Today I opened my mail box and realized the amount of credit card and auto insurance offers are almost non-existent. A few weeks ago, I called the national opt-out toll free number and entered my personal information. I was a bit skeptical that this would actually reduce the amount of offers that would pile into my mail box. However, it actually works.
The national credit reporting agencies have a one stop website OptoutPrescreen.com. Visit this website to get more information on opting out.
