Massachusetts consumers may be at risk of identity theft in the latest national data breach. Cyber criminals were able to hack into personal information from a database of T-Mobile customers and applicants managed by Experian, a global credit and data company.

The breach included consumers’ names, addresses, Social Security numbers, dates of birth, and other identification numbers such as a driver’s license or passport number. However, no bank account information was compromised.

Consumers who applied for a T-Mobile account between Sept. 1, 2013 and before Sept. 16, 2015 may be at risk for identity theft.  Consumers should closely monitor their bank and credit accounts, along with their credit reports.

Experian is encouraging those who might be affected to go to www.ProtectMyID.com/SecurityIncident to register for two years of free credit monitoring. Customers can also call 866-369-0422 or send an e-mail to consumersupport@protectmyid.com if they have questions.
