A step-by-step guide to writing FCRA dispute letters the bureaus must investigate, with a template and mailing checklist.

Most dispute letters fail for one reason: they are vague. "This isn't mine" gets a form reply. A specific, documented letter starts a legal 30-day investigation clock under the Fair Credit Reporting Act (FCRA §611).

Step 1: Pick one item per letter

Dispute one tradeline per letter so every response is traceable. Start with the item doing the most damage: accounts that aren't yours, duplicate or re-aged collections, then wrong late payments.

Step 2: State the exact error

Name the creditor, the partial account number, and what is wrong: "The balance is reported as $2,340; my statement dated March 3 shows $0." Facts, not feelings.

Step 3: Attach proof

Include copies (never originals) of your ID, proof of address, and the evidence: statements, payoff letters, police or FTC identity-theft reports.

Step 4: Ask for a specific outcome

Request deletion or correction, and ask for an updated copy of your report when the investigation ends.

Template

> Name, address, date of birth, last 4 of SSN

> To: [Equifax / Experian / TransUnion dispute address]

> I am disputing the following inaccurate information under FCRA §611: [Creditor], account ending [####]. It is inaccurate because [fact]. Enclosed is [evidence]. Please delete or correct this item and send me the results in writing.

> Signature

Step 5: Mail it certified

Send by certified mail with return receipt. Log the date — the bureau has 30 days (45 if you add evidence mid-investigation).

Step 6: If it's "verified," escalate

Request the method of verification, and dispute directly with the furnisher, who has its own accuracy duty under FCRA §623.
