How a credential is verified

A Verified badge is checked against evidence before it exists: BDC’s own published coverage, or a purchase order, appointment letter or written confirmation from the client or main contractor. The credential number ties the badge to the project’s record, so a bid assessor can check the firm, role and year in one click. Claims that can’t be evidenced are declined.
