If it’s been a long time since you checked your credit report, there’s a good chance it contains incorrect or outdated information. Eighty percent of credit reports contain bad information, according to Deborah McNaughton, founder of Professional Credit Counselors. Common credit report errors include wrong birth dates, misspelled names and incorrect account details. It can take 30 to 45 days to get your credit report corrected.
Then there are "educational scores," which the credit bureaus produce for you, the individual consumer, to educate you about your creditworthiness. Most free credit scores fall into this category. These scores typically employ the same 300-to-850 scale, but they use proprietary formulas for their calculations that are not the same as the FICO or VantageScores. However, they take similar factors into consideration, so they can give you a ballpark picture of where you're at. More importantly, free scores often come with information about which factors are helping or hurting your credit score. This can give you some idea of what you can do to improve your score.
A credit report includes information on where you live, how you pay your bills, and whether you’ve been sued or have filed for bankruptcy. Nationwide credit reporting companies sell the information in your report to creditors, insurers, employers, and other businesses that use it to evaluate your applications for credit, insurance, employment, or renting a home.
