I opened my email yesterday to an email with the following subject:
LifeLock Identity Alert(tm) [Reference:XXXXXX-XXXXXX]
My heart skipped a beat. I opened it up, and the message inside told me that someone had applied for credit with a certain card company. If that person was not me, I should call LifeLock and talk to their rep. So, I called. After walking through their menu system, I finally got a human and she asked me all kinds of questions to make sure I was who I said I was. Here is a tip: REMEMBER the answers to your security questions!
We talked for a bit, and then the light came on. I had, in fact, filled out an application as part of a points-earning program that I take part in. I felt like an idiot, except that I had done that some time ago. Turns out, the card company was just slow in reporting that out. In effect, it could have been a week or so between the time someone had tried it and I got notified. Luckily, everything was legit this time.
I'm very glad I have the LifeLock service. I know the things they do are things I could do on my own if I had the time and memory. I don't. I feel a whole lot better knowing those guys are out there watching for me.
