How to Get a D-U-N-S Number for a Non-Resident LLC

If you are running a US LLC from Europe, a D-U-N-S number is the quiet piece of infrastructure that unlocks business credit, vendor accounts, and government marketplaces. Here is what it is and how to get one for free.

What a D-U-N-S number actually is

A D-U-N-S number (Data Universal Numbering System) is a nine digit identifier issued by Dun and Bradstreet, a commercial data company that has been tracking businesses since the 1800s. Think of it as a passport number for your company inside D&B's database. It does not expire, it is unique to your business, and it is used by lenders, vendors, government agencies, and large platforms to look up a company and see whether it exists, how long it has been operating, and eventually what its credit profile looks like.

Getting a D-U-N-S number does not itself give your LLC a credit score. It simply creates the file that a credit history can later attach to. No file, no history, no score.

Why it matters for a non-resident LLC

Most European founders run into D-U-N-S in one of three situations.

• You want to open net-30 vendor accounts (office supplies, software, shipping) that report payment history to build business credit separate from your personal name.
• You are applying to a platform that requires one outright, such as the Apple Developer Enterprise Program or a government contracting portal like SAM.gov in the US.
• You want your LLC to eventually qualify for business credit cards or lending that looks at the company itself rather than your personal credit history, which as a non-resident you likely do not have in the US anyway.

Because a foreign-owned LLC has no personal US credit history behind it, the D-U-N-S number and the business credit file it enables become one of the few ways to prove creditworthiness at the company level over time.

What you need before you apply

D&B wants your business to look real, findable, and consistent with public records. Have these ready before you start the application:

• Your LLC's legal name exactly as filed with the state, no abbreviations or variations.
• A US physical street address, not a bare PO box. A registered agent address or a proper virtual mailbox with a suite number usually works.
• A working phone number reachable during US business hours. D&B sometimes places a verification call, so a US virtual number that forwards to you is worth setting up.
• Your EIN (Employer Identification Number) from the IRS. You do not need an SSN or ITIN to get an EIN. As a non-resident with no US Social Security Number, you apply for the EIN by fax or mail, or by phone through the IRS international line, using Form SS-4. The standard online EIN application is not available to you without an existing SSN, ITIN, or EIN as responsible party.
• A general description of what your business does and an industry classification code.

How to get your D-U-N-S number for free

D&B will happily sell you an 'expedited' or 'premium' registration, but a standard D-U-N-S number is free and that is the version most founders need.

1. Go to D&B's own D-U-N-S number request page (search 'D&B get a D-U-N-S number' rather than a third party reseller) and choose the free option rather than any paid credit monitoring bundle.
2. Enter your LLC's legal name, US address, phone number, EIN, and a short business description. Everything should match your state formation documents and IRS records exactly, since mismatches are the most common cause of delay.
3. Submit the request. D&B may reach out by phone or email to confirm the business is genuine, particularly for newly formed companies with a thin public footprint.
4. Once verified, D&B issues the number and creates your business file, which you can view (and later manage) through their business portal.

How long it takes and what can go wrong

The free route typically takes a couple of weeks, sometimes longer if D&B cannot immediately verify the business. Paid expedited options exist and can shorten this to a few days, but they are optional. Common snags for non-resident founders include using a PO box that D&B flags as undeliverable, a business name that does not exactly match the state filing, or a phone number that never gets answered when D&B calls to verify.

A practical fix is to make sure your registered address and phone number are stable and monitored before you apply, and to apply for the EIN first so it is issued and matches everything else in the application.

Using your D-U-N-S number to build business credit

The number itself does nothing until activity gets reported against it. Once you have it, the usual next steps are opening a few net-30 vendor accounts that report to D&B, paying them on time, and gradually applying for business credit cards or lending that pull a D&B report instead of a personal credit check. This is a slow, deliberate process measured in months, not days, and it runs in parallel with the more immediate priorities of getting your LLC properly set up: EIN, US business bank account, and business cards that work without a US credit history.

This is also where the paperwork side of a non-resident LLC tends to bite people. A foreign-owned single-member LLC has to file Form 5472 alongside a pro-forma Form 1120 every year, even if the company had no income and did nothing. It is an information return, not a tax calculation, but skipping it carries a penalty of twenty-five thousand dollars per missed filing. Founders Credit handles LLC formation, EIN applications, ITIN if you need one, US business banking, and business cards for non-resident founders end to end, and can point you to the right D-U-N-S setup as part of getting the whole structure built correctly the first time.
