CU Dude,

To start, shred or store securely your credit card statements, purchase receipts and anything else that has your account number printed. I would consider subscribing to a credit monitoring service as well.

I think the best way to protect your credit is only available in California for a limited time, depends on what gets passed in federal legislation.  There is pending legislation to get rid of the states laws so it makes it easier on credit bureaus.

California residents can do a credit freeze, which basically restricts credit report access from anyone unless you give them explicit permission to do so. You need to do this individually at all three credit bureau companies.  Check www.bankrate.com search for Amy C. Fleitas article on "credit freeze".

Costs $$ if you are not an identity theft victim but well worth it. No one but you can change the address on the credit bureau records. You will also have a PIN to change any personal info with the credit bureau.  Next time someone applies for credit in your name it will show up blank and "frozen" and the imposter will be busted!
