TransUnion's dispute phone line and what to expect when you call
TransUnion's dedicated dispute line is 1-800-916-8800. When you call, you'll reach an automated system that routes you to a representative who handles credit report disputes. The line is open Monday through Friday, 8 a.m. to 9 p.m. Eastern time. Have your Social Security number and a copy of your credit report in front of you before you call — the representative will ask for both.
The representative will ask you to describe the item you're disputing and why you believe it's wrong. They'll take notes and explain what happens next: TransUnion sends your dispute to the company that reported the information (your creditor, a collection agency, or another data furnisher). That company then has 30 days to respond. If they don't respond or can't verify the information, TransUnion removes it from your report.
Calling is faster than mailing a dispute letter, but both methods are equally valid. If you prefer a written record or want to dispute multiple items at once, you can also mail a dispute letter to TransUnion's address, which appears on your credit report.

What information you need before calling
Gather these items before you dial: your Social Security number, the account number or reference number of the disputed item (if you have it), and your credit report itself. You can get a free copy of your TransUnion report at annualcreditreport.com, which is the official site run by all three credit bureaus.
Write down the specific reason the item is wrong. For example: "This account was paid in full in 2019 but still shows as open," or "This is not my account — I never opened it." The more specific you are, the easier it is for the representative to document your dispute accurately.
Disputes by mail instead of phone
If you don't want to call, you can mail a dispute letter to TransUnion. Your credit report includes TransUnion's mailing address. Write a short letter that includes your name, address, Social Security number, and the specific item you're disputing. Explain why you believe it's inaccurate and include a copy (not the original) of any supporting documents — a paid receipt, a letter from the creditor, or a police report if the account is fraudulent.
Mail your letter certified with return receipt requested so you have proof TransUnion received it. Keep a copy for your records. The process takes longer by mail — typically 30 to 45 days instead of a few weeks — but you'll have documentation that you sent the dispute on a specific date.
What happens after you file a dispute
TransUnion sends your dispute to the company that reported the information. That company (called the "data furnisher") then investigates. They either confirm the information is correct, correct it, or say they can't verify it. If they can't verify it within 30 days, TransUnion must remove it.
You'll receive written notice of the results by mail, usually within 30 to 45 days. The notice will tell you whether the item was removed, corrected, or verified as accurate. If it was verified, you have the right to add a 100-word statement to your credit report explaining your side of the dispute.
Disputing fraudulent accounts or identity theft
If you're disputing an account you didn't open, tell the representative you believe it's fraudulent. TransUnion may flag it for faster investigation. You should also file a report with the Federal Trade Commission at identitytheft.gov and consider placing a fraud alert or credit freeze on your report.
A fraud alert tells creditors to take extra steps to verify your identity before opening new accounts. It lasts one year and is free. A credit freeze locks your report so no one can open new accounts in your name without your permission. Both are available through TransUnion's website or by calling the dispute line.
If you disagree with the dispute results
If TransUnion says the item is verified as accurate but you still believe it's wrong, you can dispute it again. You can also add a 100-word consumer statement to your report explaining why you think it's inaccurate. This statement appears whenever someone views your report.
You also have the right to file a complaint with the Consumer Financial Protection Bureau (CFPB) if you believe TransUnion mishandled your dispute. The CFPB investigates complaints about credit bureaus and can force corrections if they find an error.
Frequently Asked Questions
How long does it take to hear back after I call the dispute line?
TransUnion sends your dispute to the reporting company within a few business days. You'll receive written results within 30 to 45 days. The 30-day clock starts when the reporting company receives the dispute, not when you call TransUnion.
Can I dispute the same item more than once?
Yes, but only if you have new information or evidence. If you dispute the same item with no new details, TransUnion may dismiss it as frivolous. If the item is verified again, wait at least a few months before disputing a third time.
What if TransUnion says they can't find the item on my report?
This sometimes happens if the item was already removed or if there's a name mismatch. Ask the representative to search again using different variations of your name or the account number. If it's truly not there, the dispute is closed and you don't need to do anything else.
Do I need to pay for a dispute?
No. Disputing with TransUnion is free whether you call or mail a letter. Be cautious of third-party services that charge fees to dispute on your behalf — you can do it yourself at no cost.
Will disputing hurt my credit score?
No. Disputing an item does not lower your score. Your score may improve if the item is removed, but it won't drop because you filed a dispute.
