    AI-assisted drafting, human-reviewed and source-checked before publication — how we create content.

    Reaching the right credit bureau at the right address is half the battle when disputing errors. This directory lists the verified phone numbers, mailing addresses for written FCRA disputes, and official online portals for Equifax, Experian, and TransUnion.

    Equifax contact information

    Consumer phone: 1-888-378-4329 (1-888-EQUIFAX). Fraud alerts and security freezes: 1-888-548-7878.

    Written dispute mailing address: Equifax Information Services LLC, P.O. Box 740256, Atlanta, GA 30374.

    Online dispute portal: https://www.equifax.com/personal/credit-report-services/credit-dispute/

    Send disputes by USPS certified mail with return receipt so you have proof of delivery for the 30-day FCRA investigation clock.

    Experian contact information

    Consumer phone: 1-888-397-3742 (1-888-EXPERIAN). Fraud and identity theft: 1-888-397-3742.

    Written dispute mailing address: Experian, P.O. Box 4500, Allen, TX 75013.

    Online dispute portal: https://www.experian.com/disputes/main.html

    Experian will accept a dispute referencing only the report number if you include it — but a full letter with account numbers and reasons produces stronger paper trails.

    TransUnion contact information

    Consumer phone: 1-800-916-8800. Fraud alerts: 1-800-680-7289.

    Written dispute mailing address: TransUnion Consumer Solutions, P.O. Box 2000, Chester, PA 19016.

    Online dispute portal: https://dispute.transunion.com

    TransUnion is often the fastest of the three bureaus to respond, but written certified-mail disputes still create the cleanest legal record.

    Which contact method should you use?

    For a legally strongest FCRA dispute, mail a written letter via USPS certified mail with return receipt to the addresses above. The bureau then has 30 days under 15 U.S.C. § 1681i to investigate.

    Online portals are faster but sometimes limit the evidence you can attach and the reasons you can select. Phone disputes are the weakest option — there is no paper trail.

    Frequently asked questions

    What to gather first

    • A current copy of each credit report you want to review (Equifax, Experian, TransUnion) from AnnualCreditReport.com.
    • Government-issued photo ID and proof of current address, which bureaus commonly request with a mailed dispute.
    • Account statements, payment records, or letters that relate to the item you believe is inaccurate or incomplete.
    • The exact account name, partial account number, and the reason you believe the entry is inaccurate or incomplete.
    • A way to keep records: copies of what you send and, if mailing, proof of delivery.

    Common mistakes to avoid

    • Disputing information you know is accurate — that wastes the process and does not help you.
    • Sending a vague dispute. Identify the specific item and explain what is inaccurate or incomplete.
    • Disputing with only one bureau when the same entry appears on more than one report.
    • Keeping no copies of what you sent, so you cannot show what was disputed or when.
    • Paying a company that promises deletions or score increases — no one can promise those outcomes.

    When to get additional help

    Consider additional help if a bureau or furnisher does not respond, if an entry you believe is inaccurate stays on your report after a reinvestigation, if you may be affected by identity theft, or if you have questions about your legal rights.

    How CreditKaren can help

    CreditKaren is a free, AI-assisted tool that reviews a credit report you upload and highlights entries that may be inconsistent, incomplete, or worth a closer look. If you decide an item may be inaccurate or incomplete, CreditKaren can draft a dispute letter you can review, edit, and send yourself.

    CreditKaren is not a law firm, credit bureau, lender, or credit-repair organization. It does not provide legal advice and does not guarantee deletions, dispute outcomes, or changes to your credit scores. You decide what to dispute and you send every letter.

    Important limitation

    Credit reporting disputes should be based on information you believe may be inaccurate, incomplete, unfamiliar, or improperly reported. Do not dispute information you know is accurate. A dispute does not guarantee a deletion, correction, score change, or other result.
