ST. LOUIS, Mo. -- Two St. Louis P.F. Chang's location are among 33 restaurants where customer credit and debit card information may have been stolen.
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 Chesterfield location may have been breached between February 21 and June 11. The Richmond Heights location may have been breached between April 10 and June 11.
The company said, "the potentially stolen credit and debit card data includes the card number and in some cases also the cardholder's name and/or the card's expiration date. However, we have not determined that any specific cardholder's credit or debit card data was stolen by the intruder."
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.
In a statement, P.F. Chang's encouraged its guests to remain vigilant and seek to protect against possible identity theft or other financial loss by reviewing account statements for any unusual activity, notifying their credit card companies, and monitoring their credit reports.
