Rule No. 1: Fix your credit for a price? Beware -- especially if it involves creating a new credit identity by using an Employer Identification Number instead of your Social Security number. Another approach involves the idea that negative information has to be removed from your report while it is being challenged; scammers claim by challenging everything, they can get you temporarily clean report. Nearly impossible to accomplish in the first place, nearly impossible to defend later, and just a terrible idea all around, really.

Rule No. 2 If something is inaccurate on your credit report, get it removed. The federal Fair Trade Commission has a sample letter you can use, and be sure to send your letter by certified mail. Include copies of all the documentary evidence you can find.

Rule No. 3 Negative information can stay on your report for seven years (10 years if bankruptcy is involved).

Rule No. 4 Your credit standing is
determined by these factors -- negative
information, outstanding accounts,
credit history and your
use of credit.
