Getting negative and inaccurate information off of your credit reports is one of the fastest ways to improve your score. Since credit bureaus have to respond and resolve a dispute within 30 days—a few exceptions can extend this to 45 days—it’s a short timeline. The timeline is particulary important when consumers want to buy a house, get a new car or open up a new credit card and don’t have time to wait to build good credit organically.
If you find information that is incorrect, you can file a dispute. Remember too, that items on your credit report that you don't recognize could also be potential signs of fraudulent activity — someone working to secure credit in your name for their own use. Make sure you're clear on items that could potentially be fraudulent, versus those that may simply be inaccurate.
