T-Mobile US Inc. and a unit of credit-tracking firm Experian Plc are facing a growing list of lawsuits after hackers gained access to personal data on 15 million T-Mobile customers held on Experian servers.

The hack, revealed Oct. 1, exposed millions of Americans to potential identity theft, forcing customers and applicants to take costly actions to protect themselves from fraud, according to complaints filed as soon as a day later. By Wednesday, at least five such lawsuits were under way against T-Mobile and Experian, all seeking class-action status to represent everyone affected by the breach. A sixth lawsuit named only Experian.
