Equifax Fax Number — Fax Credit Disputes and Reports

Equifax is one of the three national credit bureaus, and it accepts faxed dispute letters, identity theft affidavits, fraud alert requests, and credit freeze or thaw paperwork. Because Equifax routes these documents through different teams, the fax number you need depends on what you're submitting, so contact Equifax for the dispute fax line that matches your case. A faxed dispute gives you a dated confirmation that the bureau received your letter, which helps if Equifax later misses the 30-day investigation window the Fair Credit Reporting Act allows.

What You Can Fax to Equifax

  • Credit report dispute letters
  • Identity theft affidavits
  • Fraud alert requests
  • Credit freeze/thaw requests
  • Supporting documentation for disputes
Tip: Put your full name, the last four digits of your Social Security number, your date of birth, and current address on every page so Equifax can match the fax to your file. Many people fax the dispute and also send a copy by certified mail, since that combination creates two independent records of when the bureau received your documents. Keep the fax confirmation receipt with your dispute letter and any supporting paperwork in case you need to escalate to the CFPB later.

Faxing to Equifax — FAQ

No. Equifax handles disputes, fraud alerts, and identity theft reports through separate teams, and the fax number can vary by the type of request and your location. Contact Equifax directly to confirm the correct line before you send, rather than reusing a number from an old letter.

Include your full name, date of birth, current address, and the last four digits of your Social Security number on each page. Equifax uses these details to locate your credit file, and a dispute that can't be matched to a file may be returned or delayed.

Doing both is common. Faxing gets the affidavit to Equifax quickly and produces a delivery confirmation, while a certified mail copy gives you a second dated record. If you've placed a fraud alert, keep proof of when that request reached the bureau too.

The Fair Credit Reporting Act gives Equifax 30 days to investigate most disputes, and that clock starts when the bureau receives your documents. A fax confirmation showing the date and time of delivery establishes when the window opened, which matters if you later complain to the CFPB about a missed deadline.

Send only the information the dispute requires and add a cover page marking the fax confidential and naming the Equifax team it's going to. Using a service that transmits over an encrypted connection reduces exposure compared with a shared office machine where pages can sit in a tray.
