What is a DUNS number and do I need one for business loans?

A DUNS (Data Universal Numbering System) number is a unique 9-digit identifier assigned by Dun & Bradstreet to track your business credit file. It's required to apply for SBA loans, government contracts, and to build a PAYDEX score. Getting a DUNS number is free at the D&B website and takes 30 days for standard registration or 24-48 hours for expedited. Apply before you need financing.
