What should I do if I suspect a caller is an identity thief?

Whenever anybody calls you where you suspect that they may be trying to extract private data or they're an identity thief, the best thing to do first is to do a caller id or star 69 to find out the phone number that they're calling from, and then immediately report that information to law enforcement. Also, call the phone company right away because generally they have information on their databases that has that phone number if it didn't show up on caller id, or it didn't show up on star 69.
