How to mail a TransUnion credit dispute
PostalForm's paid TransUnion credit-dispute packet workflow is currently unavailable. Use TransUnion's current official dispute instructions and the CFPB's free sample letters instead.

Drag and drop your document or upload from phone.
Add addresses
Enter sender and recipient addresses with validation.
Checkout
We print and mail it via USPS with your chosen options.
Official starting point
Open TransUnion's mail-dispute instructions immediately before sending. Confirm the current address, identity-verification requirements, and accepted documents there. Addresses and requirements can change.
The CFPB's sample-letter page provides a free letter you can adapt.
Prepare the dispute
Identify the item exactly as it appears on your TransUnion report. Explain what is inaccurate or incomplete, why you believe it is wrong, and the correction you want. Follow TransUnion's current instructions and include relevant copies of supporting records.
A packet commonly includes:
- your signed dispute letter or TransUnion's current form
- the report or confirmation number, if available
- a marked copy of the relevant TransUnion report section
- copies of relevant supporting evidence
- the identity and address documents TransUnion currently requests
Send copies, not originals. Keep an exact copy of the outgoing packet.
Mail and retain proof
Use the mailing method you choose after reviewing TransUnion's instructions. Certified Mail is optional, but it can create a mailing and delivery record. Save the address used, receipt, tracking history, response, and updated report together.
If the same error also appears on Equifax or Experian, those bureaus require their own separately addressed disputes. Do not send one envelope to multiple bureaus.

Which mailing option and proof should you choose?
PostalForm offers U.S. letter mailing with different delivery and proof options. First-Class suits routine correspondence; Certified Mail adds mailing and delivery records, and Electronic Return Receipt adds a downloadable signature record. Expedited delivery prioritizes speed. Review the destination, estimated dates, total price, and required proof before paying.
| Mailing option | Delivery speed | Proof | Use when | Avoid when |
|---|---|---|---|---|
| USPS First-Class Mail | First-Class Mail delivery estimate shown before payment. | Available processing scans; no recipient signature or Certified Mail receipt. | Routine letters when a signed delivery record is unnecessary. | Your instructions require Certified Mail, a signature, or a deadline this estimate cannot meet. |
| Certified Mail | First-Class delivery speed; certification does not make delivery faster. | USPS mailing and delivery/attempt tracking; no Electronic Return Receipt unless added. | You need a recorded mailing and delivery or attempted-delivery status. | You need a downloadable signature record or faster delivery. |
| Certified Mail + Electronic Return Receipt | First-Class delivery speed; signature collection may require redelivery or pickup. | Certified Mail records plus a downloadable USPS signature record when available. | Your instructions call for Certified Mail with Return Receipt or you need the signature record. | Your recipient requires an original enclosure, personal service, or another submission method. |
| Expedited / Express with signature | Faster estimated delivery range shown at checkout; production cutoff and destination apply. | Carrier tracking and signature option; this is separate from Certified Mail and ERR. | Speed and signature matter and checkout offers the service for your destination. | A rule specifically requires Certified Mail or the displayed estimate misses your deadline. |
Availability and delivery estimates depend on the document and destination. Mailing proof does not establish that a recipient accepted a filing or that legal service requirements were met. Delivery estimates · Full pricing
