The main number for TransUnion disputes is 1-800-916-8800
TransUnion's dedicated dispute line is 1-800-916-8800. This number connects you to their consumer relations department, which handles credit report errors. You can call this line Monday through Friday, 8 a.m. to 9 p.m. Eastern time. Have your Social Security number and a description of the error ready before you call.
If you prefer not to call, you can also file a dispute online through TransUnion's website or by mail. The online method is often faster — you can upload documents and track your dispute status without waiting on hold. Mail disputes take longer but create a paper trail if you need it later.

What information you need before calling
Gather these details before you dial. You will need your Social Security number to verify your identity. Have the specific account or item on your report that contains the error — the creditor name, account number, and the date the error appeared if you know it. Write down exactly what is wrong: a late payment that was actually on time, an account you never opened, a balance that is incorrect, or an account that should have been removed.
If you have documents that prove the error — a bank statement, a payment confirmation, a letter from the creditor — have those nearby. You do not need to read them over the phone, but the representative may ask you to mail or upload them later. Knowing these details ahead of time keeps the call short and reduces the chance you will have to call back.
How to file a dispute online instead
Go to TransUnion.com and select "Dispute" or "File a Dispute." You will need to create an account or log in if you already have one. The online form asks you to identify which item on your report is wrong and describe the error in your own words. You can upload documents directly — photos of statements, payment receipts, or letters from creditors all work.
Online disputes often move faster because TransUnion's system routes them directly to their investigation team without phone queue delays. You can check the status of your dispute anytime by logging back into your account. TransUnion will send you email updates and a final written decision within 30 days, just as they would with a phone dispute.
Disputing by mail if you prefer a paper record
You can also send a written dispute to TransUnion's mailing address. Request your dispute address by calling 1-800-916-8800 or visiting their website — the address may vary depending on which department handles your specific dispute. Write a clear letter that includes your name, address, Social Security number, the account you are disputing, and a description of the error. Include copies (not originals) of any supporting documents.
Mail disputes take longer — typically 4 to 6 weeks for delivery and processing, plus the 30-day investigation period. However, a mailed letter creates a dated record that can be useful if you later need to prove you filed a dispute. Keep a copy of everything you send and consider using certified mail so you have proof of delivery.
What happens after you file your dispute
Once TransUnion receives your dispute, they have 30 days to investigate. They will contact the creditor or data source that reported the information and ask them to verify it. If the creditor cannot verify the information, TransUnion must remove it. If the creditor confirms the information is correct, it stays on your report.
TransUnion will send you a written response whether the dispute is upheld or denied. If they remove the error, they will also send a corrected copy of your credit report. If they deny your dispute, the letter will explain why and tell you how to add a statement to your report if you disagree with their decision.
If TransUnion denies your dispute
You have options if you believe TransUnion investigated incorrectly or the creditor's verification was wrong. You can file a complaint with the Consumer Financial Protection Bureau (CFPB) at ConsumerFinance.gov. The CFPB investigates complaints about credit reporting agencies and can pressure TransUnion to re-examine your case. Filing a complaint costs nothing and does not require a lawyer.
You can also add a 100-word statement to your credit report explaining your side of the dispute. This statement appears whenever someone views your report and may help if you are explore for credit. Request this through TransUnion's website or by calling the dispute line again.

Frequently Asked Questions
How long does a TransUnion dispute take?
TransUnion has 30 days by law to investigate and respond. If you file online or by phone, you usually see results within 4 to 6 weeks total. Mail disputes take longer because of delivery time — expect 6 to 8 weeks. You can check your dispute status online if you filed through their website.
Can I dispute the same error twice if TransUnion denies it the first time?
Yes, you can file another dispute if you have new evidence or believe the first investigation was incomplete. However, TransUnion may ask you to provide information you did not include the first time. If you file a second dispute with the same information and get the same result, they can mark it as frivolous.
What if the creditor does not respond to TransUnion's investigation?
If the creditor fails to verify the information within 30 days, TransUnion must remove it from your report. This is one reason disputes sometimes succeed — creditors do not always respond to verification requests quickly or at all.
Do I need to pay to dispute an error with TransUnion?
No. Disputing errors on your credit report is free whether you call, file online, or mail a letter. Be cautious of third-party services that charge fees to dispute for you — you can do this yourself at no cost.
Will disputing an error hurt my credit score?
Filing a dispute does not hurt your credit score. The dispute itself does not appear on your report. However, if the error is removed and your score goes up, that is a positive change. If the dispute is denied and the error stays, your score remains the same.
