The direct dispute implementing rules recommend that the consumer attach a copy of the relevant portion of a recent credit report that shows how the account is listed as a means of identification of the disputed information, and showing that the disputed information has actually been reported.
That should be more than adequate to enablet them to idenfify your account. If they find it lacking, they are required, if file a direct dispute, to respond within the dispute period, and inform you of what is needed should they be unable to investigate your dispute.
Go ahead and file the direct dispute, which will trigger their requiremnt to either investigate or notify you of what is considered lacking.
