Here's how to improve your credit score by fixing errors on your credit report without any cost.

Errors on your credit report can negatively impact your credit score, making it harder for you to obtain favorable interest rates on loans and credit cards.

Regularly monitoring your credit reports can help you fix mistakes before they negatively affect your credit score.

Your Experian credit report may differ significantly from your TransUnion report.

The three major credit bureaus that generate your credit reports are Equifax, Experian, and TransUnion. However, it is incorrect to assume that they are all the same, as Matt Schulz, the chief credit analyst at LendingTree and author of "Ask Questions, Save Money, Make More," points out.

Lenders have the option to report your activity to different credit bureaus and choose what and when to share.

"Lenders may use different credit reports when evaluating loan applications, which can vary significantly from one report to another, according to Schulz."

It's crucial to keep track of your credit reports for errors, he emphasizes.

How to get your credit reports

Obtain a copy of your credit reports from all three bureaus initially.

You can obtain a free credit report annually from each major credit bureau by visiting annualcreditreport.com. Last year, the three major credit bureaus permanently extended a program that enables you to receive your credit report for free once a week.

Experian recommends reviewing credit reports quarterly or annually.

According to the Consumer Financial Protection Bureau, checking your own report should not negatively affect your score.

Examine your credit report carefully after obtaining it, searching for any inaccuracies, such as unrecognized accounts, incorrect credit limits, or unauthorized hard credit inquiries.

How to flag errors on your credit report

If you find any errors in your credit report, you can file a dispute with the credit bureau that generated the report or contact the business that reported the error directly. You can file disputes by mail or online.

When you file a report, you'll need the following information:

• The creditor's name and account number
• The items on your credit report you think are incorrect
• The reason you believe the reported information is a mistake

Please provide me with your full name, Social Security number, birthday, current address, and any address you've used over the past two years.

According to the Federal Trade Commission, the credit bureau has 30 days to investigate your dispute once you submit it. The bureau will contact the business that reported the potential error, provide it with the evidence you've submitted, and instruct it to begin an investigation.

If the business determines it made a mistake, it must notify each major credit bureau to update your credit report. The credit bureau you submitted the claim to must provide you with the investigation results.

If removing errors from your credit report can increase your credit score, it may be worth the effort despite the apparent difficulty.
