How to get a DUNS number for free in 2026

A DUNS number is a 9-digit identifier issued by Dun & Bradstreet (D&B) — the largest business credit bureau. Every business credit report starts with a DUNS. If you want vendors to report your Net-30 payments (which is how your Paydex score gets built), you need one.

D&B offers DUNS numbers for freeif you're willing to wait ~30 days, or for ~$200 via their expedited service for 5-7 business days.

What is a DUNS number, exactly?

Dun & Bradstreet has been maintaining business identifiers since 1963. Every business in their database gets a 9-digit DUNS number that stays with the entity for its lifetime. Vendors, banks, and lenders use it as the primary key for pulling your business credit report.

A DUNS on its own doesn't mean anything about your credit — it's just an ID. The credit history that gets attached to it (via reporting vendors, credit references, and public records) is what generates your Paydex score.

Do you need one?

Yes, if you plan to build business credit. Specifically:

• Every D&B-reporting Net-30 vendor requires a DUNS (or requests one on your behalf if you don't have one).
• Most business credit cards check your D&B file — no DUNS = no D&B file = automatic downgrade of your application.
• Government contracts require a DUNS or its successor (UEI) for you to bid.
• Corporate customers over $1M in revenue often refuse to onboard you without one.

How to request a DUNS (free)

1. 1Confirm you don't already have one using the D&B lookup tool linked above. Requesting a duplicate delays your file.
2. 2Get your EIN first. D&B verifies your EIN against IRS records — no EIN = automatic rejection. See How to get an EIN in 2026.
3. 3Visit the D&B free DUNS page at dnb.com/duns/get-a-duns. Click "Request a D-U-N-S Number."
4. 4Fill out the request form with your legal business name, EIN, physical address, phone number, and business type. Every field must match your public records (state filings, IRS).
5. 5Answer the D&B phone verification call.Within 5-15 business days, D&B calls the business phone number you submitted. They'll ask a few questions about your business to verify it exists.
6. 6Wait for your DUNS notification.D&B emails you the DUNS number within 30 business days total. Save the email — that's your proof.

The paid expedited option

D&B Direct+ is D&B's paid tier. Costs vary, but expect ~$200 for expedited DUNS assignment. Turnaround drops from 30 days to 5-7 business days.

Only worth it ifyou have a vendor or lender waiting on you and can't afford the delay. Otherwise the free option builds a stronger organic file — D&B tends to give expedited requests slightly less "natural" treatment for the first year of history.

Why free DUNS requests fail

DUNS vs UEI (for government work)

In April 2022, the US federal government stopped using DUNS as the primary identifier for federal contracting. It was replaced with the UEI (Unique Entity Identifier), which is issued for free via sam.gov.

You still need a DUNS for private-sector business credit.The UEI only applies if you're bidding on federal contracts. For everything else — Uline, Home Depot, Chase Business Complete, Amex — D&B's DUNS remains the key.

What to do after you get your DUNS

1. 1Verify your D&B profile.Log into iUpdate (D&B's free profile tool) and confirm your business info is correct. Errors here become vendor rejections later.
2. 2Apply to Uline immediately.Uline is one of the fastest D&B reporters — within 60 days of your first paid Net-30 invoice, you'll have your first trade line.
3. 3Apply to Quill or Grainger next.D&B doesn't publish a Paydex score until you have 3+ trade lines. Stack them fast.
4. 4Monitor your file monthly. Free at nav.com or via D&B directly. Errors on your file (wrong address, wrong industry code) tank scores.
