How to Dispute Credit Report Errors (Step-by-Step Guide)

Roughly one in five people has an error on at least one of their credit reports significant enough to affect their score, according to a widely cited FTC study. A wrongly reported late payment, an account that isn’t yours, or a balance that’s years out of date can quietly cost you a better interest rate, a card approval, or even an apartment. The good news: fixing it is free, doesn’t require a lawyer, and usually takes a few weeks.

Step 1: Pull All Three of Your Credit Reports

You have three separate credit reports — one each from Equifax, Experian, and TransUnion — and they don’t always match, because not every lender reports to every bureau. Get all three, free, at annualcreditreport.com, the only site mandated by federal law for free reports. Avoid lookalike sites that charge or push a “free trial” that bills you later.

If you haven’t checked your report in a while, it’s worth reading our guide to what actually makes up your credit score first, so you know which sections matter most.

Step 2: Read Every Line, Not Just the Summary

Errors hide in the details. Go through each report line by line and look for:

• Accounts that aren’t yours — a sign of a mixed file (someone with a similar name) or, less commonly, identity theft
• Late payments you actually paid on time — check the exact date against your bank records
• Accounts listed as open that you closed years ago
• Incorrect balances or credit limits, which can distort your utilization ratio
• Duplicate accounts, where the same debt appears twice, sometimes after being sold to a collection agency
• Outdated negative items — most negative marks must fall off after 7 years (bankruptcies after 10)
• Incorrect personal information, like an old address or misspelled name, which can indicate a mixed file even if nothing else looks wrong

Highlight everything questionable before moving to the next step — you’ll often find more than one error once you’re looking closely.

Step 3: File the Dispute With Each Bureau

Errors must be disputed separately with whichever bureau’s report contains them — fixing it on Experian doesn’t automatically fix it on Equifax or TransUnion. Each bureau has its own online dispute portal:

For each dispute, you’ll need to:

1. Identify the specific item you’re disputing
2. Select a reason (not mine, paid off, incorrect amount, etc.)
3. Attach supporting documentation — bank statements, payment confirmations, a police report for identity theft, or anything proving your version of events

Be specific rather than vague. “This account isn’t mine” with no further detail gets investigated more slowly than “This account isn’t mine — I’ve never held an account with [creditor], and my bank records from [date range] show no such account was opened.”

Step 4: Wait Out the Investigation

By law, the bureau has 30 days to investigate (45 days if you submit more information partway through). During the investigation, the bureau contacts the “furnisher” — the bank, lender, or collector who originally reported the item — and asks them to verify it. If the furnisher can’t verify it, the item must be removed or corrected.

You’ll receive written results either way, along with a free updated copy of your report if the dispute changes anything.

Step 5: Escalate if the Dispute Is Denied

If the bureau sides with the furnisher and keeps the item on your report, you have a few options:

• Add a statement of dispute — a short note attached to the item explaining your side, which future lenders will see
• Dispute directly with the furnisher, using the address on your statement or a certified letter to their dispute department
• File a complaint with the CFPB at consumerfinance.gov — this routes your complaint directly to the company and often gets faster, more thorough responses than a standard bureau dispute
• Consult a consumer protection attorney if the error is causing real financial harm (denied mortgage, major rate increase) — many offer free consultations, and the Fair Credit Reporting Act allows you to recover damages in some cases

What Fixing an Error Can Actually Do to Your Score

The impact depends on what’s removed. A wrongly reported 30-day late payment can be worth 60–100 points on its own. An account that isn’t yours, especially a collection account, can be worth even more once it’s gone. If you’re working on your score for a specific goal — a mortgage application, a lower interest rate — checking your report for errors before you apply is one of the highest-leverage, lowest-effort moves available, and it costs nothing.

If your report is clean but your score still needs work, or if you’re just getting started, our guide to building credit from scratch covers the fundamentals step by step.

A Quick Note on Credit Repair Companies

You do not need to pay anyone to dispute an error on your behalf. Credit repair companies charge monthly fees to do exactly what’s described above — something you can do yourself for free in about 20 minutes per bureau. If you’re dealing with a large volume of errors from identity theft, the FTC’s identitytheft.gov walks through the free recovery process, including pre-filled dispute letters.

The Bottom Line

Checking your credit report isn’t a once-a-year chore — it’s a direct way to protect your score from mistakes that aren’t your fault. Pull all three reports, read them closely, dispute anything wrong with documentation, and don’t pay for a service that does nothing you can’t do yourself for free.
