Mistakes on credit reports are more common than most people expect—and even a small error can affect your ability to qualify for a loan, rent an apartment, or get better interest rates. The good news: disputing credit-report errors is free, and federal rules give you a clear process to follow.
This guide walks you through what to do, what to send, and what happens after you file a dispute.
Step 1: Find the exact error and gather proof
Before you dispute anything, make sure you can clearly identify:
- Which credit report contains the mistake (not all three reports always match)
- Which item is wrong (account, balance, payment status, personal info, etc.)
- What the correct information should be
- What documents support your claim (receipts, statements, letters, identity documents, police/identity theft reports if applicable)
When you file, you’ll want to include copies (not originals) of any supporting documents.
Step 2: Dispute the error with the credit bureaus that show it
If the mistake appears with one bureau, dispute it with that bureau. If it appears with multiple bureaus, dispute it with each one.
You can usually dispute:
- Online
- By phone
- By mail
Why disputing by mail can be useful
Mail disputes can be easier to document because you can keep a paper trail. Guidance commonly recommends sending your dispute by certified mail with return receipt so you can prove it was received.
What your dispute letter should include
A strong dispute letter typically asks the bureau to remove or correct the inaccurate or incomplete information and includes:
- Your full name and address
- A clear list of each item you’re disputing and why
- A copy of your credit report with the disputed items circled
- Copies of documents that support your dispute
- A request for a corrected copy of your report if changes are made
(There are also official sample letters you can use as a framework.)
Step 3: Dispute the error with the company that reported it
The credit bureau isn’t the only place to dispute. You can also dispute directly with the business that supplied the information (sometimes called the “furnisher”), especially if the issue is tied to an account record, payment history, or balance.
Just like with bureaus, it helps to:
- Put your dispute in writing
- Include copies of evidence
- Send it certified mail if possible, so you can document delivery
Step 4: Know the investigation timeline (and what “frivolous” means)
After a bureau receives your dispute, it generally has 30 days to investigate.
A bureau may stop investigating if it decides your dispute is “frivolous” or “irrelevant.” If that happens, it must notify you and explain why—often because you didn’t provide enough detail or evidence.
If you get a “frivolous” notice: respond with additional documentation and a clearer explanation.
Step 5: What you should receive after the investigation
Once the investigation is done, the bureau must send you the results in writing. If your dispute leads to a change, you’re entitled to a free updated credit report (separate from your free annual report).
You can also request that the bureau send correction notices to:
- Anyone who received your report in the past six months, and
- Anyone who received it for employment purposes in the past two years
Common mistakes people make (and how to avoid them)
Mistake: Disputing without evidence
Fix: Send copies of statements, letters, receipts, or identity documents that support your position.
Mistake: Only disputing with one bureau
Fix: Dispute with every bureau that shows the error.
Mistake: Sending originals
Fix: Send copies only; keep originals for your records.
Mistake: Not keeping records
Fix: Keep a folder with letters, screenshots, tracking numbers, and return receipts.
A simple dispute checklist you can copy/paste
- Pull your reports and highlight each error.
- Gather supporting documents (copies).
- Write a dispute letter for each bureau involved.
- Send by certified mail + return receipt (optional but helpful).
- Dispute with the company that furnished the data (if applicable).
- Track dates—expect results within about 30 days.
- Review the outcome and follow up if the correction wasn’t made.
