Mossi is correct in that you can pull your score as much as you want yourself online and it does NOT affect your score OR hit you with a hard inquiry. HOWEVER if you read the fine print on ALL online
credit report sites you will find that they ALL use their own scoring model and the scores are not the same as what a lender or financial institution will pull. You as the consumer do not have access to your TRUE FICO scores. The information within your report is correct as your credit information is public information but your scores will rarely be accurate.
Recently for example, Truecredit.com (which is by Trans Union) was forced to change their entire scoring model because it was too similar to FICO's scoring model. A lawsuit was files against them and where their scores used to be one of the closest to your real FICO scores, they are now nearly 100 points off. Remember, this is a site BY TRANS UNION. Your online credit scores are meaningless as they are not based on FICO's scoring model.
