Start Free AnalysisWhen Mailing Makes Sense
- You want proof of delivery and a dated paper trail you control.
- You need to attach supporting documents the online portal won't accept.
- You are disputing the same item again after an earlier response.
- You are requesting the method of verification after an item was marked verified.
Common Mistakes to Avoid
- Sending originals instead of copies of your documentation.
- Disputing several unrelated items in one vague paragraph instead of listing each item separately.
- Leaving out proof of identity and address, which can lead to the dispute being returned as unprocessable.
- Mailing to a general TransUnion corporate address instead of the consumer dispute address listed above.
- Not keeping a copy of what you sent and the certified mail receipt.
