What credit bureau does the Delta Reserve Business card use for approval?
The Delta Reserve Business Card uses either a business credit bureau or a consumer reporting agency for approval. It really depends on the information the applicant provides to the issuer.
When they use a business credit bureau, it will usually be either Equifax or Experian. The Delta Reserve Business Card seldom uses Dun & Bradstreet for approval.
If they decide to use a consumer reporting agency, then American Express may use any of the three major - Equifax, TransUnion or Experian.
Lastly, if you already have a credit card with American Express, there is a small chance that they won't use a credit bureau at all to reach a decision for your Delta Reserve Business Card application.
