An error on your credit report — an account that is not yours, a balance you already paid, a late payment that was never late — can quietly cost you a loan approval, a lower interest rate, or even an apartment. The good news is that federal law gives you a clear, free way to fix it, and you do not need to pay a credit-repair company to do something you can do yourself in an afternoon. The Fair Credit Reporting Act (FCRA) requires the credit bureaus and the companies that report your information to investigate disputes and correct what they cannot verify.
This walkthrough takes you through it step by step: how to get your reports for free, how to dispute with both the credit bureau and the furnisher (you should do both), what the roughly 30-day investigation looks like, what happens after, and how to write the dispute itself. This guide explains your general rights, not advice on your specific situation — but the process below is the same one the CFPB and FTC point consumers to.
Step 1: Get your free credit reports
Start by seeing what is actually on your reports. The only official, federally authorized source is AnnualCreditReport.com — it is the only site explicitly directed by federal law to provide them, and it is sponsored by the three nationwide bureaus, Equifax, Experian, and TransUnion. Other sites may charge you or be set up to harvest your personal information, so go directly to the official one.
You are entitled to a free report from each bureau, and the bureaus have made free weekly online reports permanent, so you can check all three regularly at no cost. Pull all three, because an error can appear on one report but not the others, and read each line: personal information, accounts, balances, payment history, and the "hard inquiries" section. Flag anything that is wrong, not yours, or out of date.
- Use AnnualCreditReport.com — the only official source; avoid look-alike sites that charge or phish.
- Pull all three reports (Equifax, Experian, TransUnion); errors often appear on only one.
- Review accounts, balances, payment history, personal details, and inquiries for anything inaccurate.
- Save a copy of each report and note exactly which item is wrong and why.
Step 2: Dispute with the credit bureau
Send a dispute to each bureau that is reporting the error. You can dispute online, by phone, or by mail; many people use mail (often certified, with return receipt) because it creates a dated paper trail. Whichever channel you use, be specific: identify each error, explain clearly why it is wrong, and include supporting documents.
Once it receives your dispute, the bureau must investigate, forward your dispute and all the information you provided to the company that supplied the information (the "furnisher"), and report the results back to you. Include enough to make the investigation easy: your full name and address, the specific account or item, a clear explanation, and copies — never originals — of any proof.
- Equifax — equifax.com/personal/credit-report-services/credit-dispute/ or (866) 349-5191.
- Experian — experian.com/disputes/main.html or (888) 397-3742.
- TransUnion — dispute.transunion.com or (800) 916-8800.
- Include: your name and address, the specific error and account number, a clear reason it is wrong, a copy of the report with the item highlighted, and copies of supporting documents.
Step 3: Dispute with the furnisher too
Disputing with the bureau is essential, but you should also dispute directly with the furnisher — the company that reported the information, such as your bank, credit card issuer, lender, or collection agency. The FCRA gives you the right to dispute with the furnisher as well, and the CFPB recommends doing both, because the furnisher is the source of the data and is independently obligated to investigate.
Send the furnisher a written dispute, ideally by certified mail, that names the specific item, explains why it is inaccurate, and attaches copies of your evidence. A furnisher generally must investigate and respond within 30 days of receiving your dispute. If it confirms the information was wrong or cannot be verified, it must update or remove the information and notify all the credit reporting companies of the correction.
- Write to the furnisher directly (the bank, lender, card issuer, or collector that reported the item).
- Send it in writing — certified mail with return receipt creates proof of the date.
- State the specific item, why it is inaccurate, and attach copies of supporting documents.
- The furnisher generally must investigate and respond within 30 days.
How long does the investigation take?
Under the FCRA, a credit reporting company generally must investigate your dispute within 30 days of receiving it, and it has five business days after completing the investigation to notify you of the results. There are two important wrinkles. If you submit additional information relevant to the dispute during that 30-day window, the bureau can extend the investigation by up to 15 more days. And if you filed the dispute after pulling your free annual report, the period can run up to 45 days.
If the bureau decides a dispute is "frivolous" or "irrelevant," it can stop investigating — but it must notify you and tell you why, so you can address the reason and refile. The 30-day clock is real and enforceable, which is why a dated dispute matters: it establishes when the investigation must conclude.
What happens after the investigation?
When the investigation ends, the bureau sends you the written results and a free copy of your report if the dispute led to a change (this free copy does not count against your regular free reports). If the furnisher confirmed the error or could not verify the information, it must be corrected or removed, and the furnisher must notify the other bureaus of the fix so the correction propagates.
If you disagree with the outcome — the bureau says the information is accurate but you still believe it is wrong — you have options. You can ask that a brief statement of dispute be added to your credit file so anyone reading the report sees your side, you can dispute again with new evidence, and you can escalate by filing a complaint with the CFPB online or at (855) 411-2372. Persistent, documented disputes backed by evidence are what move stubborn errors.
How to write the dispute letter
A good dispute letter is short, factual, and specific. It identifies you, names exactly which item is wrong and why, states what you want done (corrected or removed), and lists the documents you are enclosing. Keep the tone matter-of-fact — you are asserting a right, not making a plea — and never send originals of your evidence; send copies and keep the originals.
Send a version to the bureau and a version to the furnisher, keep a dated copy of each, and use a channel that proves when you sent it. Note that this is about inaccurate information on your credit report under the FCRA — it is different from demanding that a debt collector validate a debt, which is a separate right under the Fair Debt Collection Practices Act. When you need to put the dispute in the right format quickly, you can generate a credit dispute letter to send to the bureau and the furnisher.
- Identify yourself: full name, address, and (if asked) report or file number.
- Name the error: the specific account or item and a clear reason it is inaccurate.
- State the remedy: correct it or delete it.
- Enclose copies of supporting documents — never originals — and keep a dated copy of everything.
The bottom line
Disputing a credit report error is free and entirely doable yourself. Pull your reports from AnnualCreditReport.com, then dispute the error in writing with both the credit bureau and the furnisher that reported it. The FCRA requires the bureau to investigate — generally within about 30 days — and to correct or remove anything it cannot verify, then notify you of the results. If you disagree with the outcome, add a statement of dispute, refile with new evidence, or complain to the CFPB. Keep it factual, keep copies, and use a channel that proves the date; a clear, dated credit dispute letter to the bureau and the furnisher is what gets a wrong entry fixed.
