PLEASE NOTE: This is the current D&B statement regarding Covid-19 and the status of trade reference submissions

Dun & Bradstreet continues to monitor the impact of COVID-19.

Unlike consumer credit, corporate credit bureaus give you the option of adding payment history to your file using one of their paid services.
