TransUnion Fax Number — Fax Credit Disputes and Reports

TransUnion accepts faxed dispute letters, identity theft affidavits, and credit freeze requests, though the fax number varies by the department handling your matter. Because a credit dispute often hinges on timing, having a dated confirmation that TransUnion received your paperwork can matter as much as the dispute itself. Call TransUnion to confirm the correct fax line before you send sensitive financial records.

What You Can Fax to TransUnion

  • Credit report dispute letters
  • Identity theft affidavits
  • Fraud alert requests
  • Credit freeze/thaw requests
  • Supporting documentation for disputes
Tip: Each page should carry your full name, the last four digits of your Social Security number, your date of birth, and your current address so TransUnion can match the documents to your credit file. Many people send disputes by certified mail and fax both, which creates two independent records of submission. Hold onto the Send FAX Mail confirmation as evidence of the date your dispute went through.
