What Is a DUNS Number?

What Is a D‑U‑N‑S Number

A D‑U‑N‑S Number is a unique nine-digit identification number assigned by Dun & Bradstreet (D&B) to businesses worldwide.

D&B is a global business information and analytics provider, offering commercial credit scores and ratings, credit monitoring, and other business insights.

A D‑U‑N‑S Number is assigned to each physical location of a business, allowing D&B to create a business credit file and track the business’s performance.

DUNS is a short way of saying “Data Universal Numbering System.” It was made by D&B in 1962 to help them keep track of credit.

Nowadays, D&B says that the D-U-N-S Number is what most businesses use to be identified all over the world.

Besides the nine-digit number, a D-U-N-S Number also tells you other important stuff about the business, like its name, where it’s based, and what kind of business it is.

Why Do I Need a D‑U‑N‑S Number?

Why Do I Need a D‑U‑N‑S Number

A D‑U‑N‑S Number can be valuable for businesses in several ways, including:

Establish credibility with lenders, and expedite applications for loans and contracts

If a business wants a loan or a contract, the lender or buyer might check their business credit report to see if they can be trusted to pay back what they owe. D&B is one of the biggest companies that make these reports.

Having a D-U-N-S Number can show that the business is real, and it makes it easier for lenders and buyers to see the credit report.

In addition, some lenders or government agencies may require a D‑U‑N‑S Number as part of their application process.

Do business with the government and companies outside the United States

Many government agencies and international companies use the D‑U‑N‑S Number to identify and track businesses.

For example, the US government requires all businesses that want to bid on federal contracts to have a D‑U‑N‑S Number.

Similarly, some foreign countries may require a D‑U‑N‑S Number as part of their import/export regulations.

Make sure other businesses get a complete and accurate story about your business

Because D&B uses the D‑U‑N‑S Number to track a business’s credit history, having a D‑U‑N‑S Number can help ensure that other businesses get a complete and accurate picture of your business’s creditworthiness.

This can be important when seeking new business partners, suppliers, or customers.

Is a DUNS Number the Same as a Federal Tax ID Number?

Is a DUNS Number the Same as a Federal Tax ID Number

No, a D‑U‑N‑S Number is not the same as a Federal Tax ID Number (also known as an Employer Identification Number or EIN).

A Federal Tax ID Number is a nine-digit number the Internal Revenue Service (IRS) assigns to identify businesses for tax purposes.

In contrast, a D‑U‑N‑S Number is assigned by D&B and is used to track a business’s credit history and performance.

How Do I Look Up My DUNS Number?

You can look it up using the D&B website if you already have a D-U-N-S Number. Simply go to the D&B search page and enter your business name and location.

D&B will then display your D‑U‑N‑S Number (if you have one) and other information about your business.
