The Impact of Credit Report Errors on Your Score and How to Fix Them

How credit report errors damage your score and your wallet

A single incorrect item on a credit report—such as a missed payment that never happened or a collection account that isn’t yours—can change how lenders view you. Credit scoring models (like FICO and VantageScore) rely on the data in your credit files: payment history, amounts owed, length of credit history, new credit, and credit mix. When that data is wrong, your score and access to favorable interest rates are at risk.

Government and consumer-protection organizations have repeatedly found that a meaningful share of consumers find inaccuracies on at least one of their credit reports; estimates commonly cited are about one in five consumers (Consumer Financial Protection Bureau) (CFPB: https://www.consumerfinance.gov). That doesn’t mean every error will move your score a lot—but some can be expensive. For context, inaccurate late payments, collections, or identity-mixed accounts are the kinds of errors most likely to cause large score declines and lending denials.

How errors influence major score components

• Payment history (largest factor): A falsely reported late or delinquent payment signals heightened credit risk. That can reduce your score by tens or even over a hundred points depending on your baseline score and how recent the delinquency is.
• Amounts owed / utilization: An account reported with an inflated balance or an account you didn’t close can increase your utilization ratio and cut your score.
• Length of credit history: Accounts misreported as new or missing closed-accounts can shorten your average age of accounts.
• New credit and inquiries: Erroneous hard inquiries or duplicate accounts can show as recent credit shopping and lower your score.
• Credit mix and public records: Fraudulent or misattributed public records (bankruptcies, judgments) cause major, long-lasting damage.

Because scores are calculated from a combination of these inputs, the exact point impact varies by scoring model and your credit profile. As a CFP® and financial educator I’ve seen one erroneously reported delinquency drop a middle‑score borrower 60–100 points; for someone already thin-filed, the same error can be equally or more damaging.

Common types of credit report errors

• Identity mix-ups or “mixed files” (someone else’s account appears on your report) — often caused by similar names, SSNs, or clerical errors.
• Incorrect payment history (late payments that weren’t late or were paid) — usually a furnisher reporting mistake.
• Wrong balances or credit limits — inflates utilization.
• Duplicate accounts — can make it look like you have more debt than you do.
• Closed accounts reported as open (or vice versa) — affects utilization and age of accounts.
• Fraudulent accounts opened via identity theft.

Each of these can appear on one or more of the three national consumer reporting agencies’ files (Equifax, Experian, TransUnion), so an error can multiply if it spreads across bureaus.

How to check your reports (quick action steps)

1. Get copies of your reports from all three bureaus. You can get free annual copies at AnnualCreditReport.com; during certain times (e.g., persistent fraud risk), you can get them more often. See finhelp’s guide on how to get a free report: “How to Get a Free Credit Report” (https://finhelp.io/glossary/how-to-get-a-free-credit-report/).
2. Read each report line by line. Use our guide “How to Read Your Credit Report” to spot red flags and understand entries (https://finhelp.io/glossary/how-to-read-your-credit-report/).
3. Note any errors precisely: account number, creditor name, reported balance, dates, and the exact wording of the problem.

Step-by-step: Disputing and fixing errors

Under the Fair Credit Reporting Act (FCRA), you have the right to dispute inaccurate information; consumer reporting agencies must investigate. The typical process:

1. Document the error. Gather account statements, payment receipts, account cancellation confirmations, identity documents, or any proof that shows the entry is wrong.
2. File a dispute with the credit bureau(s) reporting the error. You can dispute online, by phone, or by mail. Filing online is fastest, but sending a paper dispute by certified mail (return receipt requested) creates a clear paper trail. See our page on disputing reports: “Dispute Credit Report” (https://finhelp.io/glossary/dispute-credit-report/).
3. Send supporting evidence with your dispute. If you mail a dispute letter, include copies (never originals) of proof.
4. The bureau forwards the dispute to the furnisher (the company that provided the information). The furnisher must investigate and report back.
5. The bureau must generally complete the investigation within 30 days; in some circumstances they have up to 45 days (FTC guidance on disputing errors: https://www.consumer.ftc.gov/articles/0151-disputing-errors-credit-reports).
6. Review the results. If corrections are made, the bureau must provide a free copy of your report showing the change. If the furnisher verifies the information as accurate, the item stays.
7. If the result is unsatisfactory, escalate: send a follow-up with more evidence, dispute directly with the furnisher, ask the bureau to include a statement of dispute in your file, or file a complaint with the CFPB (https://www.consumerfinance.gov/complaint/).

Sample dispute letter paragraph (concise):

“I am writing to dispute the following item on my [Equifax/Experian/TransUnion] credit report: [Account name and number]. The report shows a [late payment/collection] on [date], but I paid on [date] (see attached bank statement). Please investigate, correct this information, and send written confirmation of the outcome.”

Use certified mail and keep copies of everything.

Identity theft, fraud alerts, and freezes

If an error is the result of identity theft, take additional steps immediately:

• Place a fraud alert (initial alert for one year) or an extended fraud alert (7 years) after filing an identity-theft report with the FTC. Fraud alert contact info is on the bureaus’ sites.
• Freeze your credit to prevent new accounts from being opened without your express authorization. Freezing and unfreezing are free under federal law.
• File an identity-theft report with the FTC and, when appropriate, a police report. See FTC identity-theft resources (https://www.identitytheft.gov/).

The FTC provides step-by-step guidance and templates for identity-theft victims, and the bureaus have dedicated channels for identity-theft disputes.

What to expect after a correction

• Updated credit reports: If the bureau removes or corrects an item, the negative effect should fall off your score as soon as scoring models re-run. You may see your score improve the next time a lender requests your report or when you check your score after the bureau finishes its investigation.
• Letters of confirmation: Credit bureaus and furnishers typically send letters confirming corrections. Keep these in your permanent records.
• Re-aging or re-reporting risk: If a furnisher corrects the error but later re-submits the same inaccurate data, repeat the dispute steps and escalate.

When errors don’t get fixed

If a furnisher insists an item is accurate and the bureaus back them, you still have options:

• Add a brief statement of dispute to your credit file (the bureau must include it when your report is given to a lender).
• File a complaint with the CFPB and the state attorney general’s consumer protection office.
• If the item is defamatory or clearly erroneous and harms you financially, consult an attorney about consumer reporting law remedies; FCRA allows legal action in certain cases.

Professional tips from practice

• Record everything. Note dates, names, and outcomes of each call.
• Use certified mail for initial disputes if you prefer a paper trail.
• Don’t over-argue minor items—prioritize errors that materially affect utilization, payment history, or public records.
• Check all three bureau reports: an item corrected at one bureau may still appear on the other two.

Misconceptions to avoid

• “If I pay, errors won’t matter.” Paying doesn’t erase a false record of a late payment or a fraudulent account.
• “Disputes always fix mistakes.” Most disputes are resolved, but not all — especially when documentation is weak.
• “Bureaus are legally required to delete anything I say is wrong immediately.” Bureaus must investigate but can keep items verified by furnishers.

Final takeaway

Credit report errors are common enough that proactive monitoring is essential. Correcting inaccuracies can produce significant score improvements and save you hundreds or thousands in interest over time. Start by getting all three reports, document what’s wrong, and follow the dispute process. If identity theft is involved, use fraud alerts and freezes and file an identity-theft report.
