AT&T Class Action Lawsuit: Deadline Approaches for $177 Million Data Breach Settlement

Current and former AT&T customers are urged to act soon, as the deadline to file a claim in the AT&T class action lawsuit approaches. The telecommunications giant has agreed to a $177 million settlement to resolve allegations stemming from two major data breaches disclosed in 2024. Eligible consumers can now submit claims through the official AT&T settlement claim form until December 18, 2025, to receive part of the AT&T data breach settlement.

The settlement follows one of the largest data security incidents in recent years, potentially affecting tens of millions of current and former AT&T customers across the U.S. 

Background: What Happened in the AT&T Data Breach 2024

On March 30, 2024, AT&T reported that customer data appeared on the dark web, revealing information belonging to approximately 73 million individuals, including about 7.6 million current customers and 65 million former account holders. According to AT&T’s disclosure, the dataset contained details that were last updated in 2019, as reported by Forbes.

Four months later, on July 12, 2024, the company disclosed a second breach after discovering that certain data had been illegally downloaded from an AT&T workspace hosted by third-party provider Snowflake, Inc. This second incident, known as the “AT&T 2 Data Incident,” exposed limited customer data such as telephone numbers, call counts, interaction durations, and, in some cases, cell site identification numbers.

Multiple lawsuits were filed nationwide following these disclosed breaches. In June 2024, the cases were consolidated before Judge Ada E. Brown in the U.S. District Court for the Northern District of Texas, under the title In Re: AT&T Inc. Customer Data Security Breach Litigation (MDL Docket No. 3:24-md-03114-E). 

What the AT&T Class Action Lawsuit Is About

The consolidated complaint alleges that AT&T failed to implement sufficient cybersecurity measures to protect customer data, leading to unauthorized exposure of sensitive personal information. The AT&T class action lawsuit claims that millions of consumers were left vulnerable to identity theft and fraud following the breaches.

According to court filings, the settlement creates two distinct groups: the AT&T 1 Settlement Class (for those affected by the March breach) and the AT&T 2 Settlement Class (for those impacted by the July breach).

Who Qualifies for the AT&T Data Breach Settlement

Eligibility depends on which data incident affected you:

• AT&T 1 settlement class: All U.S. residents whose personal data elements—including names, phone numbers, emails, billing account numbers, or Social Security numbers—were exposed in the March 2024 breach.
• AT&T 2 settlement class: AT&T account owners or users whose phone-related data was compromised in the July 2024 breach hosted on Snowflake’s cloud platform.
• Overlap settlement class members: Individuals affected by both breaches may qualify for compensation from each category separately, provided documentation for each claim is unique.

This AT&T privacy lawsuit generally extends to both current and former customers of AT&T and other providers that used its network.

How Much You Could Receive from the AT&T $177 Million Settlement

The AT&T data breach settlement provides several payment options depending on the type of loss and level of exposure.

For the AT&T 1 Settlement Class (March 2024 breach):

• Documented loss cash payment: Up to $5,000 for out-of-pocket losses incurred since 2019 that can be traced directly to the breach. Documentation must include receipts, bank statements, or other non-self-prepared records.
• Tier 1 or Tier 2 cash payments: Customers whose Social Security numbers were included in the breach are eligible for Tier 1 Cash Payments, worth five times more than Tier 2 Payments. The exact payment amounts depend on the number of valid claims filed and final court approval.

For the AT&T 2 Settlement Class (July 2024 breach):

• Documented loss cash payment: Up to $2,500 for verified financial losses related to the second breach.
• Tier 3 cash payment: An alternative option based on a pro rata share of the remaining settlement fund after administrative costs, legal fees, and service awards.

Those who qualify as overlap settlement class members may claim under both incidents. However, each documented loss claim typically must be supported by unique proof.

How to File a Claim for the AT&T Data Breach Settlement

Eligible claimants must complete and submit the AT&T settlement claim form to receive payment from the AT&T class action lawsuit. Claims can be submitted online through the official settlement website or by mail.

Claimants will need to provide personal information, identify which data incident affected them, and attach documentation of any financial loss or identity restoration expenses. Acceptable proof includes receipts, correspondence from financial institutions, or other official records.

Key Deadlines:

• Claim form submission: December 18, 2025
• Opt-out or objection deadline: November 17, 2025
• Final approval hearing: January 15, 2026, at 9:00 a.m. Central Time

If you do nothing, you will not receive any settlement benefits but will likely give up your right to pursue individual claims regarding the breaches. 

Why This Matters: Act Now If You Believe You’re Qualified

The AT&T data breach settlement represents a significant response to growing consumer concern over personal data protection. The incident revealed potential vulnerabilities not only in AT&T’s systems but also in third-party platforms handling sensitive information.

If you are a customer whose data was compromised in the breach, you may be eligible for the AT&T data breach compensation. Filing the claim form is the only way to receive benefits from the AT&T $177 million settlement.

Review your eligibility, gather necessary documentation, and file your claim as soon as possible to secure your portion of the AT&T cyberattack settlement.
