* CreditSignal only indicates that your D&B scores and ratings have changed and alerts you when your business credit file has been purchased. To view actual scores and ratings and learn about what industries are purchasing your D&B file, we recommend that you upgrade to one of our business credit monitoring or credit building solutions. Please note, due to the proprietary nature of these inquiries and inquiry requests, only the industries in which the purchasing customers reside will be revealed.
