How to Dispute an Error with TransUnion (Step-by-Step)
AI-assisted drafting, human-reviewed and source-checked before publication — how we create content.
TransUnion is one of the three nationwide credit bureaus and is widely used by mortgage lenders, auto finance companies, and apartment screening services. Their dispute process mirrors Equifax and Experian — same FCRA rights, same 30-day clock, different address. Here's exactly how to file, what to include, and how to escalate if TransUnion drops the ball.
Three ways to dispute with TransUnion
Online: transunion.com/credit-disputes via your free TransUnion account. Most disputes resolve in 15–25 days.
By mail: TransUnion Consumer Solutions, P.O. Box 2000, Chester, PA 19016. Use USPS certified mail with return receipt for proof of delivery and to start the 30-day FCRA clock on a verifiable date.
By phone: 800-916-8800. Useful for simple items but leaves the weakest paper trail. Use writing for any high-stakes dispute.
What to include in your dispute
Full legal name, current address, date of birth, and last four digits of your SSN.
Creditor name, partial account number, and the specific field that's wrong.
A factual explanation of the inaccuracy.
Supporting evidence: bank statements, settlement agreements, court records, identity theft reports.
A clear demand for deletion or correction under FCRA Section 611.
After you file: TransUnion's process
TransUnion forwards your dispute to the furnisher within 5 business days under FCRA §1681i(a)(2).
The furnisher investigates and reports back to TransUnion.
Items the furnisher cannot verify must be deleted or corrected.
TransUnion sends you the results in writing within 30 days (45 if you submitted new evidence mid-investigation), plus a free updated report if anything changed.
How to dispute a TransUnion credit report error
- STEP 1
Pull your TransUnion report
Get a free copy at AnnualCreditReport.com. Save as PDF and reference exact data when writing.
- STEP 2
Pinpoint the exact inaccuracy
Identify the specific field that's wrong: account balance, payment history grid, date of first delinquency, status, account holder name, or a fully fabricated entry.
- STEP 3
Gather supporting evidence
Payment confirmations, settlement letters, identity theft reports, court records, or anything else that disproves the reported information.
- STEP 4
Write the dispute letter
Include identifying info, the disputed item, factual explanation, attached evidence, and a request for deletion within 30 days under FCRA §611.
- STEP 5
Send certified mail with return receipt
TransUnion Consumer Solutions, P.O. Box 2000, Chester, PA 19016. Keep both receipts as your legal proof of when the FCRA clock started.
- STEP 6
Escalate to CFPB if TransUnion fails to act
File a complaint at consumerfinance.gov/complaint. CFPB-tracked complaints typically receive bureau responses within 15 days.
Frequently asked questions
What to gather first
- A current copy of each credit report you want to review (Equifax, Experian, TransUnion) from AnnualCreditReport.com.
- Government-issued photo ID and proof of current address, which bureaus commonly request with a mailed dispute.
- Account statements, payment records, or letters that relate to the item you believe is inaccurate or incomplete.
- The exact account name, partial account number, and the reason you believe the entry is inaccurate or incomplete.
- A way to keep records: copies of what you send and, if mailing, proof of delivery.
Common mistakes to avoid
- Disputing information you know is accurate — that wastes the process and does not help you.
- Sending a vague dispute. Identify the specific item and explain what is inaccurate or incomplete.
- Disputing with only one bureau when the same entry appears on more than one report.
- Keeping no copies of what you sent, so you cannot show what was disputed or when.
- Paying a company that promises deletions or score increases — no one can promise those outcomes.
When to get additional help
Consider additional help if a bureau or furnisher does not respond, if an entry you believe is inaccurate stays on your report after a reinvestigation, if you may be affected by identity theft, or if you have questions about your legal rights.
- Submit a complaint to the Consumer Financial Protection Bureau.
- Report suspected identity theft at IdentityTheft.gov (FTC).
- For legal questions, consider consulting a licensed attorney in your state. This page is educational information, not legal advice.
