How to Get a D-U-N-S Number for Your Business

A D-U-N-S number is free through Dun & Bradstreet, with standard processing taking up to 30 business days. Paid expedited options are available if you're on a tighter timeline. Here's when the number matters, how to apply without delays, and what to do once you have it.

When a D-U-N-S number matters

A D-U-N-S (Data Universal Numbering System) number is a unique nine-digit identifier assigned by Dun & Bradstreet that acts as a permanent business identity across commercial databases. Most teams only encounter D-U-N-S requirements during platform enrollment or when business credit starts to matter. Apple requires one for the Apple Developer Program, the FDA requires one for food-related facilities, and many retailers still use it for supplier onboarding and grants.

Even without a hard requirement, we treat a D-U-N-S number as the identifier that connects your business to its D&B file and, eventually, a PAYDEX score. That file is what vendors and lenders check when deciding whether to extend credit terms. For a growing company negotiating net-30 with a new supplier, a verified D&B profile reduces the odds of being pushed to prepayment, which matters if you're exploring EIN-only corporate cards or other financing that relies on business fundamentals.

How to check and apply

Most delays happen when details don't match official records or when a duplicate D&B profile already exists. Before submitting a new request, search your business name and address using D&B's D-U-N-S Lookup. Many businesses already have numbers because D&B creates profiles from supplier onboarding and certain marketplaces. If you find a close match, claiming or correcting that profile is typically faster than starting fresh.

When you're ready to apply, you'll need the following:

• Legal business name matching your state registration exactly
• Physical address (not a PO box), EIN, and phone number
• Entity type, year established, and employee count

Submit through dnb.com or by phone at 1-866-705-5711, and avoid third-party sites that charge for what's otherwise a free request. Enter every detail exactly as it appears on official documents, since mismatches with state or IRS records are the most common cause of delays. If you're also setting up business credit without a personal credit check, having your D-U-N-S number ready speeds up the process.

What to do after you get it

The number itself is just the starting point. Review your record in D&B's free Profile Manager and confirm that vendors are actually reporting payment activity. If you aren't seeing data, the issue is usually non-reporting vendors rather than an application mistake. Once your D&B profile shows consistent payment history, it strengthens your position when applying for business credit cards that evaluate company financials instead of personal credit.

Platforms like Ramp already assess businesses based on cash flow and bank balances rather than personal credit scores. A strong D&B profile adds credibility when you're working with vendors who still rely on traditional credit checks, and it complements the no-personal-guarantee cards that growing companies increasingly prefer.

Frequently asked questions about how to get a D-U-N-S number for your business

How long does it take to get a D-U-N-S number?

Standard processing takes up to 30 business days. Paid expedited options through D&B return the same number faster if you're working against a deadline.

Is a D-U-N-S number free?

Yes. You can request one at no cost through dnb.com. You only pay for expedited processing or premium monitoring.

Do I need a D-U-N-S number for federal contracts?

No. Federal registrations now use a Unique Entity Identifier (UEI) through SAM.gov, which replaced the D-U-N-S requirement in 2022.

Can a D-U-N-S number help me get approved for a business credit card?

Not directly. Most corporate card providers evaluate cash flow and bank balances rather than D&B scores. But a strong D&B file helps with vendor negotiations and traditional lending where business credit history still matters.
