Equifax and Experian both automatically pull new business records from the Secretary of State. As soon as you form an LLC or incorporate, you'll be recognized.
Dun & Bradstreet is the most commonly used business credit bureau and has its own system. The bureau creates three separate credit scores for your company based on public records, industry information, and more.
To view your DB credit reports and make it easier in the future for lenders and suppliers to issue you credit, you'll need a data universal numbering system (DUNS) number. If you've done business with suppliers already, you may even already have one.
Before you apply, check for a DUNS number by entering your company name. If you don't find a number, you can file with D&B to get one. But before you can access it, you'll need at least three trade references. Ask companies or suppliers you've done business with to report your payment history to D&B -- it's free.
