Businesses no longer have to go to a third-party website to obtain their identifier (DUNS number). This transition allows the government to streamline the entity identification and validation process, making it easier and less burdensome to do business with the federal government.” For more information, check the “Basic Requirements” in the Contracting Guide on SBA website.
