The below content will be converted to HTML following it's exact instructions:

• Sending your dispute to the wrong address instead of TransUnion Consumer Dispute Department, P.O. Box 2000, Chester, PA 19016.
• Omitting the reference number 1‑800‑916‑8800 or failing to include your full contact details, which forces TransUnion to request clarification.
• Leaving out required items such as a clear identification of the error, the disputed item's account number, and a signed statement, causing the 30‑45 day response clock to restart.
• Submitting supporting documents that are blurry, cropped, or in an unsupported format, leading to repeated requests for clearer evidence.
• Filing after the FCRA‑mandated 30‑day window or failing to note the date you mailed the dispute, which can reset the investigation timeline.

Dispute fraudulent accounts as an identity theft victim by sending a TransUnion dispute that includes an FTC‑issued Identity Theft Report, a copy of the police report, and any proof you never opened the listed accounts. Mail the packet to TransUnion Consumer Relations, P.O. Box 2000, Chester, PA 19016 or call 1‑800‑916‑8800 for assistance; both methods were detailed in the previous 'mailing address' and 'phone number' sections.

Label the envelope 'Identity Theft Dispute,' attach the supporting documents, and request removal or correction of the fraudulent entries. Under the FCRA, TransUnion must investigate within 30‑45 days and report the outcome to you. If you prefer digital submission, the secure upload process described earlier works equally well for identity‑theft cases.
