AT&T Data Breach Settlement Denial Notices: Claimants Must Mail a Response by Oct. 17

Published September 23, 2026

Some people who filed claims in the $177 million AT&T data breach settlement have received notices from administrator Kroll saying their claims were denied. A claimant who wants the denial reconsidered must mail a signed Denial Response Form postmarked by October 17, 2026, or the claim will be rejected for good.

What Is This About?

Kroll Settlement Administration, which runs the claims process for In re: AT&T Inc. Customer Data Security Breach Litigation, MDL No. 3:24-md-03114-E in the U.S. District Court for the Northern District of Texas, has begun telling some claimants that their claim forms were denied. This is not a request to reconfirm information that every claimant receives. It goes only to people whose claims the administrator has rejected, and it gives them one chance to contest that decision.

A copy of the notice reviewed by OpenClassActions.com opens on Kroll's att-prod-forms.ksacms.com forms site, the same system that hosted the original AT&T claim form, under the title "Denial Response Form." It states that the claim form was received but denied, and asks the claimant to complete, sign and mail the attached Denial Response Form. The notice does not state a general reason for denials; the reason for any individual denial should appear on that claimant's own form.

What Does the Denial Notice Require?

The instructions on the notice are strict, and a response that ignores them will not be considered: Because the deadline is a postmark date, mailing well ahead of October 17 and keeping proof of mailing, such as a certificate of mailing from the post office, protects a claimant if the envelope is later questioned.

How Is This Different From the Deficiency Notices?

Earlier in 2026, the settlement website described a separate Notice of Deficient Claim Form, which asked some claimants to fix missing or incomplete information by September 8, 2026, through an online portal for emailed notices or by mail for paper notices. The denial notice appears to be the next stage: it goes to claims that the administrator has decided to deny, and the only way to answer it is by mail. A claimant who already answered a deficiency notice and then received a denial notice still needs to respond to the denial by October 17.

Where Does the AT&T Settlement Stand?

The settlement creates a $177 million fund covering two 2024 AT&T data incidents: a $149 million pool for the exposure of customer personal information and a $28 million pool for the theft of call and text records. The claim deadline was December 18, 2025, and about 4.38 million claims were filed.

The court held the final approval hearing on January 15, 2026. No final approval order had been entered as of September 23, 2026, and no payment date has been announced. Reviewing claims and sorting out denials is part of the administrator's work before any distribution, so these notices do not mean payments are about to begin. Our AT&T data breach settlement page tracks the approval and payment status.

Questions

Is the AT&T denial notice a scam?

The notices reviewed by OpenClassActions.com open on the att-prod-forms.ksacms.com domain, which is the same Kroll Settlement Administration forms system that hosted the original AT&T claim form, and they point readers to the official telecomdatasettlement.com website. To be safe, reach the form only through a link in a message you were expecting, or check your claim through the official settlement website, and never pay anyone to fix a settlement claim.

Can I email the AT&T Denial Response Form or use the website contact form?

No. The notice says responses sent by email or through the website's Contact Us form will not be accepted or answered. The signed form must be mailed to the address printed on the notice and postmarked by October 17, 2026. Each claimant must send their own response; bulk submissions are not accepted.

What happens if I ignore the AT&T denial notice?

According to the notice, a claimant who does not mail the Denial Response Form postmarked by October 17, 2026 will have the claim rejected and will receive no compensation for it.

Will I still get an electronic payment if I fix my AT&T claim?

Not necessarily. The notice warns that a claim may no longer be eligible for an electronic payment even if it is cured, which suggests a corrected claim could be paid another way, such as by check.

Is this the same as the AT&T deficiency notice due September 8, 2026?

No. The settlement website described an earlier Notice of Deficient Claim Form with a September 8, 2026 response deadline. The denial notice is a separate letter stating that a claim was denied, with its own October 17, 2026 mailing deadline.
