T-Mobile's 2021 breach exposed 76 million customers' Social Security numbers, license info, and account data. Documented-loss claims pay up to $25,000; everyone affected gets a baseline cash payment.
The T-Mobile 2021 breach exposed personal data of roughly 76 million customers, including current and former subscribers from 2018 onward. T-Mobile agreed to a $350M settlement fund in 2022. The administrator is processing claims now; the deadline to file documented losses has been extended.
In August 2021, attackers breached T-Mobile and exposed personal data of about 76 million current, former, and prospective subscribers, including Sprint customers absorbed in the merger. Exposed fields included names, Social Security numbers, driver's-license numbers, and birth dates.
T-Mobile agreed to a $350 million class action settlement; final approval came in June 2023. The settlement paid a baseline of about $25 to all class members ($100 for California residents) plus reimbursement of documented out-of-pocket losses up to $25,000. The claim filing window closed Jan 23, 2023; new filings are no longer accepted, but the matter remains relevant for those who filed and are awaiting payment.
What was exposed, what was paid, and where the matter stands now:
The claim window closed in January 2023, but if you filed before the deadline, the eligibility check above helps you confirm where your claim stands.
The $350M settlement broke into several categories. The status as of today:
| Diagnosis or claim type | Projected payout range | What drives the tier |
|---|---|---|
| Baseline cash payment (most class members) | ~$25 | Window closed Jan 2023. Paid pro rata after high claim volume; the actual amount depended on fund allocation. |
| California resident additional payment | ~$100 | Window closed Jan 2023. California's stricter privacy law triggered a separate sub-fund. |
| Documented out-of-pocket loss reimbursement | Up to $25,000 | Window closed Jan 2023. Identity-theft costs, fraud-related fees, and credit-freeze costs with documentation. |
| Time-spent reimbursement | $25 per hour (up to 15 hours) | Window closed Jan 2023. Time spent dealing with identity theft. |
| Free credit monitoring + ID theft restoration | 2 years | Enrollment window closed. Active enrollees continue coverage for the program's duration. |

Notices were mailed and emailed based on the contact info T-Mobile had on file at the time. If you changed address or email after being a customer, you may have missed the notice.
Distribution has been ongoing since 2023. Status can be checked at the official site using the claim number from your filing confirmation. Some payments may still be processing.
