A mistake on your credit report can sit there for months if you never look. The good news is that fixing one follows a fairly clear path. You find the error, you tell the right companies in writing, and you keep track of the clock. This guide walks through that process in plain English, based on guidance from the Consumer Financial Protection Bureau (CFPB) and the Federal Trade Commission (FTC).

The steps below assume you already have a copy of your credit report in hand. You can read it line by line. Many people find that a quick scan turns up something that does not belong, such as a closed account still marked open or a late payment that never happened.

Know what kinds of errors to look for

Start with the basics. Errors on a credit report usually fall into a few groups. Identity errors include a wrong name, phone number, or address. These can signal that someone else's information has been mixed into your file. A mixed file happens when accounts that belong to a person with a similar name end up on your report.

Account-status errors are common and can have a real effect on your file. Examples include a closed account still listed as open, being shown as the owner of an account when you were only an authorized user, late or delinquent marks that do not match your payment history, and wrong dates for when an account was opened, when the last payment was made, or when a delinquency first appeared. Data errors involve numbers, such as the same debt listed twice, a current balance that is off, or a credit limit that does not match the account. Your own statements are the best tool for checking these figures.

If you see accounts you do not recognize at all, that may point to identity theft. The FTC and CFPB treat that as a separate situation with its own reporting steps. The federal government's central resource for it is IdentityTheft.gov, so start there if you suspect fraud.

Send the dispute in the right order

The first step is to dispute the error with the credit reporting company that shows it. The three nationwide companies are Experian, Equifax, and TransUnion. Each one keeps its own file, so an error that appears on one report may also appear on another. You may need to dispute it with each company separately.

Put your dispute in writing. Explain what is wrong and why you think so. Include copies of documents that back up your position, such as statements or payment records. Send copies, not originals, and keep a complete set of everything you mail. The CFPB and the FTC both publish sample letters, which can help you organize your request. A mailed dispute should include your full name, address, and phone number, the confirmation number from your report if you have one, each error with the account number for any disputed account, the change you want made, a marked copy of the relevant part of your report, and your supporting documents. Sending the letter by certified mail with a return receipt gives you proof that the company received it.

The second step is to contact the furnisher. A furnisher is the lender or company that provided the information to the credit bureau in the first place. Furnishers have their own duties to correct inaccurate information they report, so a dispute with the bureau alone may leave the original source uncorrected. Send your explanation to the furnisher too, and keep a dated record of that contact.

Watch the clock

Under federal rules, a credit reporting company generally must complete its investigation within 30 days of receiving your dispute. Write down the date you sent your letter. That single note makes it much easier to tell whether the company is on schedule.

The timing can shift in a few situations. If you filed the dispute after receiving your free annual credit report, the company may take up to 45 days. If you send new, relevant information during the 30-day window, the investigation can be extended by 15 more days. Once the investigation is finished, the company has five business days to tell you the results. You should get written notice along with a copy of your updated credit report. That updated copy does not count as your annual free report, so do not assume it resets your yearly allowance.

When a furnisher corrects wrong information after your dispute, it must pass that correction along to every credit reporting company that received the bad data. The sources do not say how long a correction takes to show up on a later report, or how it might affect a credit score. Those details are worth confirming directly with the bureau.

If the result is not what you expected

Read the written results carefully and compare them with your own records. If the outcome does not match what you believe is correct, the process does not have to end there. When you dispute with a credit reporting company, you can ask that a statement of your position be added to your file. Future readers of your report can then see your side of the disagreement, even if the item itself stays.

Federal law also includes remedies when a company fails to follow the rules. A consumer who wins in court may be able to recover damages and attorney fees, and in cases of willful noncompliance, the law may allow actual or statutory damages and punitive damages. Lawsuits under the Fair Credit Reporting Act are subject to time limits, so anyone thinking about that route should look up the deadlines right away and consider getting qualified legal guidance. Keep in mind that credit reporting companies are not required to investigate a dispute they consider frivolous. A specific, factual letter backed by documents is far less likely to be dismissed that way.

Before you hit send

Before you mail anything, run through a short checklist. Did you dispute with each bureau that shows the error? Did you contact the furnisher as well? Does your letter include your contact details, the confirmation number, each error with its account number, a clear explanation, the change you want, a marked report copy, and copies of your proof? Did you note the date you sent it so you can track the 30-day window?

Then keep the paper trail going after you send it. Save the return receipt, the bureau's written results, and the updated report. If the answer does not add up, you will have the dates and documents you need to ask questions. For current mailing addresses and phone numbers for the bureaus, check their official websites or the CFPB and FTC guidance directly, since the sources behind this article do not list them.
