Credit report dispute

A dispute sent to the wrong address is not a dispute

There are two different letters here and they go to two different places. One goes to the credit bureau. One goes to the business that reported the item, and for that one the address is fixed by regulation: send it anywhere else and nobody has to investigate anything. This page sets out which letter is which, where each address actually comes from, and why the date it arrived is the part worth paying for.

Two letters, two addresses

1. A dispute to the credit bureau — Equifax, Experian or TransUnion. This is the one most people mean. Under the Fair Credit Reporting Act the bureau has to reinvestigate an item you dispute and tell you what it found, normally within 30 days of receiving your dispute (15 U.S.C. § 1681i).
2. A direct dispute to the furnisher — the bank, card issuer, lender or collector that reported the item in the first place. This is the letter that usually fixes the underlying record, and it is the one with a hard address rule attached.

Sending both is normal. They are separate processes with separate clocks, and the bureau dispute does not put the furnisher on notice by itself.

The furnisher address is set by regulation, not by preference

Regulation V, 12 CFR § 1022.43, governs direct disputes. A furnisher only has to investigate a dispute that reaches the address it has designated for disputes — the address it gave you in writing for that purpose, or the one printed on your consumer report or your billing statement for the account.

Read that the other way round and it is the reason so many disputes go nowhere. A carefully written letter to the customer service address on the back of the card, or to the head office, is a letter the furnisher is not obliged to treat as a dispute at all. Nothing happens, no clock starts, and months later the item is still there.

So before you write, find the dispute address in one of exactly three places: the notice the furnisher sent you about disputes, your own credit report next to the tradeline, or your billing statement. If none of them names one, the dispute goes through the bureau instead.

The bureau addresses change, and nobody publishes a stable one

This is worth being blunt about, because every third-party article that prints a P.O. Box for the three bureaus is making a promise it cannot keep. The Consumer Financial Protection Bureau declines to print them: its own guidance on disputing an error sends you to each bureau's site for "the current address you can mail your dispute to". Equifax does not show a mailing address on its contact page either; the address is printed on the dispute form you download that day. Experian's help pages behave the same way.

Piloxa therefore does not print one. Take the address from the form or the page on the day you send, and keep a copy of the page you took it from. That copy is worth having later, when the argument is about whether you sent it to the right place.

• Equifax — contact and dispute forms
• Experian — help and disputes
• TransUnion — dispute your credit

What the letter has to contain

1. Who you are: full legal name, current address, date of birth and the last four of your Social Security number. Bureaus reject disputes they cannot match to a file.
2. The item, named exactly as it appears on the report: creditor name, account number as printed, and the report date.
3. What is wrong with it, in one or two plain sentences. Not paid late. Not mine. Paid in full on this date. Balance wrong.
4. What you want done: corrected or deleted, and an updated report sent to you.
5. Copies of the proof, never originals: the statement, the payoff letter, the police report for identity theft.

Keep it to one page and one item where you can. A letter disputing eleven things at once invites a single blanket answer.

Why this letter in particular goes certified

The CFPB's own advice on the furnisher letter is one sentence long: "Send disputes to furnishers in writing, using certified mail." The reason is the clock. Every deadline in this process runs from the day the dispute was received, and the bureau or the furnisher is the one holding that date. Certified Mail moves the record of that date to your side of the table, which is the whole point of it.

If the dispute is ignored and the account later matters — a mortgage, a denied application, a lawsuit — the mailing record is what turns "I sent it" into a date a third party recorded.

What you end up holding

• The exact letter that was approved, kept unchanged, with the fingerprint that shows it is the same file.
• The recipient address as it was printed, after the postal check.
• The mailing record: the service that was bought, when the letter was handed over to be printed and mailed, and the reference the printer gave it.
• The sentence you authorized, and the time you authorized it.

You are buying USPS Certified Mail, so the Postal Service keeps its own delivery record. Piloxa asks the printing partner for that history on its own, without anyone pressing anything, and adds each scan to your record as it is reported, naming where it came from. If you chose the return receipt, the signature of whoever accepted the letter is recorded the same way once USPS releases it. Where nothing has come back, the record says “no record yet” rather than guessing. The sample record shows every state, including the incomplete ones.

Certified Mail proves that something was delivered. It does not prove what was inside. Keeping the approved letter beside the mailing record is what closes that gap, and it is the whole reason this exists. See a filled-in record.

Common questions

Where do I mail a dispute to Equifax, Experian or TransUnion?

To the address on the dispute form or dispute page of that bureau on the day you send it. None of the three publishes a stable mailing address on its contact page, and the Consumer Financial Protection Bureau deliberately does not print one either — it tells you to get the current address from the bureau. Any page that hands you a P.O. Box is quoting something that may already have moved.

Where do I send a dispute to the bank or collector that reported the item?

To the address that business designated for disputes: the one it gave you in writing for disputes, or the one printed on your consumer report or your billing statement for that account. That is the rule in 12 CFR 1022.43, and a dispute sent anywhere else does not have to be investigated.

Is the customer service address on my statement the dispute address?

Not automatically. Many statements print a separate address for billing enquiries or disputes, and that is the one to use. If the statement names only one address, use it and keep the statement.

Do I have to mail it, or can I dispute online?

You can dispute online, and it is faster. Mail is what you choose when you need the date provable later, or when you want the paper trail for a lawyer, a regulator complaint or a lawsuit. The CFPB’s own advice for disputes to furnishers is to send them in writing by certified mail.

How long does the bureau have to answer?

Normally 30 days from receiving your dispute, under 15 U.S.C. § 1681i, with a short extension if you send more information during the investigation. The count starts from receipt, which is the date Certified Mail records for you.

What does it cost to send?

$13.18 all in for a one-page letter by USPS Certified Mail, or $16.17 all in with the electronic return receipt, which records who signed for it. Printing, envelope and postage are included, with no subscription and no minimum.
