Experian / T-Mobile Data Breach Settlement: Payouts and Status

Last updated: July 26, 2026

The Experian / T-Mobile data breach settlement is closed — the claim deadline was April 11, 2019 and payments were made after final approval in May 2019. Experian Information Solutions, Inc., one of the three national credit bureaus, agreed to a $22 million non-reversionary cash fund to settle claims arising from a 2015 breach of one of its servers. The stolen file held the credit-check records of approximately 15 million people who had applied for T-Mobile postpaid service or device financing between September 1, 2013 and September 16, 2015. Class members could claim reimbursement of documented fraud losses and breach-response costs up to $10,000, plus compensation for their time at $20 per hour, and everyone in the class was offered at least two years of credit monitoring and identity-theft insurance.

Experian detected the intrusion on September 15, 2015, confirmed on September 22, 2015 that a single file containing the T-Mobile data had been stolen, and the breach was announced publicly on October 1, 2015. The exposed records included names, addresses and dates of birth, along with encrypted Social Security numbers and identification numbers such as driver's license, passport or military ID numbers — encryption that Experian said may have been compromised.

The consolidated case was In re Experian Data Breach Litigation, No. 8:15-cv-01592-AG-DFM, before Judge Andrew J. Guilford in the U.S. District Court for the Central District of California. The parties reached the $22 million deal on November 12, 2018, claims closed on April 11, 2019, and the court granted final approval in May 2019. Important: this is not the 2021 T-Mobile breach. That was a separate $350 million settlement covering about 76 million people, with its own deadline of January 23, 2023.

Official settlement administrator: Texas Attorney General — Experian/T-Mobile breach settlements

Who qualifies

  • The class covered consumers whose personal information was on the Experian server that was breached — people who applied for T-Mobile postpaid wireless service or device financing, and therefore had a credit check run through Experian, between September 1, 2013 and September 16, 2015.
  • About 15 million people were affected. Notice went to those Experian and T-Mobile could identify from their records; the October 2015 breach notification letters are how most class members learned they were included.
  • Cash claims required documentation. Class members could seek reimbursement for out-of-pocket costs and fraud losses traceable to the breach, up to $10,000, and for time spent dealing with it at $20 per hour — capped at two hours without documentation and seven hours with it.
  • Credit monitoring and identity-theft insurance were available to class members regardless of whether they had suffered any identified loss.
  • This settlement did not cover T-Mobile's own 2021 breach, and it did not cover Experian customers generally — only people whose data was in the specific T-Mobile credit-application file that was stolen.

What happened, and what you can still do

  1. 1

    Claims closed in April 2019

    The deadline to file was April 11, 2019, following the November 12, 2018 settlement and ahead of final approval in May 2019. There is no late-claim process and no money left in the fund. KCC LLC administered the claims and its role has ended.

  2. 2

    Be careful with the old settlement web address

    The web address that once hosted this settlement's claim site, expdatabreachsettlement.com, is no longer an official settlement site — the domain now serves unrelated advertising redirects. Do not enter personal information, Social Security numbers or bank details there. Retired settlement domains are frequently re-registered by third parties once a case ends.

  3. 3

    The state settlements were separate — and paid the states

    In November 2022, 40 state attorneys general reached a combined $16 million in settlements over Experian's breaches: about $12.67 million from Experian and $2.43 million from T-Mobile over the 2015 incident, plus $1 million over a separate 2012 Experian Data Corp breach. That money went to the states, not to consumers. Texas separately collected over $1.5 million from Experian and T-Mobile. Consumers affected by the 2015 breach were offered five years of free credit monitoring and two free annual credit reports through the multistate deal, but that enrollment window — six months from the November 7, 2022 announcement — has closed.

  4. 4

    Protect the data that was exposed

    Social Security numbers do not expire, so exposure from a 2015 breach still matters in 2026. You can freeze your credit file for free at all three bureaus — Experian, Equifax and TransUnion — request your free reports at annualcreditreport.com, and report identity theft at identitytheft.gov. A freeze is the single most effective free step, and it does not affect your credit score.

Frequently asked questions

Can I still file an Experian data breach settlement claim?

No. The claim deadline in the Experian / T-Mobile data breach settlement was April 11, 2019 and the $22 million fund has been distributed. The case received final approval in May 2019 and the claims administrator, KCC LLC, has closed the program. No late claims are accepted.

How much did the Experian data breach settlement pay?

The fund was $22 million in cash. Individual payments depended on what a class member claimed: reimbursement of documented out-of-pocket costs and fraud losses up to $10,000, plus time spent dealing with the breach at $20 per hour — capped at two hours undocumented or seven hours with documentation. Class members were also offered at least two years of credit monitoring and identity-theft insurance.

Who was affected by the 2015 Experian breach?

About 15 million people who applied for T-Mobile postpaid service or device financing between September 1, 2013 and September 16, 2015. Their credit-check records sat on an Experian server, and a hacker stole a single file containing them. The data included names, addresses, dates of birth and encrypted Social Security and ID numbers, with Experian warning the encryption may have been compromised.

Is this the same as the T-Mobile data breach settlement?

No. This case was against Experian over a 2015 breach of its own server holding T-Mobile applicant data, and it settled for $22 million. The much larger T-Mobile settlement covered T-Mobile's own August 2021 breach of about 76 million people, paid $350 million, and had a claim deadline of January 23, 2023. They are separate cases with separate classes.

Is this related to the Equifax data breach settlement?

No — different credit bureau, different breach, different settlement. Equifax's 2017 breach affected about 147 million people and settled for at least $700 million. Experian's 2015 incident affected about 15 million T-Mobile applicants and settled for $22 million. Both are closed to new claims.

Did the state attorney general settlements pay consumers?

No. The combined $16 million reached with 40 state attorneys general in November 2022 was paid to the states themselves. Consumers affected by the 2015 breach were offered five years of free credit monitoring and two free annual credit reports as part of that deal, but the six-month enrollment window has closed.

What should I do now if my data was in the Experian breach?

Freeze your credit file with Experian, Equifax and TransUnion — it is free, reversible, and does not affect your credit score. Pull your reports at annualcreditreport.com to check for accounts you did not open, and if you find fraud, report it at identitytheft.gov to get a recovery plan. Social Security numbers exposed in 2015 remain usable to criminals today.

Was the Experian breach Experian's fault or T-Mobile's?

The class action was brought against Experian, because the breached server belonged to Experian, which processed T-Mobile's credit applications as a vendor. T-Mobile was not the settling defendant in the $22 million class action, though it did pay $2.43 million as part of the separate 2022 multistate attorney general settlements.
