I'm guessing that you work for the Federal government. As these those are the guys who compromised by identity (twice) and give me CSID monitoring.
Since someone has tried to get a cc in your name, you're going to have to give CSID a PoA unless you want to take the steps yourself. Credit agencies aren't going to work with CSID on your behalf unless they have a PoA. Yes, if I get in that situation it would make me a bit uncomfortable, however, I'd end up doing it.
