What Is It?

If the D&B brand name is new to you, you’re probably wondering, what the heck is a DUNS Number anyway?

DUNS numbers are unique, nine-digit business identifiers that are associated with a single business entity and linked to their credit profile. Since 1963, Dun & Bradstreet has been issuing them, and recording data about tradeline and credit activity that is reported to them from issuers of credit.

D&B Ratings

Their ratings range from A through F, with A being the best and F being the worst. If your credit is in good standing, you’ll get an A rating and this alone can greatly help you get a business loan approved.

Faster Loan Approval

When you plan to get a loan for your business, remember that any creditor wouldn’t just hand you money right away. They will conduct a thorough review of your company’s financial standing. Once determined that you’re business reputation is good, only then can the loan be approved.

In connection, a DUNS number expedites the process of the review of your company’s financial standing. Also, it provides more credibility so that creditors will be more convinced to lend money. Remember that with a DUNS number you have better chances to get an ideal business loan or line of credit with extended terms and low APR interest rates.

Easier Transactions

No matter how well your business thrives, without a DUNS number, your tradeline transactions will be limited to paying upfront for everything you buy. If you want to be billed on a Net 30, Net 60, or Net 90 invoice, you’ll wish you had a DUNS Number. 

Delayed payments will allow you get to receive what you need while giving you time to find the money to pay for them. The more diligent you are in paying your bills on time, the higher your Dun & Bradstreet credit rating will be, and the more tradelines that will open up for you.

In essence, the better your rating, the more credible or trustworthy you’ll seem to anyone who wants to do business with you.

Business Credit Understanding

With a DUNS number, you also get to understand your business’s credit better, as you’ll be able to view all record credit and tradeline information related to your business.
