A friend's ID was used to open a number of business credit cards fraudulently. Since not all companies report business credit lines on personal credit reports, how can my friend find other open cards before the companies/collectors call for payment of the unpaid balances? (A list of phone numbers, etc...) He would like to shut this guy down and insure future problems will not pop up. Police report has been filed and freeze put on three credit bureaus for personal credit... Thanks for any help/suggestions...

I would call each bank that put an INQ on my report. I would also call CITI because they have some
*no personal guaranteed cards* that do not require a credit check.

Check for a DUNS# at DnB.com and smartbusinessreports.com (experian business report). The business might not be listed yet, but you can notify them of the fraud and they will mark the file.

Frozen personal reports and flagged biz reports WILL shut him down, but the mess will still be there.
