If your wallet is stolen, the following steps are to be taken
1. We have been told we should cancel our credit cards immediately. The key is having the toll free numbers and your card numbers handy so you know whom to call. Keep those where you can find them.
2. File a police report immediately in the jurisdiction where your credit cards, etc., were stolen. This proves to credit providers you were diligent, and this is a first step toward an investigation (if there ever is one). However, here is what is perhaps most important of all (I never even thought to do this.)
3. Call the three national credit reporting organizations immediately to place a fraud alert on your name and Social Security number. I had never heard of doing that until advised by a bank that called to tell me an application for credit was made over the Internet in my name. The alert means any company that checks your credit knows your information was stolen, and they have to contact you by phone to authorize new credit. By the time I was advised to do this, almost two weeks after the theft, all the damage had been done. There are records of all the credit checks initiated by the thieves' purchases, none of which I knew about before placing the alert. Since then, no additional damage has been done, and the thieves threw my wallet away this weekend (someone turned it in). It seems to have stopped them dead in their tracks.
