Where to Send Credit Dispute Letters: Bureaus and Creditors

Credit dispute letters go to a dedicated P.O. Box that each credit bureau maintains for consumer disputes. For the three major bureaus, the addresses are Equifax Information Services, LLC, P.O. Box 740256, Atlanta, GA 30374-0256; Experian, P.O. Box 4500, Allen, TX 75013; and TransUnion Consumer Solutions, P.O. Box 2000, Chester, PA 19016.¹ Use the full ZIP code, send a separate letter to each bureau reporting the error, and mail it in a way that gives you proof of delivery. The rest of this article covers what to put in the envelope, how to send it, and what happens once the bureau opens it.

The Three Major Credit Bureau Addresses

Equifax: Equifax Information Services, LLC, P.O. Box 740256, Atlanta, GA 30374-0256
Experian: P.O. Box 4500, Allen, TX 75013
TransUnion: TransUnion Consumer Solutions, P.O. Box 2000, Chester, PA 19016

Bureaus do not share disputes with one another. If the same error appears on two or three reports, mail a separate letter to each bureau involved.

Specialty Consumer Reporting Agencies

Not every “credit” problem lives at the big three. If you’ve been denied a checking account, flagged during an insurance quote, or turned down by a lender that uses a smaller bureau, your file is somewhere else. These are the dispute addresses for the agencies that come up most often:

ChexSystems (banking and checking account history): Chex Systems, Inc., Attn: Consumer Relations, P.O. Box 583399, Minneapolis, MN 55458²
LexisNexis Risk Solutions (insurance and public records): LexisNexis Risk Solutions Consumer Center, P.O. Box 105108, Atlanta, GA 30348-5108³
Innovis (fourth national credit bureau): Innovis Consumer Assistance, P.O. Box 530088, Atlanta, GA 30353-0088⁴

Your dispute rights under federal law apply to these agencies the same way they apply to Equifax, Experian, and TransUnion.

Sending a Dispute Directly to the Creditor

You can also mail the dispute to the company that reported the information in the first place. Federal law calls those companies “furnishers” (banks, card issuers, collection agencies) and gives them their own duty to investigate consumer disputes.⁵

The address usually sits right on your credit report, next to the tradeline for that account. A recent billing statement or letter from the company works too. Filing with the bureau and the furnisher at the same time opens two parallel investigations, which sometimes moves things along faster than either one alone.

What to Put in the Letter

A dispute doesn’t need to be long. It does need enough information for the bureau to identify you, find the account, and understand exactly what you’re challenging. Federal regulations spell out the minimum for a direct dispute to a furnisher: enough to identify the account, a clear explanation of the error, and any supporting documentation.⁶ Disputes to the bureaus work the same way, and thin letters get bounced as frivolous.

Include:

Your full legal name, current address, date of birth, and Social Security number.
The account number and the creditor’s name exactly as they appear on your report.
A specific statement of what’s wrong. “This account is not mine” or “this payment was reported 30 days late but was paid on time on [date]” works. “Please verify everything” invites a frivolous determination.
Copies of supporting documents, never originals. Bank statements, payment confirmations, cancelled checks, letters from the creditor.
A copy of a government-issued ID and a recent utility bill or bank statement showing your current address, so the bureau can confirm who you are without an extra round of correspondence.

Keep it to a single page when you can. A focused letter reads faster and gets a better result than a five-page narrative.

Identity Theft Disputes

If the disputed account is fraudulent, the process shifts. Under federal law, a bureau must block information you identify as resulting from identity theft within four business days of receiving your request, as long as you provide four things: proof of identity, a copy of an identity theft report, identification of the specific fraudulent information, and a statement that the accounts are not yours.⁷

The identity theft report is the piece most people don’t have. You can generate one for free at IdentityTheft.gov, run by the Federal Trade Commission. A police report, if your local department will take one, helps too. Without the identity theft report, the bureau still has to investigate, but on the standard 30-day timeline rather than the four-day block.

How to Mail It

Send every dispute by USPS Certified Mail with Return Receipt Requested. The investigation clock starts when the bureau receives your letter, so proof of the receipt date protects you if a bureau later says the letter never arrived. The signed return receipt settles that question.

At the counter you’ll get a tracking number and a mailing receipt, and you can pick either a physical green return receipt card or an electronic version you check online. As of January 2026, certified mail costs $5.30, and the return receipt adds $2.82 electronic or $4.40 for the card, on top of regular first-class postage.⁸ Figure roughly $9 to $11 per letter, so a full round of disputes to all three bureaus runs $27 to $33 in postage.

Before you seal the envelope, photocopy everything: the letter, every attachment, and the front of the addressed envelope. File those copies with your certified mail receipt. If anything goes sideways later, that folder is your evidence.

What Happens After the Bureau Gets Your Letter

The bureau generally has 30 days from receipt to complete the investigation.⁹ During that window it contacts the furnisher, forwards your documents, and asks the furnisher to verify or correct the data.

Two situations stretch the deadline to 45 days: filing a dispute after receiving your free annual credit report, and submitting additional supporting information during the initial 30-day window.⁹ If you pulled your file through AnnualCreditReport.com and then disputed, the longer window applies automatically.

Once the investigation ends, the bureau has five business days to send you the results in writing along with an updated report if anything changed.¹⁰ Unverified or inaccurate information has to be deleted or corrected. If the furnisher confirms the item, it stays.

If Your Dispute Comes Back Rejected

Bureaus and furnishers can decline to investigate when they consider a dispute frivolous or irrelevant, usually because you didn’t give them enough to work with or you resubmitted the same complaint without new evidence.¹⁰ When that happens, the bureau has to notify you within five business days and explain why. Form letters produced by credit repair mills get flagged this way often, because furnishers recognize the templates.

The fix is to resubmit with more specificity: a copy of your ID, a detailed explanation of what’s actually wrong, and any documentation that supports your version.

If the investigation finishes and the bureau keeps the item on your file, you can add a brief consumer statement (up to 100 words) explaining your side, and that statement becomes part of your report.¹⁰ Automated underwriting systems rarely read these, but manual reviewers on mortgages and background checks sometimes do. You can also file a complaint at consumerfinance.gov; the CFPB forwards it to the bureau or furnisher and tracks the response.¹¹

When You Can Skip the Mail

Mail isn’t the only channel. All three major bureaus accept disputes online, and Equifax and TransUnion also take them by phone:

Equifax: equifax.com/personal/credit-report-services/credit-dispute/ or (866) 349-5191
Experian: the Dispute Center after signing in at experian.com
TransUnion: transunion.com or (800) 916-8800

Online disputes let you upload documents and often finish faster, but you lose the certified-mail paper trail. For a wrong address or a balance that’s already been corrected, the online form is fine. For anything involving large sums, identity theft, or a fight you may need to escalate later, spend the postage.
