To register your business with the credit bureaus, form a legal entity, get an Employer Identification Number, and then create or claim a profile with each of the three major commercial bureaus: Dun & Bradstreet, Experian Business, and Equifax Business. Each bureau builds your file differently, and none of them will know your company exists just because you filed paperwork with the state. Registration is only the start. A usable score typically takes six to twelve months of active, on-time payment history to appear.
Set Up the Entity and Tax ID First
Before any bureau will track your company, it has to exist as a separate legal entity. That means filing articles of organization for an LLC, or articles of incorporation for a corporation, with your state’s Secretary of State. In most cases the total cost to register is less than $300, though fees vary by state and structure.1U.S. Small Business Administration. Register Your Business Sole proprietors can build business credit too, but a separate entity creates a cleaner legal wall between your personal finances and the company’s obligations.2Experian.

Once the entity is formed, apply for an Employer Identification Number from the IRS. This nine-digit number is your company’s federal tax ID, and every bureau and lender will ask for it.3Office of the Law Revision Counsel. 26 USC 6109 – Identifying Numbers The IRS issues EINs for free through its online application and delivers the number immediately. The whole process takes about 15 minutes.4Internal Revenue Service. Get an Employer Identification Number Third-party websites that charge for this are unnecessary, and the IRS warns against them.
Then make your business name, address, and phone number consistent everywhere. Bureaus pull from public records, state filings, and directory listings to verify that a company is real. A dedicated business phone number listed in the 411 directory adds a layer of legitimacy that D&B in particular looks for during verification. A residential address or P.O. Box can slow things down or prevent a profile from being created, so a commercial address that matches your state filing is worth the effort.
Get a DUNS Number from Dun & Bradstreet
Dun & Bradstreet assigns every registered company a Data Universal Numbering System (DUNS) identifier, a unique nine-digit number that anchors your D&B credit file. You apply through D&B’s website by entering your legal business name, headquarters address, and other entity details.5Dun & Bradstreet.

The standard application is free and takes up to 30 business days.5Dun & Bradstreet.

Create or Claim Your Experian Business File
Experian doesn’t require a separate application the way D&B does. Start by searching for your business on their commercial credit portal using your company name or tax ID.7Experian. Welcome to Experian Business Credit If your company already appears in public records, Experian may have created a file automatically. If no profile exists, you can submit a request to establish one through their site.2Experian. How to Establish Business Credit
Viewing your report costs money once it exists. A single CreditScore report runs $59.95, and the more detailed ProfilePlus report is $69.95. Experian also offers an annual monitoring subscription called Business Credit Advantage for $199 per year.8Experian. Business Credit Report – Run a Free Company Search
Get Reported to Equifax Business
Equifax builds business credit files differently. It relies heavily on the Small Business Financial Exchange (SBFE), a data-sharing consortium of more than 140 U.S. small business lenders, including the largest business credit card issuers and commercial banks.9Small Business Financial Exchange. SBFE These member institutions report their customers’ payment data to the SBFE, and Equifax uses that data to build and update credit profiles.10Equifax. Small Businesses Benefit from Renewed Equifax-SBFE Partnership
The practical implication is that you can’t walk up to Equifax and request a profile the way you can with D&B or Experian. Your file gets created when a member lender reports data about your business. Opening a business credit card, line of credit, or loan with an SBFE member is the most reliable route to an Equifax profile. You can check whether a file already exists through Equifax’s small business self-service portal.
Build Tradelines So the Profiles Have Data
A credit profile with no payment history is like an empty resume. To populate it, you need tradelines: credit accounts with vendors that report your payment activity to the bureaus. Not every vendor reports, so be deliberate. Office supply companies, industrial suppliers, and shipping vendors are common starting points, but confirm that a vendor reports to the specific bureau you’re targeting before opening an account.
Most reporting vendors offer net-30 payment terms, meaning you receive goods or services and pay the invoice within 30 days. When you apply, the vendor will ask for your EIN and DUNS number to link the account to your commercial credit profile rather than your personal one. After you pay the invoice, the vendor transmits data about the transaction, including your credit limit and whether you paid on time, to the relevant bureaus.
Start with two or three reporting accounts and pay every invoice on time or early. Consistency matters far more than the dollar amount of each purchase. Most businesses can generate a usable credit score within six to twelve months if they maintain several active tradelines with clean payment records.
Monitor Your Reports and Dispute Errors
Business credit reports can contain errors just like personal ones, and those errors can cost you favorable terms or kill a deal. One important boundary: business credit reports don’t come with the same legal protections as personal ones. Under the Fair Credit Reporting Act, a “consumer” is defined as an individual, and a “consumer report” covers information used for personal, family, or household purposes.11Office of the Law Revision Counsel. 15 USC 1681a – Definitions; Rules of Construction Business-purpose credit reports fall outside that definition, so the bureaus aren’t legally required to investigate disputes within 30 days or follow the other procedures that protect consumers. They may still offer dispute processes voluntarily, but you don’t have the same statutory leverage.
Experian does provide a dispute mechanism. You can use the “Submit Data Dispute” button at the bottom of your report or email your dispute to their business disputes team. Investigations are generally completed within 30 days, though complex cases take longer. If Experian makes corrections, you’ll receive an updated report for free.12Experian.

View / Update Company Information
Check your reports at least quarterly once tradelines are active. Watch for payments misattributed to the wrong company (common with similar business names), outdated information from vendors who stopped reporting, and UCC filings that should have been terminated but still appear active. Catching these early is much easier than unwinding damage after a lender has already declined you.
What Registration Doesn’t Do
Registering with the bureaus and building a strong business file is useful, but it doesn’t eliminate your personal financial exposure the way many guides imply. Most lenders still require a personal guarantee from the business owner, especially for newer companies.13U.S. Small Business Administration. Unsecured Business Funding for Small Business Owners Explained A personal guarantee means that if the business can’t pay, you’re personally on the hook regardless of your business credit score. Some alternative lenders waive the personal guarantee for established businesses with sufficient revenue history, but that’s the exception for companies just starting out. Business credit registration lays the foundation; the value compounds over months and years of consistent, on-time activity on top of it.
