You should contact both the credit bureaus (like Equifax, Experian, and TransUnion) and the company that reported the incorrect information, and you should do it in writing whenever possible (online or by mail, with mail often being the strongest option).

Quick Scoop: Credit Report Mistake

Finding a mistake on your credit report feels a bit like seeing a stranger’s name on your house keys—small detail, big consequences. The good news is there’s a clear process for getting it fixed.

Who you should contact

You generally have to go after the error from two directions at the same time.

  1. The credit reporting company (credit bureau)
    • Equifax, Experian, and/or TransUnion—whichever report shows the error.
 * They are required to investigate disputes and correct or remove inaccurate information if they confirm it’s wrong.
  1. The “furnisher” (the company that reported the info)
    • This is usually a bank, credit card company, lender, collection agency, or service provider that sent the data to the bureau.
 * Contacting them helps make sure the bad data doesn’t just get re‑reported later.

Think of it like fixing a leaking ceiling: you talk to the building manager (credit bureau) and the person whose pipe is leaking upstairs (furnisher), not just one of them.

How to contact the credit bureaus

You can dispute errors online, by mail, or by phone , but written disputes (especially by mail) give you the strongest paper trail.

1. Online (fast, but less paper trail)

Most bureaus let you file disputes through their websites.

  • Equifax: Online dispute portal via their credit dispute page.
  • Experian: Online dispute portal via their disputes page.
  • TransUnion: Online dispute site (dispute.transunion.com).

Online is convenient and quick, but some consumer attorneys warn that online systems may limit how you describe the issue or upload evidence, and you may be agreeing to fine‑print terms you don’t fully read.

2. By mail (strongest option)

Mailing a dispute letter gives you proof of what you sent and when.

  • Send a written dispute letter to each bureau that shows the error.
  • Use certified mail with return receipt so you have proof they received it.
  • Keep copies of everything you send—letter, documents, and your credit report pages with the errors highlighted.

Your letter should include:

  • Your full name, address, and phone number.
  • Credit report confirmation number (if you have one).
  • Each item you’re disputing (with account numbers if applicable).
  • A clear explanation of what is wrong and why (e.g., “This account is not mine,” “This payment was made on time”).
  • A specific request to remove or correct the item.
  • Copies (not originals) of supporting documents (payment records, letters from your lender, ID, police report in case of identity theft, etc.).
  • A copy of the report page with the error circled or highlighted.

3. By phone (usually least recommended)

You can technically dispute by phone using the numbers listed by each bureau, but most experts advise against relying on phone disputes alone because:

  • You don’t get the same detailed written record of what you said.
  • It’s harder to prove later exactly what you reported and when.

If you do call, follow up with a written dispute to lock in your evidence trail.

How to contact the company that reported the info

While you’re disputing with the bureaus, you should also reach out to the business that supplied the inaccurate information.

Who counts as the “information provider”?

  • A bank or credit card company reporting late payments.
  • A lender reporting a default or collection.
  • A collection agency reporting a collection account.

They’re often called “furnishers” in credit law.

How to reach them

  1. By mail (preferred)
    • Look on your credit report for a dispute address for that company; if one is listed, use it.
 * If no special address is listed, call the company and ask for the correct address for credit report disputes.

 * Send a written dispute explaining exactly what is wrong, why, and what you want corrected, with copies of your supporting documents.
  1. Online or customer portal
    • Some lenders let you submit disputes through their websites or secure message centers.
 * Even if you do this, consider also sending a physical letter so you have independent documentation.
  1. Phone (supporting role only)
    • Phone calls can help you clarify what the company thinks is going on or ask where to send a dispute.
 * But again, follow up in writing so there’s a record.

Your letter to the information provider should include:

  • Your full name and address.
  • The specific account(s) you’re disputing.
  • What information is wrong and why.
  • Copies of your supporting documents.
  • A clear request to fix the error and to report the corrected information to all relevant credit bureaus.

Mini step‑by‑step plan

Here’s a simple “today and this month” roadmap you could follow.

  1. Gather evidence
    • Download or print your credit report(s) and circle the errors.
 * Collect proof: payment receipts, bank statements, letters, police report (if identity theft), ID, etc.
  1. Write dispute letters to each bureau showing the error
    • Include all the details and copies of your proof.
 * Send by certified mail with return receipt.
  1. Send a similar dispute letter to the information provider
    • Use the address listed on your report or a dispute/address you confirm with them.
 * Attach copies of the same proof.
  1. Wait for investigations and follow up
    • Credit bureaus typically have a limited window (often around 30 days) to investigate in many cases.
 * They should send you results and a free copy of your corrected report if a change is made.
  1. If they don’t fix the mistake
    • You can add a brief statement of dispute to your file and consider speaking with a consumer law attorney or legal aid for advice, especially if the error is serious or causing denials.

Multiple viewpoints you’ll see in forums and “latest news” style

discussions

People online and in recent explainers tend to fall into a few camps on the “how should you contact them?” question.

  • “Mail is king” crowd
    • Often lawyers and experienced consumers who strongly prefer certified mail because it creates a clear record and avoids some online‑portal limitations.
* They see mailed letters as a level playing field where you control the wording and proof you provide.
  • “Use the online portals, it’s faster” crowd
    • Many everyday users prefer the convenience and speed of submitting disputes online and getting status updates quickly.
* This can work especially well for simpler issues (like a wrong address or obviously duplicated account), as long as you save screenshots and confirmations.
  • “Call first, then write” crowd
    • Some people like to call the lender or bureau to understand what’s showing up and why, then follow it up with a written dispute.
* This can help you avoid mistakes in your letters and gather extra documentation before you dispute formally.

Across these viewpoints, the common thread is: however you start, you should end up with clear, written documentation of your dispute and the evidence you provided.

Simple answer in one line

If you see a mistake on your credit report, contact both the credit bureau(s) that show the error and the company that reported it, preferably in detailed written disputes sent online or, even better, by certified mail with supporting documents.
