D-U-N-S Number
A D-U-N-S Number is a unique 9-digit identifier issued by Dun & Bradstreet that identifies your US business separately from you personally. It is essential for establishing business credit and accessing trade credit lines.
What Is a D-U-N-S Number?
A D-U-N-S Number (Data Universal Numbering System) is a free, unique 9-digit business identifier issued by Dun & Bradstreet, a US credit reporting and business information company. Unlike an EIN, which is a tax ID, the D-U-N-S Number exists purely to build your business credit profile and reputation within the US market.
Once you have a US LLC and EIN, applying for a D-U-N-S Number takes about 15 minutes online and costs nothing. Dun & Bradstreet will verify your LLC information against public records and issue the number immediately or within a few business days.
Why Non-US Founders Need It
Your personal credit history does not follow you to the US. A D-U-N-S Number creates a separate, clean business credit file that vendors, suppliers, and lenders can review. This becomes your foundation for:
- Opening trade credit accounts with vendors (net-30, net-60 terms)
- Applying for business credit cards without a personal guarantee
- Qualifying for wholesale or bulk supplier discounts
- Demonstrating financial credibility to landlords or partners
How It Fits Your Setup Journey
The typical timeline for a non-US founder looks like this:
- Form a US LLC (usually Wyoming for privacy and cost)
- Get an EIN from the IRS (for tax purposes)
- Open a US business bank account (Mercury, Wise, or Relay work fully remote)
- Apply for a D-U-N-S Number (immediate, free)
- Wait 60-90 days for business credit history to build
- Apply for business credit cards or trade credit
The D-U-N-S Number is not mandatory to run your US LLC, but it is the fastest way to separate your personal and business finances in the eyes of US creditors. Many founders skip it early and regret it later when they need a business loan or supplier terms.
How to Apply

Common Misconceptions
It is not an SSN. Your D-U-N-S Number is tied to your business entity, not your personal identity.
It is not the same as your EIN. Your EIN is a tax ID; your D-U-N-S Number is a credit ID. You need both.
It does not cost money. Dun & Bradstreet makes money from lenders and vendors who pull your D-U-N-S credit report, not from you.
It is not mandatory. But if you want to build business credit fast, it is the single most important first step after opening your US bank account.
Frequently asked questions
Can I apply for a D-U-N-S Number before I have a US LLC?
No. Dun & Bradstreet will verify your LLC against public business records. You must form your LLC first, obtain your EIN, and wait for those records to appear in the system (usually 1-2 weeks). Then apply for the D-U-N-S Number.
How long does it take to get a D-U-N-S Number?
Most applications are approved instantly online, but Dun & Bradstreet may take up to a few business days to verify your information. Once issued, the number is active immediately.
Will a D-U-N-S Number affect my personal credit?
No. Your D-U-N-S Number and business credit are completely separate from your personal credit report and score. They exist in different systems.
Do I need a D-U-N-S Number to open a US business bank account?
No. Most online banks (Mercury, Wise, Relay) only need your EIN and LLC documents. However, a D-U-N-S Number helps later when you apply for business credit cards or trade credit.
Can I get a D-U-N-S Number if I am not a US citizen?
Yes. The D-U-N-S Number is issued to your business entity (the LLC), not to you personally. Non-US founders get D-U-N-S Numbers all the time, especially once they have a valid US LLC and EIN.
