P.F. Chang’s identified 33 restaurants where customer credit and debit card information might have been stolen.
The majority are located in California, with the rest scattered around the U.S.
The Chinese-themed restaurant chain first found out about the possible theft on June 10, when it was alerted to it by the Secret Service.
The company’s list of restaurants include the time frames when the potential theft of customer data might have occurred. Some incidents started as far back as October, 2013. The company advised customers who used their cards at those times to monitor their accounts for potential theft.
The company said it is continuing to investigate the situation in conjunction with outside firms and the Secret Service.
A spokeswoman for P.F. Chang’s was not immediately available to say whether the restaurant has seen a drop in sales since the incident was first announced.
The company said that it’s now safe for customers to use credit and debit cards at its restaurants. It also said that its Pei Wei Asian Diner chain of restaurants was not affected.
