It's been a long time since AT&T customers had their private information exposed by two major data breaches. Those folks are finally about to receive some compensation, but only if they actively file a claim by tomorrow's deadline.

There's now only one day left to file a claim for part of the massive settlement related to the 2024 AT&T data breaches. Millions of customers' personal information was exposed and, following a class action lawsuit, the company agreed to a $177 million settlement. 

If you were affected by the breach, you may be eligible for compensation of up to $7,500, but you'll need to file a claim online or by mail by tomorrow, Dec. 18, 2025. After midnight tomorrow, you're out of luck. Here's everything you need to know about how to file your claim and how the payouts are determined.

What were these data breaches at AT&T?

The two data breaches related to AT&T's current $177 million settlement occurred in 2019 and 2024, although the company didn't acknowledge the 2019 breach until March 2024, weeks after it detected customer data spreading on the dark web.

The 2019 breach involved personal data, including Social Security numbers, birth dates and legal names, and it affected 7.6 million current AT&T customers and 65.4 million former account holders. Soon after the disclosure, AT&T took the dramatic step of resetting passwords for all current customers who were included in the breach.

The second data breach covered by the legal settlement happened soon after the disclosure of the first. In April 2024, hackers accessed phone records from 2022 for nearly all of AT&T's US customers (approximately 109 million) stored in Snowflake, the company's cloud-based data warehouse. AT&T disclosed the breach in July 2024.

Associates of the hacker group ShinyHunters claimed responsibility for similar Snowflake attacks on about 165 companies in mid-2024. Two people were eventually arrested for the AT&T hack.

Multiple lawsuits for both data breaches were filed after both of AT&T's disclosures and were consolidated soon after. All parties in both of the breach lawsuits agreed to a settlement in March 2025.

The class affected by "AT&T 1 Data Incident" (the 2019 breach) will receive a $149 million payout in the proposed settlement, while the class included in "AT&T 2 Data Incident" (the 2024 Snowflake breach) will receive $28 million.

How do I file a claim in the AT&T settlement?

Kroll Settlement Administration, the organization managing AT&T's legal settlement, has created a website at telecomdatasettlement.com where eligible class members can file claims for compensation.

To file a claim for part of the settlement, you'll need to have a "Class Member ID," which should have been included in a notification from Kroll, most likely sent by email. If you cannot find the email, check your spam folder or other email filters.

If you believe you should be included in either part of the AT&T settlement and did not receive a notification, or if you're not sure if you're included, you can call the settlement administrator at 833-890-4930, or write to it at AT&T Data Incident Settlement; c/o Kroll Settlement Administration LLC; P.O. Box 5324; New York, NY 10150-5324.

Once you have a Claim Member ID from Kroll, you can complete the filing forms, including any documented information about losses you experienced because of either breach or both.

Traffic to the website for the AT&T settlement has been metered. I recently checked the claim submission form and received a Cloudflare warning: "We are experiencing a high volume of traffic and using a virtual queue to limit the number of users on the website at the same time." I had to wait 2 minutes to get in.

If you don't want to submit a claim online, you can also print and mail the settlement forms (all PDFs): claim for the 2019 breach; claim for the 2024 Snowflake breach; claim for people affected by both breaches. Mailed forms should be sent to the Kroll address above and postmarked by the same Dec. 18, 2025, deadline.

How much will payments be in the AT&T privacy settlement?

How much could victims receive if they were included in one or both of the specific AT&T data breaches? Many payouts will be ultimately based on the number of people who file claims, but we have some estimates from the terms of the settlement.

Individuals affected by the 2019 data breach who can demonstrate a "documented loss" may be eligible to receive up to $5,000. If someone cannot prove that loss, they'll receive one of two tiered cash payments, based on whether their Social Security number was included in the breach.

For the Snowflake breach of 2024, AT&T customers who were affected and can prove the same demonstrated loss with documentation can receive up to $2,500. Those who were affected but have no proof of loss will receive a "pro rata" share of the remaining money, meaning it will be divided evenly among them.

Those affected by the 2019 and 2024 data breaches can file claims for both classes. While it's not entirely clear whether someone with two demonstrated losses could receive the full amount of $7,500, there's nothing in the language of the settlement site that says they couldn't.
