Business Credit
What is a D-U-N-Sยฎ Number and How Do I Get One?
โœ“ Free to obtain Issued by Dun & Bradstreet 9-digit identifier Required for federal contracts
A D-U-N-Sยฎ Number (Data Universal Numbering System) is a unique 9-digit identifier assigned to your business by Dun & Bradstreet (D&B). Think of it as a Social Security number for your business โ€” it anchors your business credit profile and is required for federal contracts, SBA loans, and many vendor applications.
A DUNS number unlocks critical business infrastructure. Without one, you may be invisible to lenders, suppliers, and government agencies that rely on D&B's database to verify business legitimacy.
  • Federal contracts & grants โ€” Required by SAM.gov to bid on U.S. government contracts
  • Business credit building โ€” D&B's Paydex score (0โ€“100) is built on your DUNS record
  • Vendor applications โ€” Many wholesalers and suppliers verify DUNS before extending net terms
  • SBA loans โ€” Lenders reference D&B data during underwriting
  • Corporate partnerships โ€” Large corporations may require it before doing B2B business with you
Getting a DUNS number is free and straightforward through D&B's official portal.
  1. Go to dnb.com/duns-number/get-a-duns.html โ€” use only the official D&B site to avoid third-party fees
  2. Click "Get a D-U-N-S Number" and select your country (United States)
  3. Search for your business to see if a record already exists
  4. If none exists, complete the registration form with your legal business name, address, EIN, and contact info
  5. Standard processing takes up to 30 business days (free). Expedited processing (1โ€“5 days) is available for a fee
  6. Your DUNS number will be emailed to you once assigned
Pro Tip: Once you have your DUNS, start paying vendors and suppliers on time โ€” every on-time payment is reported to D&B and builds your Paydex score, which ranges from 0 to 100. A score of 80+ is considered excellent.
These are two completely different identifiers that serve different purposes โ€” and your business needs both.
  • EIN (Employer Identification Number) โ€” Issued by the IRS. Used for federal tax filings, opening bank accounts, and hiring employees
  • DUNS Number โ€” Issued by Dun & Bradstreet (a private company). Used to build business credit, apply for government contracts, and establish vendor credibility
  • Your EIN is required before applying for a DUNS number
  • Neither replaces the other โ€” think of the EIN as your tax ID and DUNS as your credit ID
Tax ID / IRS
How Do I Get an EIN โ€” and Is It Really Free?
โœ“ 100% Free from IRS Issued instantly online Required for LLCs & Corps Needed to open business bank account
An EIN (Employer Identification Number), also called a Federal Tax Identification Number, is a free 9-digit number issued by the IRS. It's the business equivalent of a Social Security number and is required to open a business bank account, hire employees, file taxes as an entity, and apply for business credit.
You are required to have an EIN if any of the following apply:
  • You operate as an LLC, S-Corp, C-Corp, Partnership, or Nonprofit
  • You have or plan to hire employees
  • You file excise tax returns (alcohol, tobacco, firearms, etc.)
  • You withhold taxes on income paid to a non-resident alien
  • You have a Keogh plan or certain retirement accounts
Sole Proprietors: You can use your Social Security number instead, but many experts recommend getting an EIN anyway to separate personal and business identity, reduce identity theft risk, and build a business credit profile.
The IRS provides EINs free of charge. Never pay a third party for an EIN โ€” it is always free directly from the IRS.
  1. Go to irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online
  2. Click "Apply Online Now" โ€” the online system is available Monโ€“Fri, 7 a.m. to 10 p.m. ET
  3. Select your entity type (LLC, Corporation, Sole Proprietor, Partnership, etc.)
  4. Answer questions about your business purpose, state of formation, and responsible party
  5. The IRS validates your information and issues your EIN immediately upon completion
  6. Download and save your EIN confirmation letter (CP 575) โ€” you'll need it often
Alternative methods: You can also apply by fax (Form SS-4, ~4 business days), mail (~4 weeks), or phone for international applicants. Online is the fastest and recommended method.
Your EIN is foundational โ€” nearly every significant business action requires it.
  • Open a business bank account โ€” required by virtually all banks and credit unions
  • Apply for business credit cards โ€” build credit without using your personal SSN
  • Hire employees โ€” required for payroll tax withholding and W-2 filings
  • File business taxes โ€” LLCs, Corps, and Partnerships file under the EIN
  • Apply for business licenses โ€” many states require it for licensing
  • Apply for a DUNS number โ€” D&B requests your EIN during registration
  • Apply for SBA loans or grants โ€” lenders use EIN to pull business financial records
