T-Mobile announced on Wednesday that the names, Social Security numbers, and information from driver’s licenses or other identification of just over 40 million former and prospective customers that applied for T-Mobile credit were exposed in a recent data breach.
In a press statement, T-Mobile said the same data for about 7.8 million current T-Mobile postpaid customers appears to be compromised.
The company added that no phone numbers, account numbers, PINs, passwords, or financial information from the nearly 50 million records and accounts were compromised.
The company also revealed that approximately 850,000 active T-Mobile prepaid customer names, phone numbers, and account PINs were exposed.
To avoid further data breath, T-Mobile said they proactively reset all of the PINs on those accounts.
The company also said that no Metro by T-Mobile, former Sprint prepaid, or Boost customers had their names or PINs exposed.
Moreover, T-Mobile said some additional information from inactive prepaid accounts was also accessed through prepaid billing files.
T-Mobile added that no customer financial information, credit card information, debit or other payment information, or Social Security numbers were in the inactive file.
The company based in Bellevue, Washington is now one of the country’s largest cellphone service carriers, along with AT&T and Verizon, after buying rival Sprint.
