A Duns Number is an identification number created and assigned by Dun & Bradstreet (D&B) to business entities. It is a nine-digit number that acts as a unique identifier for each business in its database. The number is used to help businesses track, compare, and differentiate themselves from one another in the business world. Obtaining a Duns Number is an important step for any company looking to build credibility among customers, suppliers, lenders, and potential partners — as it proves their legitimacy and helps them stand out from their competition. It’s also necessary for companies who wish to register with D&B, so they can receive access to their database of credit information. All in all, getting a Duns Number goes a long way in improving a business’s reputation and increasing the chances of success!
