TransUnion Dispute: How to Fix Errors on Your TransUnion Report
TransUnion is one of the three national credit bureaus, and it only has to correct what you can show is inaccurate. Here is how a TransUnion dispute actually runs, start to finish.
How a TransUnion dispute works
Identify the exact error
Wrong balance, an account that is not yours, a duplicate, a re-aged date, or an inquiry you never authorized. Write down the account number and what specifically is wrong.
Send a written dispute
A mailed letter under FCRA §611 creates a paper trail an online form does not. Attach your ID and proof of address, and keep a copy of everything you send.
Wait out the 30 days
The bureau has 30 days (45 if you send new documents mid-investigation) to reinvestigate and must delete anything it cannot verify with the furnisher.
Escalate what survives
If an item comes back verified but is still wrong, request the method of verification, dispute directly with the furnisher, or add a consumer statement.
Where to send a TransUnion dispute
By mail
TransUnion Consumer Solutions P.O. Box 2000 Chester, PA 19016-2000Online
transunion.com/credit-disputes — fastest, but leaves a thinner paper trail than mail.
By phone
1-800-916-8800 (weekdays). Phone disputes are the hardest to document.
Mailing details can change — confirm on the bureau's own site before sending.
What is specific to TransUnion
TransUnion often carries different tradelines than the other two
Some furnishers report to only one or two bureaus. An account showing on TransUnion but not on Experian or Equifax is not automatically an error — but a balance or date that disagrees across bureaus usually is.
Online disputes can close fast
TransUnion's portal frequently returns a result in well under 30 days. A quick 'verified' response usually means the furnisher e-confirmed the data, so your next move is a method-of-verification request, not a repeat of the same dispute.
TransUnion powers many rental and employment screens
Because TransUnion data feeds tenant and employment screening products, an error there can cost you an apartment even when the other two reports are clean. Worth prioritizing.
Frequently asked questions
How long does a TransUnion dispute take?
Up to 30 days from the date TransUnion receives it, extended to 45 days if you send additional documents during the investigation. Many online disputes resolve sooner.
Should I dispute with TransUnion online or by mail?
Mail with tracking creates a stronger record if you later need to escalate. Online is faster. If the item is significant, mail it.
What if TransUnion says the item is verified?
Request the method of verification, dispute directly with the furnisher that reported the data, and keep copies. Verified does not mean correct.
