    Angry about a wrong entry? Good. Turn that energy into a specific letter with proof attached.

    Medical Collection Dispute Letter

    Use if a medical bill was paid, covered by insurance, isn't yours, or the balance is wrong. The three bureaus have said they don't report paid medical collections or those under $500; rules for larger unpaid medical debt have been in flux, so check the CFPB's current guidance.

    To whom it may concern:
    
    I am disputing a medical collection reported by [collection agency] for $[amount]. This entry is inaccurate because [choose: it was paid on (date) / it was covered by insurance, see enclosed EOB / it is not my debt / the balance is wrong]. Paid medical collections and medical collections under $500 should not appear on my report under the bureaus' own stated policies.
    
    Under 15 U.S.C. § 1681i, please conduct a reasonable reinvestigation and correct or delete this information, then send me the results in writing. Enclosed are a copy of my ID, proof of address, and supporting documents.

    Late Payment Dispute Letter

    Use if a late payment is wrong — you paid on time, the account was in forbearance, or the creditor made an error. If the late payment is accurate, try a goodwill letter instead.

    To whom it may concern:
    
    My report shows a [30/60/90]-day late payment for [month/year] on this account. This is inaccurate: I paid on [date] as shown by the enclosed [bank statement / payment confirmation]. [Or: the account was in a forbearance / autopay error acknowledged by the creditor on (date).]
    
    Under 15 U.S.C. § 1681i, please conduct a reasonable reinvestigation and correct or delete this information, then send me the results in writing. Enclosed are a copy of my ID, proof of address, and supporting documents.

    Collection Account Dispute Letter

    Use if you don't recognize the debt, the details are wrong, or it's past the seven-year reporting period. You can also ask the collector to validate the debt within 30 days of their first notice.

    To whom it may concern:
    
    I am disputing a collection account reported by [collection agency] for $[amount]. [Choose: I do not recognize this debt / the original creditor or balance is wrong / the date of first delinquency is wrong / this debt is older than seven years and should no longer be reported / I requested validation on (date) and received none.]
    
    Under 15 U.S.C. § 1681i, please conduct a reasonable reinvestigation and correct or delete this information, then send me the results in writing. Enclosed are a copy of my ID, proof of address, and supporting documents.

    Identity Theft Block Letter

    Use when an account was opened in your name without permission. File an FTC Identity Theft Report first at IdentityTheft.gov — see our identity theft affidavit guide.

    To whom it may concern:
    
    I am a victim of identity theft. The account listed above was opened without my knowledge or permission. Enclosed is my FTC Identity Theft Report (report number [number]), proof of identity, and proof of address. Under 15 U.S.C. § 1681c-2, please block this information from my file within four business days and notify the furnisher.
    
    Under 15 U.S.C. § 1681i, please conduct a reasonable reinvestigation and correct or delete this information, then send me the results in writing. Enclosed are a copy of my ID, proof of address, and supporting documents.

    Duplicate Account Dispute Letter

    Use when one debt shows up twice — common after a debt is sold to a collector and the original creditor still shows a balance.

    Re: Dispute of inaccurate information — [Creditor name], account ending [last 4 digits]
    
    To whom it may concern:
    
    The same debt appears more than once on my report: [Account A — creditor, account ending, balance] and [Account B — creditor, account ending, balance]. Reporting one debt twice overstates what I owe. Please delete the duplicate entry and ensure only one accurate tradeline remains (the original creditor should show a $0 balance if the debt was sold).
    
    Under 15 U.S.C. § 1681i, please conduct a reasonable reinvestigation and correct or delete this information, then send me the results in writing. Enclosed are a copy of my ID, proof of address, and supporting documents.
    
    Sincerely,

    If the Bureau Says 'Verified'

    Dispute directly with the company that reported it, file a CFPB complaint, and keep records. Our verified-but-still-wrong guide walks through every escalation step.

    Frequently asked questions

    They work when the information really is inaccurate and you add specific facts and proof. Generic, copy-paste disputes of accurate items are often rejected as frivolous.

    Either is allowed. Certified mail with return receipt gives you a stronger paper trail if you later need to escalate.

    Generally 30 days from receiving your dispute, or 45 days if you send more information during the investigation or disputed after getting your free annual report.

    Yes, AI can draft or polish a letter, but you must verify every fact. CreditKaren drafts letters based on entries in your actual report for free.

    Yes. If it was paid, covered by insurance, not yours, or inaccurate, dispute it with each bureau showing it and attach your proof.

    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.
