This is exactly why you need to put a freeze on all three of your credit reports. In Florida this is free for seniors and no one can steal your identity or open a false account in your name. It is cheaper and more effective then any of the protection services. Your only cost is if you apply for credit you have to un-freeze the agency they want to check. I believe it is free to do this once a year and $10 for each additional. Cost varies by state.
There are links to all three agencies here.
