Annually I try to remember to check my credit on the site that gives you free credit information from the big three companies once a year. A couple years ago there was a negative that showed up that was not mine. It took me a while, but I got it removed as it pays to check. THey want to charge for the FICO score so I very seldom get it. A score of 850 is good as it gets and anything over 800 is great.
