DUNS Number: What Is A DUNS Number & What Is It Used For?

A D-U-N-S Number (also abbreviated as “DUNS”) is a unique nine-digit identification number assigned by Dun & Bradstreet (D&B) to a business or organization. It’s used to identify and track companies and their creditworthiness, and is often required for business-to-business transactions, government contracts, and other financial transactions. A common requirement for many online businesses is to register for a DUNS number in order to sign up for the Apple and Google Play Developer Programs or to apply for government grants.

Does a small business need a DUNS number?

It is not legally required for a small business to have a DUNS number, but having a one can make it easier for a small business to obtain business loans and access other services offered by D&B. Additionally, many government agencies and suppliers require a DUNS number as part of their vendor registration process, so having a DUNS number can open up new opportunities for a small business to work with government agencies and suppliers.

Applying for a DUNS Number

A company can obtain a DUNS number by registering with D&B on their website and complete the registration process. The registration process typically requires you to provide basic information about your business, such as its legal name, address, and your contact information, as well as information about the company ownership, structure, and operations.

If you have an online business or Shopify e-commerce store, make sure you include the URL of your business during the sign up process – your DUNS listing will be public, and it’s a great way to drive traffic to your business by including a link to your website!

Once the registration is complete, D&B will assign a DUNS number to the company, which can then be used to obtain business credit and access other services offered by D&B.

A DUNS Number and an Employer Identification Number (EIN) are both unique identification numbers assigned to businesses, but they serve different purposes. A DUNS number is used to establish the creditworthiness of a business and track its payment history, financial stability, and other factors that can affect its creditworthiness.

An EIN, on the other hand, is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to businesses for tax purposes. It is also known as a Federal Tax Identification Number, and it is used to identify a business for tax-related matters such as filing taxes, opening bank accounts and applying for business licenses. Nearly every business or LLC with more than one owner (or member) will be required to apply and obtain an EIN number from the IRS.
