How to Write a Section 609 Letter to TransUnion
A Section 609 letter invokes your rights under 15 U.S.C. § 1681g of the Fair Credit Reporting Act, requiring TransUnion to provide the original documentation supporting any item on your credit report. If TransUnion cannot produce verifiable proof — original signed contracts, complete account histories — the disputed item must be deleted. This is a powerful tool for old or sold-off accounts where the underlying paperwork has been lost.
Where to send this letter
How to find the right address for TransUnion
Mail this letter to the dispute or billing-inquiries address printed on your most recent statement. Look for the section labeled "Billing Inquiries," "Disputes," or "Correspondence" — this is different from the payment address. If you can't find it on your statement, check the company's website or the back of your card for their consumer-correspondence address.
Step-by-step: sending a Section 609 Letter to TransUnion
- Pull your free credit reports from annualcreditreport.com.
- Identify accounts you suspect lack proper documentation.
- Generate your Section 609 letter and attach a copy of your ID and proof of address.
- Mail Certified to the bureau; they have 30 days to verify or delete.
What to expect
30 days under FCRA §611 — bureaus must verify or delete.
Once the bureau receives a properly identified dispute, the FCRA gives them 30 days (45 in limited cases) to verify the item with the furnisher or remove it. Attaching ID and proof of address up front prevents 'unable to verify identity' brush-offs.
Frequently asked questions
What does Section 609 actually require?
It requires consumer reporting agencies to disclose all information in your file, including the source of each item. If they cannot verify with original documentation, the item must be removed.
Do I need to attach my ID?
Yes — bureaus require proof of identity (driver's license + utility bill or bank statement) to process the request.
Can I send the same letter to all three bureaus?
Yes, but each bureau must receive its own copy mailed to its own address. Disputing with one bureau does not trigger updates at the other two.
Can I fax a Section 609 letter to the bureau?
The credit bureaus prefer mailed disputes with attached ID, and mailing certified gives you proof of delivery and the start of the 30-day clock. If a bureau lists a dispute fax number, you can use it, but keep the certified-mail receipt as your record.
